 NetCDF files are self-describing, network-transparent, directly accessible, and extendible.  `Self-describing` means that a netCDF file includes information about the data it contains.  `Network-transparent` means that a netCDF file is represented in a form that can be accessed by computers with different ways of storing integers, characters, and floating-point numbers.  `Direct-access` means that a small subset of a large dataset may be accessed efficiently, without first reading throug [...]

 ### 4.4-beta1	Released 2012-03-02
 
 * `Fortran 2003 Support`
-       
+
     Version 4.4 is the first release to support fortran 2003 and to use the ISO C Bindings available in fortran 2003 to replace the older C code wrappers.
 
     Congratulations and thanks to Richard Weed at Mississippi State University, who is the author of new code.
-

     See the file `README_F03_MODS` for a more complete description of the changes. Many changes to the build structure have been made at the same time as the new 2003 code has been inserted.
 
-    As part of the fortran 2003 refactor, the directory structure has been significantly modified.  All the previous F90 C wrapper code has been moved to the "libsrc" directory. 
+    As part of the fortran 2003 refactor, the directory structure has been significantly modified.  All the previous F90 C wrapper code has been moved to the "libsrc" directory.
 
     All of the fortran code has been moved to the "fortran" directory. The directories names F77 and F90 have been removed. The most important consequence of this refactor is that pure Fortran77 compilers are no longer supported. It is assumed that the compiler supports at least Fortran 90 and also Fortran 77.  If it also supports the ISO C Bindings, then the new 2003 code is used instead of the older C wrappers.

+1. Use of the NetCDF Library {.chapter}
+============================
+
+You can use the netCDF library without knowing about all of the netCDF
+interface. If you are creating a netCDF dataset, only a handful of
+routines are required to define the necessary dimensions, variables, and
+attributes, and to write the data to the netCDF dataset. (Even less are
+needed if you use the ncgen utility to create the dataset before running
+a program using netCDF library calls to write data. See
+[(netcdf)ncgen](netcdf.html#ncgen) section ‘ncgen’ in NetCDF Users
+Guide.) Similarly, if you are writing software to access data stored in
+a particular netCDF object, only a small subset of the netCDF library is
+required to open the netCDF dataset and access the data. Authors of
+generic applications that access arbitrary netCDF datasets need to be
+familiar with more of the netCDF library.
+
+In this chapter we provide templates of common sequences of netCDF calls
+needed for common uses. For clarity we present only the names of
+routines; omit declarations and error checking; omit the type-specific
+suffixes of routine names for variables and attributes; indent
+statements that are typically invoked multiple times; and use ... to
+represent arbitrary sequences of other statements. Full parameter lists
+are described in later chapters.

+|                                      | save new netCDF dataset              |
+|                                      | ```                                  |
++--------------------------------------+--------------------------------------+
+
+Only one call is needed to create a netCDF dataset, at which point you
+will be in the first of two netCDF modes. When accessing an open netCDF
+dataset, it is either in define mode or data mode. In define mode, you
+can create dimensions, variables, and new attributes, but you cannot
+read or write variable data. In data mode, you can access data and
+change existing attributes, but you are not permitted to create new
+dimensions, variables, or attributes.
+
+One call to NF90\_DEF\_DIM is needed for each dimension created.
+Similarly, one call to NF90\_DEF\_VAR is needed for each variable
+creation, and one call to a member of the NF90\_PUT\_ATT family is
+needed for each attribute defined and assigned a value. To leave define
+mode and enter data mode, call NF90\_ENDDEF.
+
+Once in data mode, you can add new data to variables, change old values,
+and change values of existing attributes (so long as the attribute
+changes do not require more storage space). Data of all types is written
+to a netCDF variable using the NF90\_PUT\_VAR subroutine. Single values,
+arrays, or array sections may be supplied to NF90\_PUT\_VAR; optional
+arguments allow the writing of subsampled or mapped portions of the
+variable. (Subsampled and mapped access are general forms of data access
+that are explained later.)
+
+Finally, you should explicitly close all netCDF datasets that have been
+opened for writing by calling NF90\_CLOSE. By default, access to the
+file system is buffered by the netCDF library. If a program terminates
+abnormally with netCDF datasets open for writing, your most recent
+modifications may be lost. This default buffering of data is disabled by
+setting the NF90\_SHARE flag when opening the dataset. But even if this
+flag is set, changes to attribute values or changes made in define mode
+are not written out until NF90\_SYNC or NF90\_CLOSE is called.

+1.2 Reading a NetCDF Dataset with Known Names {.section}
+---------------------------------------------
+
+Here we consider the case where you know the names of not only the
+netCDF datasets, but also the names of their dimensions, variables, and
+attributes. (Otherwise you would have to do "inquire" calls.) The order
+of typical C calls to read data from those variables in a netCDF dataset
+is:

+
+First, a single call opens the netCDF dataset, given the dataset name,
+and returns a netCDF ID that is used to refer to the open netCDF dataset
+in all subsequent calls.
+
+Next, a call to NF90\_INQ\_DIMID for each dimension of interest gets the
+dimension ID from the dimension name. Similarly, each required variable
+ID is determined from its name by a call to NF90\_INQ\_VARID. Once
+variable IDs are known, variable attribute values can be retrieved using
+the netCDF ID, the variable ID, and the desired attribute name as input
+to NF90\_GET\_ATT for each desired attribute. Variable data values can
+be directly accessed from the netCDF dataset with calls to
+NF90\_GET\_VAR.
+
+Finally, the netCDF dataset is closed with NF90\_CLOSE. There is no need
+to close a dataset open only for reading.

+1.3 Reading a netCDF Dataset with Unknown Names {.section}
+-----------------------------------------------
+
+It is possible to write programs (e.g., generic software) which do such
+things as processing every variable, without needing to know in advance
+the names of these variables. Similarly, the names of dimensions and
+attributes may be unknown.
+
+Names and other information about netCDF objects may be obtained from
+netCDF datasets by calling inquire functions. These return information
+about a whole netCDF dataset, a dimension, a variable, or an attribute.
+The following template illustrates how they are used:
+

+|                                      |  attribute names                     |

+|                                      |            NF90_GET_ATT        ! get |
+|                                      |  attribute values                    |

+|                                      |         NF90_GET_VAR           ! get |
+|                                      |  values of variables                 |

+|                                      |      NF90_CLOSE                ! clo |
+|                                      | se netCDF dataset                    |
+|                                      | ```                                  |
++--------------------------------------+--------------------------------------+
+
+As in the previous example, a single call opens the existing netCDF
+dataset, returning a netCDF ID. This netCDF ID is given to the
+NF90\_INQUIRE routine, which returns the number of dimensions, the
+number of variables, the number of global attributes, and the ID of the
+unlimited dimension, if there is one.
+
+All the inquire functions are inexpensive to use and require no I/O,
+since the information they provide is stored in memory when a netCDF
+dataset is first opened.
+
+Dimension IDs use consecutive integers, beginning at 1. Also dimensions,
+once created, cannot be deleted. Therefore, knowing the number of
+dimension IDs in a netCDF dataset means knowing all the dimension IDs:
+they are the integers 1, 2, 3, ...up to the number of dimensions. For
+each dimension ID, a call to the inquire function
+NF90\_INQUIRE\_DIMENSION returns the dimension name and length.
+
+Variable IDs are also assigned from consecutive integers 1, 2, 3, ... up
+to the number of variables. These can be used in NF90\_INQUIRE\_VARIABLE
+calls to find out the names, types, shapes, and the number of attributes
+assigned to each variable.
+
+Once the number of attributes for a variable is known, successive calls
+to NF90\_INQ\_ATTNAME return the name for each attribute given the
+netCDF ID, variable ID, and attribute number. Armed with the attribute
+name, a call to NF90\_INQUIRE\_ATTRIBUTE returns its type and length.
+Given the type and length, you can allocate enough space to hold the
+attribute values. Then a call to NF90\_GET\_ATT returns the attribute
+values.
+
+Once the IDs and shapes of netCDF variables are known, data values can
+be accessed by calling NF90\_GET\_VAR.

+
+1.4 Writing Data in an Existing NetCDF Dataset {.section}
+----------------------------------------------
+
+With write access to an existing netCDF dataset, you can overwrite data
+values in existing variables or append more data to record variables
+along the unlimited (record) dimension. To append more data to
+non-record variables requires changing the shape of such variables,
+which means creating a new netCDF dataset, defining new variables with
+the desired shape, and copying data. The netCDF data model was not
+designed to make such "schema changes" efficient or easy, so it is best
+to specify the shapes of variables correctly when you create a netCDF
+dataset, and to anticipate which variables will later grow by using the
+unlimited dimension in their definition.
+
+The following code template lists a typical sequence of calls to
+overwrite some existing values and add some new records to record
+variables in an existing netCDF dataset with known variable names:
+
++--------------------------------------+--------------------------------------+
+|                                      | ``` {.example}                       |
+|                                      |      NF90_OPEN             ! open ex |
+|                                      | isting netCDF dataset                |
+|                                      |        ...                           |
+|                                      |        NF90_INQ_VARID      ! get var |
+|                                      | iable IDs                            |
+|                                      |        ...                           |
+|                                      |        NF90_PUT_VAR        ! provide |
+|                                      |  new values for variables, if any    |
+|                                      |        ...                           |
+|                                      |        NF90_PUT_ATT        ! provide |
+|                                      |  new values for attributes, if any   |
+|                                      |          ...                         |
+|                                      |      NF90_CLOSE            ! close n |
+|                                      | etCDF dataset                        |
+|                                      | ```                                  |
++--------------------------------------+--------------------------------------+
+
+A netCDF dataset is first opened by the NF90\_OPEN call. This call puts
+the open dataset in data mode, which means existing data values can be
+accessed and changed, existing attributes can be changed, but no new
+dimensions, variables, or attributes can be added.
+
+Next, calls to NF90\_INQ\_VARID get the variable ID from the name, for
+each variable you want to write. Then each call to NF90\_PUT\_VAR writes
+data into a specified variable, either a single value at a time, or a
+whole set of values at a time, depending on which variant of the
+interface is used. The calls used to overwrite values of non-record
+variables are the same as are used to overwrite values of record
+variables or append new data to record variables. The difference is
+that, with record variables, the record dimension is extended by writing
+values that don’t yet exist in the dataset. This extends all record
+variables at once, writing "fill values" for record variables for which
+the data has not yet been written (but see section [Fill
+Values](#Fill-Values) to specify different behavior).
+
+Calls to NF90\_PUT\_ATT may be used to change the values of existing
+attributes, although data that changes after a file is created is
+typically stored in variables rather than attributes.
+
+Finally, you should explicitly close any netCDF datasets into which data
+has been written by calling NF90\_CLOSE before program termination.
+Otherwise, modifications to the dataset may be lost.

+1.5 Adding New Dimensions, Variables, Attributes {.section}
+------------------------------------------------
+
+An existing netCDF dataset can be extensively altered. New dimensions,
+variables, and attributes can be added or existing ones renamed, and
+existing attributes can be deleted. Existing dimensions, variables, and
+attributes can be renamed. The following code template lists a typical
+sequence of calls to add new netCDF components to an existing dataset:

++--------------------------------------+--------------------------------------+
+
+A netCDF dataset is first opened by the NF90\_OPEN call. This call puts
+the open dataset in data mode, which means existing data values can be
+accessed and changed, existing attributes can be changed (so long as
+they do not grow), but nothing can be added. To add new netCDF
+dimensions, variables, or attributes you must enter define mode, by
+calling NF90\_REDEF. In define mode, call NF90\_DEF\_DIM to define new
+dimensions, NF90\_DEF\_VAR to define new variables, and NF90\_PUT\_ATT
+to assign new attributes to variables or enlarge old attributes.
+
+You can leave define mode and reenter data mode, checking all the new
+definitions for consistency and committing the changes to disk, by
+calling NF90\_ENDDEF. If you do not wish to reenter data mode, just call
+NF90\_CLOSE, which will have the effect of first calling NF90\_ENDDEF.
+
+Until the NF90\_ENDDEF call, you may back out of all the redefinitions
+made in define mode and restore the previous state of the netCDF dataset
+by calling NF90\_ABORT. You may also use the NF90\_ABORT call to restore
+the netCDF dataset to a consistent state if the call to NF90\_ENDDEF
+fails. If you have called NF90\_CLOSE from definition mode and the
+implied call to NF90\_ENDDEF fails, NF90\_ABORT will automatically be
+called to close the netCDF dataset and leave it in its previous
+consistent state (before you entered define mode).
+
+At most one process should have a netCDF dataset open for writing at one
+time. The library is designed to provide limited support for multiple
+concurrent readers with one writer, via disciplined use of the
+NF90\_SYNC function and the NF90\_SHARE flag. If a writer makes changes
+in define mode, such as the addition of new variables, dimensions, or
+attributes, some means external to the library is necessary to prevent
+readers from making concurrent accesses and to inform readers to call
+NF90\_SYNC before the next access.

+1.6 Error Handling {.section}
+------------------
+
+The netCDF library provides the facilities needed to handle errors in a
+flexible way. Each netCDF function returns an integer status value. If
+the returned status value indicates an error, you may handle it in any
+way desired, from printing an associated error message and exiting to
+ignoring the error indication and proceeding (not recommended!). For
+simplicity, the examples in this guide check the error status and call a
+separate function to handle any errors.
+
+The NF90\_STRERROR function is available to convert a returned integer
+error status into an error message string.
+
+Occasionally, low-level I/O errors may occur in a layer below the netCDF
+library. For example, if a write operation causes you to exceed disk
+quotas or to attempt to write to a device that is no longer available,
+you may get an error from a layer below the netCDF library, but the
+resulting write error will still be reflected in the returned status
+value.

+1.7 Compiling and Linking with the NetCDF Library {.section}
+-------------------------------------------------
+
+Details of how to compile and link a program that uses the netCDF C or
+Fortran interfaces differ, depending on the operating system, the
+available compilers, and where the netCDF library and include files are
+installed. Nevertheless, we provide here examples of how to compile and
+link a program that uses the netCDF library on a Unix platform, so that
+you can adjust these examples to fit your installation.
+
+Every Fortran 90 procedure or module which references netCDF constants
+or procedures must have access to the module information created when
+the netCDF module was compiled. The suffix for this file is “MOD” (or
+sometimes “mod”).
+
+Most F90 compilers allow the user to specify the location of .MOD files,
+usually with the -I flag.
+
++--------------------------------------+--------------------------------------+
+|                                      | ``` {.example}                       |
+|                                      | f90 -c -I/usr/local/include mymodule |
+|                                      | .f90                                 |
+|                                      | ```                                  |
++--------------------------------------+--------------------------------------+
+
+Starting with version 3.6.2, another method of building the netCDF
+fortran libraries became available. With the –enable-separate-fortran
+option to configure, the user can specify that the C library should not
+contain the fortran functions. In these cases an additional library,
+libnetcdff.a (note the extra “f”) will be built. This library contains
+the Fortran functions. Since verion 4.1.3, the netCDF Fortran software
+and library is always distinct from the netCDF C library, but depends on
+it. If it is installed as a shared library, you need only use
+‘-lnetcdff’ to specify the Fortran library for linking.
+
+For more information about configure options, See
+[(netcdf-install)Specifying the Environment for
+Building](netcdf-install.html#Specifying-the-Environment-for-Building)
+section ‘Specifying the Environment for Building’ in The NetCDF
+Installation and Porting Guide.
+
+If installed as a shared library, link, using something like:
+
++--------------------------------------+--------------------------------------+
+|                                      | ``` {.example}                       |
+|                                      | f90 -o myprogram myprogram.o -L/usr/ |
+|                                      | local/lib -lnetcdff                  |
+|                                      | ```                                  |
++--------------------------------------+--------------------------------------+
+
+If installed as a static library, you will at least need to mention the
+netCDF C library and perhaps other libraries, such as hdf5 or curl,
+depending on how the C library was built. For example:
+
++--------------------------------------+--------------------------------------+
+|                                      | ``` {.example}                       |
+|                                      | f90 -o myprogram myprogram.o -L/usr/ |
+|                                      | local/lib -lnetcdff -lnetcdf         |
+|                                      | ```                                  |
++--------------------------------------+--------------------------------------+
+
+Use of the nf-config utility program, installed as part of the
+netcdf-fortran software, provides an easier way to compile and link,
+without needing to know the details of where the library has been
+installed, or whether it is installed as a shared or static library.
+
+To see all the options for ‘nf-config’, invoke it with the ‘–help’
+argument.
+
+Here’s an example of how you could use ‘nf-config’ to compile and link a
+Fortran program in one step:
+
++--------------------------------------+--------------------------------------+
+|                                      | ``` {.example}                       |
+|                                      | f90 myprogram.f90 -o myprogram `nf-c |
+|                                      | onfig --fflags --flibs`              |
+|                                      | ```                                  |
++--------------------------------------+--------------------------------------+
+
+If it is installed on your system, you could also use the ‘pkg-config’
+utility to compile and link Fortran programs with the netCDF libraries.
+This is especially useful in Makefiles, to insulate them from changes to
+library versions and dependencies. Here is an example of how you could
+compile and link a Fortran program with netCDF libraries using
+pkg-config:
+
++--------------------------------------+--------------------------------------+
+|                                      | ``` {.example}                       |
+|                                      | export PKG_CONFIG_PATH=/usr/local/li |
+|                                      | b/pkgconfig                          |
+|                                      | f90 myprogram.f90 -o myprogram `pkg- |
+|                                      | config --cflags --libs netcdf-fortra |
+|                                      | n`                                   |
+|                                      | ```                                  |
++--------------------------------------+--------------------------------------+
+
+where here ‘–cflags’ means compiler flags and ‘libs’ requests that the
+approriate libraries be linked in.

+2.1 Datasets Introduction {.section}
+-------------------------
+
+This chapter presents the interfaces of the netCDF functions that deal
+with a netCDF dataset or the whole netCDF library.
+
+A netCDF dataset that has not yet been opened can only be referred to by
+its dataset name. Once a netCDF dataset is opened, it is referred to by
+a netCDF ID, which is a small nonnegative integer returned when you
+create or open the dataset. A netCDF ID is much like a file descriptor
+in C or a logical unit number in FORTRAN. In any single program, the
+netCDF IDs of distinct open netCDF datasets are distinct. A single
+netCDF dataset may be opened multiple times and will then have multiple
+distinct netCDF IDs; however at most one of the open instances of a
+single netCDF dataset should permit writing. When an open netCDF dataset
+is closed, the ID is no longer associated with a netCDF dataset.
+
+Functions that deal with the netCDF library include:
+
+-   Get version of library.
+-   Get error message corresponding to a returned error code.
+
+The operations supported on a netCDF dataset as a single object are:
+
+-   Create, given dataset name and whether to overwrite or not.
+-   Open for access, given dataset name and read or write intent.
+-   Put into define mode, to add dimensions, variables, or attributes.
+-   Take out of define mode, checking consistency of additions.
+-   Close, writing to disk if required.
+-   Inquire about the number of dimensions, number of variables, number
+    of global attributes, and ID of the unlimited dimension, if any.
+-   Synchronize to disk to make sure it is current.
+-   Set and unset nofill mode for optimized sequential writes.
+-   After a summary of conventions used in describing the netCDF
+    interfaces, the rest of this chapter presents a detailed description
+    of the interfaces for these operations.

+2.2 NetCDF Library Interface Descriptions {.section}
+-----------------------------------------
+
+Each interface description for a particular netCDF function in this and
+later chapters contains:
+
+-   a description of the purpose of the function;
+-   a Fortran 90 interface block that presents the type and order of the
+    formal parameters to the function;
+-   a description of each formal parameter in the C interface;
+-   a list of possible error conditions; and
+-   an example of a Fortran 90 program fragment calling the netCDF
+    function (and perhaps other netCDF functions).
+
+The examples follow a simple convention for error handling, always
+checking the error status returned from each netCDF function call and
+calling a handle\_error function in case an error was detected. For an
+example of such a function, see Section 5.2 "Get error message
+corresponding to error status: nf90\_strerror".

+
+2.3 NF90\_STRERROR {.section}
+------------------
+
+The function NF90\_STRERROR returns a static reference to an error
+message string corresponding to an integer netCDF error status or to a
+system error number, presumably returned by a previous call to some
+other netCDF function. The list of netCDF error status codes is
+available in the appropriate include file for each language binding.
+
+Usage {.heading}

+
+Errors {.heading}
+------
+
+If you provide an invalid integer error status that does not correspond
+to any netCDF error message or or to any system error message (as
+understood by the system strerror function), NF90\_STRERROR returns a
+string indicating that there is no such error status.
+
+Example {.heading}
+-------
+
+Here is an example of a simple error handling function that uses
+NF90\_STRERROR to print the error message corresponding to the netCDF
+error status returned from any netCDF function call and then exit:

++--------------------------------------+--------------------------------------+
+
+ `path`
+
+:   The file name of the new netCDF dataset.
+
+ `cmode`
+
+:   The creation mode flag. The following flags are available:
+    NF90\_CLOBBER, NF90\_NOCLOBBER, NF90\_SHARE, NF90\_64BIT\_OFFSET,
+    NF90\_NETCDF4, and NF90\_CLASSIC\_MODEL. (NF90\_HDF5 is deprecated,
+    use NF90\_NETCDF4 instead).
+
+    A zero value (defined for convenience as NF90\_CLOBBER) specifies:
+    overwrite any existing dataset with the same file name, and buffer
+    and cache accesses for efficiency. The dataset will be in netCDF
+    classic format. See [(netcdf)NetCDF Classic Format
+    Limitations](netcdf.html#NetCDF-Classic-Format-Limitations) section
+    ‘NetCDF Classic Format Limitations’ in NetCDF Users’ Guide.
+
+    Setting NF90\_NOCLOBBER means you do not want to clobber (overwrite)
+    an existing dataset; an error (NF90\_EEXIST) is returned if the
+    specified dataset already exists.
+
+    The NF90\_SHARE flag is appropriate when one process may be writing
+    the dataset and one or more other processes reading the dataset
+    concurrently; it means that dataset accesses are not buffered and
+    caching is limited. Since the buffering scheme is optimized for
+    sequential access, programs that do not access data sequentially may
+    see some performance improvement by setting the NF90\_SHARE flag.
+    (This only applies to netCDF-3 classic or 64-bit offset files.)
+
+    Setting NF90\_64BIT\_OFFSET causes netCDF to create a 64-bit offset
+    format file, instead of a netCDF classic format file. The 64-bit
+    offset format imposes far fewer restrictions on very large (i.e.
+    over 2 GB) data files. See [(netcdf)Large File
+    Support](netcdf.html#Large-File-Support) section ‘Large File
+    Support’ in NetCDF Users’ Guide.
+
+    Setting the NF90\_NETCDF4 flag causes netCDF to create a
+    netCDF-4/HDF5 format output file.
+
+    Oring the NF90\_CLASSIC\_MODEL flag with the NF90\_NETCDF4 flag
+    causes the resulting netCDF-4/HDF5 file to restrict itself to the
+    classic model - none of the new netCDF-4 data model features, such
+    as groups or user-defined types, are allowed in such a file.
+
+ `ncid`
+
+:   Returned netCDF ID.
+
+The following optional arguments allow additional performance tuning.
+
+ `initialsize`
+
+:   The initial size of the file (in bytes) at creation time. A value of
+    0 causes the file size to be computed when nf90\_enddef is called.
+    This is ignored for NetCDF-4/HDF5 files.
+
+ `bufrsize`
+
+:   Controls a space versus time trade-off, memory allocated in the
+    netcdf library versus number of system calls. Because of internal
+    requirements, the value may not be set to exactly the
+    value requested. The actual value chosen is returned.
+
+    The library chooses a system-dependent default value if
+    NF90\_SIZEHINT\_DEFAULT is supplied as input. If the "preferred I/O
+    block size" is available from the stat() system call as member
+    st\_blksize this value is used. Lacking that, twice the system
+    pagesize is used. Lacking a call to discover the system pagesize,
+    the default bufrsize is set to 8192 bytes.
+
+    The bufrsize is a property of a given open netcdf descriptor ncid,
+    it is not a persistent property of the netcdf dataset.
+
+    This is ignored for NetCDF-4/HDF5 files.
+
+ `cache_size`
+
+:   If the cache\_size is provided when creating a netCDF-4/HDF5 file,
+    it will be used instead of the default (32000000) as the size, in
+    bytes, of the HDF5 chunk cache.
+
+ `cache_nelems`
+
+:   If cache\_nelems is provided when creating a netCDF-4/HDF5 file, it
+    will be used instead of the default (1000) as the maximum number of
+    elements in the HDF5 chunk cache.
+
+ `cache_premtion`
+
+:   If cache\_preemption is provided when creating a netCDF-4/HDF5 file,
+    it will be used instead of the default (0.75) as the preemption
+    value for the HDF5 chunk cache.
+
+ `comm`
+
+:   If the comm and info parameters are provided the file is created and
+    opened for parallel I/O. Set the comm parameter to the MPI
+    communicator (of type MPI\_Comm). If this parameter is provided the
+    info parameter must also be provided.
+
+ `info`
+
+:   If the comm and info parameters are provided the file is created and
+    opened for parallel I/O. Set the comm parameter to the MPI
+    information value (of type MPI\_Info). If this parameter is provided
+    the comm parameter must also be provided.
+
+Errors {.heading}
+------
+
+NF90\_CREATE returns the value NF90\_NOERR if no errors occurred.
+Possible causes of errors include:
+
+-   Passing a dataset name that includes a directory that does
+    not exist.
+-   Specifying a dataset name of a file that exists and also
+    specifying NF90\_NOCLOBBER.
+-   Specifying a meaningless value for the creation mode.
+-   Attempting to create a netCDF dataset in a directory where you don’t
+    have permission to create files.

+    process may be writing the dataset and one or more other processes
+    reading the dataset concurrently (note that this is not the same as
+    parallel I/O); it means that dataset accesses are not buffered and
+    caching is limited. Since the buffering scheme is optimized for
+    sequential access, programs that do not access data sequentially may
+    see some performance improvement by setting the NF90\_SHARE flag.
+
+ `ncid`
+
+:   Returned netCDF ID.
+
+The following optional argument allows additional performance tuning.
+
+ `bufrsize`
+
+:   This parameter applies only when opening classic format or 64-bit
+    offset files. It is ignored for netCDF-4/HDF5 files.
+
+    It Controls a space versus time trade-off, memory allocated in the
+    netcdf library versus number of system calls. Because of internal
+    requirements, the value may not be set to exactly the
+    value requested. The actual value chosen is returned.
+
+    The library chooses a system-dependent default value if
+    NF90\_SIZEHINT\_DEFAULT is supplied as input. If the "preferred I/O
+    block size" is available from the stat() system call as member
+    st\_blksize this value is used. Lacking that, twice the system
+    pagesize is used. Lacking a call to discover the system pagesize,
+    the default bufrsize is set to 8192 bytes.
+
+    The bufrsize is a property of a given open netcdf descriptor ncid,
+    it is not a persistent property of the netcdf dataset.
+
+ `cache_size`
+
+:   If the cache\_size is provided when opening a netCDF-4/HDF5 file, it
+    will be used instead of the default (32000000) as the size, in
+    bytes, of the HDF5 chunk cache.
+
+ `cache_nelems`
+
+:   If cache\_nelems is provided when opening a netCDF-4/HDF5 file, it
+    will be used instead of the default (1000) as the maximum number of
+    elements in the HDF5 chunk cache.
+
+ `cache_premtion`
+
+:   If cache\_preemption is provided when opening a netCDF-4/HDF5 file,
+    it will be used instead of the default (0.75) as the preemption
+    value for the HDF5 chunk cache.
+
+ `comm`
+
+:   If the comm and info parameters are provided the file is opened for
+    parallel I/O. Set the comm parameter to the MPI communicator (of
+    type MPI\_Comm). If this parameter is provided the info parameter
+    must also be provided.
+
+ `info`
+
+:   If the comm and info parameters are provided the file is opened for
+    parallel I/O. Set the comm parameter to the MPI information value
+    (of type MPI\_Info). If this parameter is provided the comm
+    parameter must also be provided.
+
+Errors {.heading}

+
+NF90\_OPEN returns the value NF90\_NOERR if no errors occurred.

+2.8 NF90\_ENDDEF {.section}
+----------------
+
+The function NF90\_ENDDEF takes an open netCDF dataset out of define
+mode. The changes made to the netCDF dataset while it was in define mode
+are checked and committed to disk if no problems occurred. Non-record
+variables may be initialized to a "fill value" as well (see section
+[NF90\_SET\_FILL](#NF90_005fSET_005fFILL)). The netCDF dataset is then
+placed in data mode, so variable data can be read or written.
+
+This call may involve copying data under some circumstances. For a more
+extensive discussion See [(netcdf)File Structure and
+Performance](netcdf.html#File-Structure-and-Performance) section ‘File
+Structure and Performance’ in NetCDF Users Guide.

++--------------------------------------+--------------------------------------+
+
+ `ncid`
+
+:   NetCDF ID, from a previous call to NF90\_OPEN or NF90\_CREATE.
+
+The following arguments allow additional performance tuning. Note: these
+arguments expose internals of the netcdf version 1 file format, and may
+not be available in future netcdf implementations.
+
+The current netcdf file format has three sections: the "header" section,
+the data section for fixed size variables, and the data section for
+variables which have an unlimited dimension (record variables). The
+header begins at the beginning of the file. The index (offset) of the
+beginning of the other two sections is contained in the header.
+Typically, there is no space between the sections. This causes copying
+overhead to accrue if one wishes to change the size of the sections, as
+may happen when changing the names of things, text attribute values,
+adding attributes or adding variables. Also, for buffered i/o, there may
+be advantages to aligning sections in certain ways.
+
+The minfree parameters allow one to control costs of future calls to
+nf90\_redef or nf90\_enddef by requesting that some space be available
+at the end of the section. The default value for both h\_minfree and
+v\_minfree is 0.
+
+The align parameters allow one to set the alignment of the beginning of
+the corresponding sections. The beginning of the section is rounded up
+to an index which is a multiple of the align parameter. The flag value
+NF90\_ALIGN\_CHUNK tells the library to use the bufrsize (see above) as
+the align parameter. The default value for both v\_align and r\_align is
+4 bytes.
+
+ `h_minfree`
+
+:   Size of the pad (in bytes) at the end of the "header" section.
+
+ `v_minfree`
+
+:   Size of the pad (in bytes) at the end of the data section for fixed
+    size variables.
+
+ `v_align`
+
+:   The alignment of the beginning of the data section for fixed
+    size variables.
+
+ `r_align`
+
+:   The alignment of the beginning of the data section for variables
+    which have an unlimited dimension (record variables).
+
+Errors {.heading}
+------
+
+NF90\_ENDDEF returns the value NF90\_NOERR if no errors occurred.
+Otherwise, the returned status indicates an error. Possible causes of
+errors include:
+
+-   The specified netCDF dataset is not in define mode.
+-   The specified netCDF ID does not refer to an open netCDF dataset.
+-   The size of one or more variables exceed the size constraints for
+    whichever variant of the file format is in use). See [(netcdf)Large
+    File Support](netcdf.html#Large-File-Support) section ‘Large File
+    Support’ in The NetCDF Users Guide.

+2.9 NF90\_CLOSE {.section}
+---------------
+
+The function NF90\_CLOSE closes an open netCDF dataset. If the dataset
+is in define mode, NF90\_ENDDEF will be called before closing. (In this
+case, if NF90\_ENDDEF returns an error, NF90\_ABORT will automatically

+2.10 NF90\_INQUIRE Family {.section}
+-------------------------
+
+The NF90\_INQUIRE subroutine returns information about an open netCDF
+dataset, given its netCDF ID. The subroutine can be called from either
+define mode or data mode, and returns values for any or all of the
+following: the number of dimensions, the number of variables, the number
+of global attributes, and the dimension ID of the dimension defined with
+unlimited length, if any. An additional function, NF90\_INQ\_FORMAT,
+returns the (rarely needed) format version.
+
+No I/O is performed when NF90\_INQUIRE is called, since the required
+information is available in memory for each open netCDF dataset.

+2.11 NF90\_SYNC {.section}
+---------------
+
+The function NF90\_SYNC offers a way to synchronize the disk copy of a
+netCDF dataset with in-memory buffers. There are two reasons you might
+want to synchronize after writes:
+
+-   To minimize data loss in case of abnormal termination, or
+-   To make data available to other processes for reading immediately
+    after it is written. But note that a process that already had the
+    dataset open for reading would not see the number of records
+    increase when the writing process calls NF90\_SYNC; to accomplish
+    this, the reading process must call NF90\_SYNC.
+
+This function is backward-compatible with previous versions of the
+netCDF library. The intent was to allow sharing of a netCDF dataset
+among multiple readers and one writer, by having the writer call
+NF90\_SYNC after writing and the readers call NF90\_SYNC before each
+read. For a writer, this flushes buffers to disk. For a reader, it makes
+sure that the next read will be from disk rather than from previously
+cached buffers, so that the reader will see changes made by the writing
+process (e.g., the number of records written) without having to close
+and reopen the dataset. If you are only accessing a small amount of
+data, it can be expensive in computer resources to always synchronize to
+disk after every write, since you are giving up the benefits of
+buffering.
+
+An easier way to accomplish sharing (and what is now recommended) is to
+have the writer and readers open the dataset with the NF90\_SHARE flag,
+and then it will not be necessary to call NF90\_SYNC at all. However,
+the NF90\_SYNC function still provides finer granularity than the
+NF90\_SHARE flag, if only a few netCDF accesses need to be synchronized
+among processes.
+
+It is important to note that changes to the ancillary data, such as
+attribute values, are not propagated automatically by use of the
+NF90\_SHARE flag. Use of the NF90\_SYNC function is still required for
+this purpose.
+
+Sharing datasets when the writer enters define mode to change the data
+schema requires extra care. In previous releases, after the writer left
+define mode, the readers were left looking at an old copy of the
+dataset, since the changes were made to a new copy. The only way readers
+could see the changes was by closing and reopening the dataset. Now the
+changes are made in place, but readers have no knowledge that their
+internal tables are now inconsistent with the new dataset schema. If
+netCDF datasets are shared across redefinition, some mechanism external
+to the netCDF library must be provided that prevents access by readers
+during redefinition and causes the readers to call NF90\_SYNC before any
+subsequent access.
+
+When calling NF90\_SYNC, the netCDF dataset must be in data mode. A
+netCDF dataset in define mode is synchronized to disk only when
+NF90\_ENDDEF is called. A process that is reading a netCDF dataset that
+another process is writing may call NF90\_SYNC to get updated with the
+changes made to the data by the writing process (e.g., the number of
+records written), without having to close and reopen the dataset.
+
+Data is automatically synchronized to disk when a netCDF dataset is
+closed, or whenever you leave define mode.

+2.12 NF90\_ABORT {.section}
+----------------
+
+You no longer need to call this function, since it is called
+automatically by NF90\_CLOSE in case the dataset is in define mode and
+something goes wrong with committing the changes. The function
+NF90\_ABORT just closes the netCDF dataset, if not in define mode. If
+the dataset is being created and is still in define mode, the dataset is
+deleted. If define mode was entered by a call to NF90\_REDEF, the netCDF
+dataset is restored to its state before definition mode was entered and
+the dataset is closed.

+2.13 NF90\_SET\_FILL {.section}
+--------------------
+
+This function is intended for advanced usage, to optimize writes under
+some circumstances described below. The function NF90\_SET\_FILL sets
+the fill mode for a netCDF dataset open for writing and returns the
+current fill mode in a return parameter. The fill mode can be specified
+as either NF90\_FILL or NF90\_NOFILL. The default behavior corresponding
+to NF90\_FILL is that data is pre-filled with fill values, that is fill
+values are written when you create non-record variables or when you
+write a value beyond data that has not yet been written. This makes it
+possible to detect attempts to read data before it was written. See
+section [Fill Values](#Fill-Values), for more information on the use of
+fill values. See [(netcdf)Attribute
+Conventions](netcdf.html#Attribute-Conventions) section ‘Attribute
+Conventions’ in The NetCDF Users Guide, for information about how to
+define your own fill values.
+
+The behavior corresponding to NF90\_NOFILL overrides the default
+behavior of prefilling data with fill values. This can be used to
+enhance performance, because it avoids the duplicate writes that occur
+when the netCDF library writes fill values that are later overwritten
+with data.
+
+A value indicating which mode the netCDF dataset was already in is
+returned. You can use this value to temporarily change the fill mode of
+an open netCDF dataset and then restore it to the previous mode.
+
+After you turn on NF90\_NOFILL mode for an open netCDF dataset, you must
+be certain to write valid data in all the positions that will later be
+read. Note that nofill mode is only a transient property of a netCDF
+dataset open for writing: if you close and reopen the dataset, it will
+revert to the default behavior. You can also revert to the default
+behavior by calling NF90\_SET\_FILL again to explicitly set the fill
+mode to NF90\_FILL.
+
+There are three situations where it is advantageous to set nofill mode:
+
+1.  Creating and initializing a netCDF dataset. In this case, you should
+    set nofill mode before calling NF90\_ENDDEF and then write
+    completely all non-record variables and the initial records of all
+    the record variables you want to initialize.
+2.  Extending an existing record-oriented netCDF dataset. Set nofill
+    mode after opening the dataset for writing, then append the
+    additional records to the dataset completely, leaving no intervening
+    unwritten records.
+3.  Adding new variables that you are going to initialize to an existing
+    netCDF dataset. Set nofill mode before calling NF90\_ENDDEF then
+    write all the new variables completely.
+
+If the netCDF dataset has an unlimited dimension and the last record was
+written while in nofill mode, then the dataset may be shorter than if
+nofill mode was not set, but this will be completely transparent if you
+access the data only through the netCDF interfaces.
+
+The use of this feature may not be available (or even needed) in future
+releases. Programmers are cautioned against heavy reliance upon this
+feature.

+3. Groups {.chapter}
+=========
+
+NetCDF-4 added support for hierarchical groups within netCDF datasets.
+
+Groups are identified with a ncid, which identifies both the open file,
+and the group within that file. When a file is opened with NF90\_OPEN or
+NF90\_CREATE, the ncid for the root group of that file is provided.
+Using that as a starting point, users can add new groups, or list and
+navigate existing groups.
+
+All netCDF calls take a ncid which determines where the call will take
+its action. For example, the NF90\_DEF\_VAR function takes a ncid as its
+first parameter. It will create a variable in whichever group its ncid
+refers to. Use the root ncid provided by NF90\_CREATE or NF90\_OPEN to
+create a variable in the root group. Or use NF90\_DEF\_GRP to create a
+group and use its ncid to define a variable in the new group.
+
+Variable are only visible in the group in which they are defined. The
+same applies to attributes. “Global” attributes are defined in whichever
+group is refered to by the ncid.
+
+Dimensions are visible in their groups, and all child groups.
+
+Group operations are only permitted on netCDF-4 files - that is, files
+created with the HDF5 flag in nf90\_create. (see section
+[NF90\_CREATE](#NF90_005fCREATE)). Groups are not compatible with the
+netCDF classic data model, so files created with the
+NF90\_CLASSIC\_MODEL file cannot contain groups (except the root group).

+4.1 Dimensions Introduction {.section}
+---------------------------
+
+Dimensions for a netCDF dataset are defined when it is created, while
+the netCDF dataset is in define mode. Additional dimensions may be added
+later by reentering define mode. A netCDF dimension has a name and a
+length. At most one dimension in a netCDF dataset can have the unlimited
+length, which means variables using this dimension can grow along this
+dimension.
+
+There is a suggested limit (512) to the number of dimensions that can be
+defined in a single netCDF dataset. The limit is the value of the
+constant NF90\_MAX\_DIMS. The purpose of the limit is to make writing
+generic applications simpler. They need only provide an array of
+NF90\_MAX\_DIMS dimensions to handle any netCDF dataset. The
+implementation of the netCDF library does not enforce this advisory
+maximum, so it is possible to use more dimensions, if necessary, but
+netCDF utilities that assume the advisory maximums may not be able to
+handle the resulting netCDF datasets.
+
+Ordinarily, the name and length of a dimension are fixed when the
+dimension is first defined. The name may be changed later, but the
+length of a dimension (other than the unlimited dimension) cannot be
+changed without copying all the data to a new netCDF dataset with a
+redefined dimension length.
+
+A netCDF dimension in an open netCDF dataset is referred to by a small
+integer called a dimension ID. In the Fortran 90 interface, dimension
+IDs are 1, 2, 3, ..., in the order in which the dimensions were defined.
+
+Operations supported on dimensions are:
+
+-   Create a dimension, given its name and length.
+-   Get a dimension ID from its name.
+-   Get a dimension’s name and length from its ID.
+-   Rename a dimension.

+4.2 NF90\_DEF\_DIM {.section}
+------------------
+
+The function NF90\_DEF\_DIM adds a new dimension to an open netCDF
+dataset in define mode. It returns (as an argument) a dimension ID,
+given the netCDF ID, the dimension name, and the dimension length. At
+most one unlimited length dimension, called the record dimension, may be
+defined for each netCDF dataset.

+Errors {.heading}
+------
+
+NF90\_DEF\_DIM returns the value NF90\_NOERR if no errors occurred.
+Otherwise, the returned status indicates an error. Possible causes of
+errors include:
+
+-   The netCDF dataset is not in definition mode.
+-   The specified dimension name is the name of another
+    existing dimension.
+-   The specified length is not greater than zero.
+-   The specified length is unlimited, but there is already an unlimited
+    length dimension defined for this netCDF dataset.
+-   The specified netCDF ID does not refer to an open netCDF dataset.

+4.5 NF90\_RENAME\_DIM {.section}
+---------------------
+
+The function NF90\_RENAME\_DIM renames an existing dimension in a netCDF
+dataset open for writing. If the new name is longer than the old name,
+the netCDF dataset must be in define mode. You cannot rename a dimension
+to have the same name as another dimension.

++--------------------------------------+--------------------------------------+
+
+ `ncid`
+
+:   NetCDF ID, from a previous call to NF90\_OPEN or NF90\_CREATE.
+
+ `dimid`
+
+:   Dimension ID, from a previous call to NF90\_INQ\_DIMID
+    or NF90\_DEF\_DIM.
+
+ `name`
+
+:   New dimension name.
+
+Errors {.heading}
+------
+
+NF90\_RENAME\_DIM returns the value NF90\_NOERR if no errors occurred.
+Otherwise, the returned status indicates an error. Possible causes of
+errors include:
+
+-   The new name is the name of another dimension.
+-   The dimension ID is invalid for the specified netCDF dataset.
+-   The specified netCDF ID does not refer to an open netCDF dataset.
+-   The new name is longer than the old name and the netCDF dataset is
+    not in define mode.

+
+5.1 User Defined Types Introduction {.section}
+-----------------------------------
+
+NetCDF-4 has added support for four different user defined data types.
+
+ `compound type`
+
+:   Like a C struct, a compound type is a collection of types, including
+    other user defined types, in one package.
+
+ `variable length array type`
+
+:   The variable length array may be used to store ragged arrays.
+
+ `opaque type`
+
+:   This type has only a size per element, and no other
+    type information.
+
+ `enum type`
+
+:   Like an enumeration in C, this type lets you assign text values to
+    integer values, and store the integer values.
+
+Users may construct user defined type with the various NF90\_DEF\_\*
+functions described in this section. They may learn about user defined
+types by using the NF90\_INQ\_ functions defined in this section.
+
+Once types are constructed, define variables of the new type with
+NF90\_DEF\_VAR (see section [Create a Variable:
+`NF90_DEF_VAR`](#NF90_005fDEF_005fVAR)). Write to them with
+NF90\_PUT\_VAR (see section [Writing Data Values:
+NF90\_PUT\_VAR](#NF90_005fPUT_005fVAR)). Read data of user-defined type
+with NF90\_GET\_VAR (see section [Reading Data Values:
+NF90\_GET\_VAR](#NF90_005fGET_005fVAR)).
+
+Create attributes of the new type with NF90\_PUT\_ATT (see section
+[Create an Attribute: NF90\_PUT\_ATT](#NF90_005fPUT_005fATT)). Read
+attributes of the new type with NF90\_GET\_ATT (see section [Get
+Attribute’s Values: NF90\_GET\_ATT](#NF90_005fGET_005fATT)).

+5.6 Compound Types Introduction {.section}
+-------------------------------
+
+NetCDF-4 added support for compound types, which allow users to
+construct a new type - a combination of other types, like a C struct.
+
+Compound types are not supported in classic or 64-bit offset format
+files.
+
+To write data in a compound type, first use nf90\_def\_compound to
+create the type, multiple calls to nf90\_insert\_compound to add to the
+compound type, and then write data with the appropriate nf90\_put\_var1,
+nf90\_put\_vara, nf90\_put\_vars, or nf90\_put\_varm call.
+
+To read data written in a compound type, you must know its structure.
+Use the NF90\_INQ\_COMPOUND functions to learn about the compound type.
+
+In Fortran a character buffer must be used for the compound data. The
+user must read the data from within that buffer in the same way that the
+C compiler which compiled netCDF would store the structure.
+
+The use of compound types introduces challenges and portability issues
+for Fortran users.

+### 5.6.1 Creating a Compound Type: NF90\_DEF\_COMPOUND {.subsection}
+
+Create a compound type. Provide an ncid, a name, and a total size (in
+bytes) of one element of the completed compound type.
+
+After calling this function, fill out the type with repeated calls to
+NF90\_INSERT\_COMPOUND (see section [Inserting a Field into a Compound
+Type: NF90\_INSERT\_COMPOUND](#NF90_005fINSERT_005fCOMPOUND)). Call
+NF90\_INSERT\_COMPOUND once for each field you wish to insert into the
+compound type.
+
+Note that there does not seem to be a fully portable way to read such
+types into structures in Fortran 90 (and there are no structures in
+Fortran 77). Dozens of top-notch programmers are swarming over this
+problem in a sub-basement of Unidata’s giant underground bunker in
+Wyoming.
+
+Fortran users may use character buffers to read and write compound
+types. User are invited to try classic Fortran features such as the
+equivilence and the common block statment.

+5.7 Variable Length Array Introduction {.section}
+--------------------------------------
+
+NetCDF-4 added support for a variable length array type. This is not
+supported in classic or 64-bit offset files, or in netCDF-4 files which
+were created with the NF90\_CLASSIC\_MODEL flag.
+
+A variable length array is represented in C as a structure from HDF5,
+the nf90\_vlen\_t structure. It contains a len member, which contains
+the length of that array, and a pointer to the array.
+
+So an array of VLEN in C is an array of nc\_vlen\_t structures. The only
+way to handle this in Fortran is with a character buffer sized correctly
+for the platform.
+
+VLEN arrays are handled differently with respect to allocation of
+memory. Generally, when reading data, it is up to the user to malloc
+(and subsequently free) the memory needed to hold the data. It is up to
+the user to ensure that enough memory is allocated.
+
+With VLENs, this is impossible. The user cannot know the size of an
+array of VLEN until after reading the array. Therefore when reading VLEN
+arrays, the netCDF library will allocate the memory for the data within
+each VLEN.
+
+It is up to the user, however, to eventually free this memory. This is
+not just a matter of one call to free, with the pointer to the array of
+VLENs; each VLEN contains a pointer which must be freed.

+### 5.7.3 Releasing Memory for a Variable Length Array (VLEN) Type: NF90\_FREE\_VLEN {.subsection}
+
+When a VLEN is read into user memory from the file, the HDF5 library
+performs memory allocations for each of the variable length arrays
+contained within the VLEN structure. This memory must be freed by the
+user to avoid memory leaks.
+
+This violates the normal netCDF expectation that the user is responsible
+for all memory allocation. But, with VLEN arrays, the underlying HDF5
+library allocates the memory for the user, and the user is responsible
+for deallocating that memory.

+5.8 Opaque Type Introduction {.section}
+----------------------------
+
+NetCDF-4 added support for the opaque type. This is not supported in
+classic or 64-bit offset files.
+
+The opaque type is a type which is a collection of objects of a known
+size. (And each object is the same size). Nothing is known to netCDF
+about the contents of these blobs of data, except their size in bytes,
+and the name of the type.
+
+To use an opaque type, first define it with [Creating Opaque Types:
+NF90\_DEF\_OPAQUE](#NF90_005fDEF_005fOPAQUE). If encountering an enum
+type in a new data file, use [Learn About an Opaque Type:
+NF90\_INQ\_OPAQUE](#NF90_005fINQ_005fOPAQUE) to learn its name and size.

+### 5.9.1 Creating a Enum Type: NF90\_DEF\_ENUM {.subsection}
+
+Create an enum type. Provide an ncid, a name, and a base integer type.
+
+After calling this function, fill out the type with repeated calls to
+NF90\_INSERT\_ENUM (see section [Inserting a Field into a Enum Type:
+NF90\_INSERT\_ENUM](#NF90_005fINSERT_005fENUM)). Call NF90\_INSERT\_ENUM
+once for each value you wish to make part of the enumeration.

+6.1 Variables Introduction {.section}
+--------------------------
+
+Variables for a netCDF dataset are defined when the dataset is created,
+while the netCDF dataset is in define mode. Other variables may be added
+later by reentering define mode. A netCDF variable has a name, a type,
+and a shape, which are specified when it is defined. A variable may also
+have values, which are established later in data mode.
+
+Ordinarily, the name, type, and shape are fixed when the variable is
+first defined. The name may be changed, but the type and shape of a
+variable cannot be changed. However, a variable defined in terms of the
+unlimited dimension can grow without bound in that dimension.
+
+A netCDF variable in an open netCDF dataset is referred to by a small
+integer called a variable ID.
+
+Variable IDs reflect the order in which variables were defined within a
+netCDF dataset. Variable IDs are 1, 2, 3,..., in the order in which the
+variables were defined. A function is available for getting the variable
+ID from the variable name and vice-versa.
+
+Attributes (see [Attributes](#Attributes)) may be associated with a
+variable to specify such properties as units.
+
+Operations supported on variables are:
+
+-   Create a variable, given its name, data type, and shape.
+-   Get a variable ID from its name.
+-   Get a variable’s name, data type, shape, and number of attributes
+    from its ID.
+-   Put a data value into a variable, given variable ID, indices,
+    and value.
+-   Put an array of values into a variable, given variable ID, corner
+    indices, edge lengths, and a block of values.
+-   Put a subsampled or mapped array-section of values into a variable,
+    given variable ID, corner indices, edge lengths, stride vector,
+    index mapping vector, and a block of values.
+-   Get a data value from a variable, given variable ID and indices.
+-   Get an array of values from a variable, given variable ID, corner
+    indices, and edge lengths.
+-   Get a subsampled or mapped array-section of values from a variable,
+    given variable ID, corner indices, edge lengths, stride vector, and
+    index mapping vector.
+-   Rename a variable.

+6.2 Language Types Corresponding to netCDF external data types {.section}
+--------------------------------------------------------------
+
+The following table gives the netCDF external data types and the
+corresponding type constants for defining variables in the FORTRAN
+interface:
+
+  -------- ---------------------- ------
+  Type     FORTRAN API Mnemonic   Bits
+  byte     NF90\_BYTE             8
+  char     NF90\_CHAR             8
+  short    NF90\_SHORT            16
+  int      NF90\_INT              32
+  float    NF90\_FLOAT            32
+  double   NF90\_DOUBLE           64
+  -------- ---------------------- ------
+
+The first column gives the netCDF external data type, which is the same
+as the CDL data type. The next column gives the corresponding Fortran 90
+parameter for use in netCDF functions (the parameters are defined in the
+netCDF Fortran 90 module netcdf.f90). The last column gives the number
+of bits used in the external representation of values of the
+corresponding type.
+
+Note that there are no netCDF types corresponding to 64-bit integers or
+to characters wider than 8 bits in the current version of the netCDF
+library.

+
+6.3 Create a Variable: `NF90_DEF_VAR` {.section}
+-------------------------------------
+
+The function NF90\_DEF\_VAR adds a new variable to an open netCDF
+dataset in define mode. It returns (as an argument) a variable ID, given
+the netCDF ID, the variable name, the variable type, the number of
+dimensions, and a list of the dimension IDs.
+
+Optional arguments allow additional settings for variables in
+netCDF-4/HDF5 files. These parameters allow data compression and control
+of the layout of the data on disk for performance tuning. These
+parameters may also be used to set the chunk sizes to get chunked
+storage, or to set the contiguous flag to get contiguous storage.
+
+Variables that make use of one or more unlimited dimensions,
+compression, or checksums must use chunking. Such variables are created
+with default chunk sizes of 1 for each unlimited dimension and the
+dimension length for other dimensions, except that if the resulting
+chunks are too large, the default chunk sizes for non-record dimensions
+are reduced.
+
+All parameters after the varid are optional, and only supported if
+netCDF was built with netCDF-4 features enabled, and if the variable is
+in a netCDF-4/HDF5 file.

++--------------------------------------+--------------------------------------+
+
+ `ncid`
+
+:   NetCDF ID, from a previous call to NF90\_OPEN or NF90\_CREATE.
+
+ `name`
+
+:   Variable name.
+
+ `xtype`
+
+:   One of the set of predefined netCDF external data types. The type of
+    this parameter, NF90\_TYPE, is defined in the netCDF header file.
+    The valid netCDF external data types are NF90\_BYTE, NF90\_CHAR,
+    NF90\_SHORT, NF90\_INT, NF90\_FLOAT, and NF90\_DOUBLE. If the file
+    is a NetCDF-4/HDF5 file, the additional types NF90\_UBYTE,
+    NF90\_USHORT, NF90\_UINT, NF90\_INT64, NF90\_UINT64, and
+    NF90\_STRING may be used, as well as a user defined type ID.
+
+ `dimids`
+
+:   Scalar or vector of dimension IDs corresponding to the
+    variable dimensions. For example, a vector of 2 dimension IDs
+    specifies a 2-dimensional matrix.
+
+    If an integer is passed for this parameter, a 1-D variable
+    is created.
+
+    If this parameter is not passed (or is a 1D array of size zero) it
+    means the variable is a scalar with no dimensions.
+
+    For classic data model files, if the ID of the unlimited dimension
+    is included, it must be first. In expanded model netCDF4/HDF5 files,
+    there may be any number of unlimited dimensions, and they may be
+    used in any element of the dimids array.
+
+    This argument is optional, and if absent specifies a scalar with
+    no dimensions.
+
+ `varid`
+
+:   Returned variable ID.
+
+ `storage`
+
+:   If NF90\_CONTIGUOUS, then contiguous storage is used for
+    this variable. Variables that use deflation, shuffle filter, or
+    checksums, or that have one or more unlimited dimensions cannot use
+    contiguous storage.
+
+    If NF90\_CHUNKED, then chunked storage is used for this variable.
+    Chunk sizes may be specified with the chunksizes parameter. Default
+    sizes will be used if chunking is required and this function is
+    not called.
+
+    By default contiguous storage is used for fix-sized variables when
+    conpression, chunking, shuffle, and checksums are not used.
+
+ `chunksizes`
+
+:   An array of chunk number of elements. This array has the number of
+    elements along each dimension of the data chunk. The array must have
+    the one chunksize for each dimension in the variable.
+
+    The total size of a chunk must be less than 4 GiB. That is, the
+    product of all chunksizes and the size of the data (or the size of
+    nc\_vlen\_t for VLEN types) must be less than 4 GiB. (This is a very
+    large chunk size in any case.)
+
+    If not provided, but chunked data are needed, then default
+    chunksizes will be chosen. For more information see [The NetCDF
+    Users Guide: (netcdf)Chunking](netcdf.html#Chunking) section
+    ‘Chunking’ in The NetCDF Users Guide.
+
+ `shuffle`
+
+:   If non-zero, turn on the shuffle filter.
+
+ `deflate_level`
+
+:   If the deflate parameter is non-zero, set the deflate level to
+    this value. Must be between 1 and 9.
+
+ `fletcher32`
+
+:   Set to true to turn on fletcher32 checksums for this variable.
+
+ `endianness`
+
+:   Set to NF90\_ENDIAN\_LITTLE for little-endian format,
+    NF90\_ENDIAN\_BIG for big-endian format, and NF90\_ENDIAN\_NATIVE
+    (the default) for the native endianness of the platform.
+
+ `cache_size`
+
+:   The size of the per-variable cache in MegaBytes.
+
+ `cache_nelems`
+
+:   The number slots in the per-variable chunk cache (should be a prime
+    number larger than the number of chunks in the cache).
+
+ `cache_preemption`
+
+:   The preemtion value must be between 0 and 100 inclusive and
+    indicates how much chunks that have been fully read are favored
+    for preemption. A value of zero means fully read chunks are treated
+    no differently than other chunks (the preemption is strictly LRU)
+    while a value of 100 means fully read chunks are always preempted
+    before other chunks.
+
+Return Codes {.heading}
+------------
+
+NF90\_DEF\_VAR returns the value NF90\_NOERR if no errors occurred.
+Otherwise, the returned status indicates an error.
+
+-   NF90\_EBADNAME The specified variable name is the name of another
+    existing variable.
+-   NF90\_EBADTYPE The specified type is not a valid netCDF type.
+-   NF90\_EMAXDIMS The specified number of dimensions is negative or
+    more than the constant NF90\_MAX\_VAR\_DIMS, the maximum number of
+    dimensions permitted for a netCDF variable. (Does not apply to
+    netCDF-4/HDF5 files unless they were created with the
+    CLASSIC\_MODE flag.)
+-   NF90\_EBADDIM One or more of the dimension IDs in the list of
+    dimensions is not a valid dimension ID for the netCDF dataset.
+-   NF90\_EMAXVARS The number of variables would exceed the constant
+    NF90\_MAX\_VARS, the maximum number of variables permitted in a
+    classic netCDF dataset. (Does not apply to netCDF-4/HDF5 files
+    unless they were created with the CLASSIC\_MODE flag.)
+-   NF90\_BADID The specified netCDF ID does not refer to an open
+    netCDF dataset.
+-   NF90\_ENOTNC4 NetCDF-4 operation attempted on a files that is not a
+    netCDF-4/HDF5 file. Only variables in NetCDF-4/HDF5 files may use
+    compression, chunking, and endianness control.
+-   NF90\_ENOTVAR Can’t find this variable.
+-   NF90\_EINVAL Invalid input. This may be because contiguous storage
+    is requested for a variable that has compression, checksums,
+    chunking, or one or more unlimited dimensions.
+-   NF90\_ELATEDEF This variable has already been the subject of a
+    NF90\_ENDDEF call. Once enddef has been called, it is impossible to
+    set the chunking for a variable. (In netCDF-4/HDF5 files
+    NF90\_ENDDEF will be called automatically for any data read
+    or write.)
+-   NF90\_ENOTINDEFINE Not in define mode. This is returned for netCDF
+    classic or 64-bit offset files, or for netCDF-4 files, when they
+    were been created with NF90\_STRICT\_NC3 flag. (see section
+    [NF90\_CREATE](#NF90_005fCREATE)).
+-   NF90\_ESTRICTNC3 Trying to create a var some place other than the
+    root group in a netCDF file with NF90\_STRICT\_NC3 turned on.

+ `NCID`
+
+:   NetCDF ID, from a previous call to NF90\_OPEN or NF90\_CREATE.
+
+ `VARID`
+
+:   Variable ID.
+
+ `NO_FILL`
+
+:   Set to non-zero value to set no\_fill mode on a variable. When this
+    mode is on, fill values will not be written for the variable. This
+    is helpful in high performance applications. For netCDF-4/HDF5 files
+    (whether classic model or not), this may only be changed after the
+    variable is defined, but before it is committed to disk (i.e. before
+    the first NF90\_ENDDEF after the NF90\_DEF\_VAR.) For classic and
+    64-bit offset file, the no\_fill mode may be turned on and off at
+    any time.
+
+ `FILL_VALUE`
+
+:   A value which will be used as the fill value for the variable. Must
+    be the same type as the variable. This will be written to a
+    \_FillValue attribute, created for this purpose. If NULL, this
+    argument will be ignored.

+
+ `NF90_ELATEDEF`
+
+:   This variable has already been the subject of a NF90\_ENDDEF call.
+    In netCDF-4 files NF90\_ENDDEF will be called automatically for any
+    data read or write. Once enddef has been called, it is impossible to
+    set the fill for a variable.
+
+ `NF90_ENOTINDEFINE`
+
+:   Not in define mode. This is returned for netCDF classic or 64-bit
+    offset files, or for netCDF-4 files, when they were been created
+    with NF90\_STRICT\_NC3 flag. (see section
+    [NF90\_CREATE](#NF90_005fCREATE)).
+
+ `NF90_EPERM`
+

+
+ `varid`
+
+:   Variable ID.
+
+ `name`
+
+:   Returned variable name. The caller must allocate space for the
+    returned name. The maximum possible length, in characters, of a
+    variable name is given by the predefined constant NF90\_MAX\_NAME.
+
+ `xtype`
+
+:   Returned variable type, one of the set of predefined netCDF external
+    data types. The valid netCDF external data types are NF90\_BYTE,
+    NF90\_CHAR, NF90\_SHORT, NF90\_INT, NF90\_FLOAT, AND NF90\_DOUBLE.
+
+ `ndims`
+
+:   Returned number of dimensions the variable was defined as using. For

+    variable is a scalar with no dimensions.
+
+ `dimids`
+
+:   Returned vector of \*ndimsp dimension IDs corresponding to the
+    variable dimensions. The caller must allocate enough space for a
+    vector of at least \*ndimsp integers to be returned. The maximum
+    possible number of dimensions for a variable is given by the
+    predefined constant NF90\_MAX\_VAR\_DIMS.
+
+ `natts`
+
+:   Returned number of variable attributes assigned to this variable.
+
+ `contiguous`
+
+:   On return, set to NF90\_CONTIGUOUS if this variable uses contiguous
+    storage, NF90\_CHUNKED if it uses chunked storage.
+
+ `chunksizes`
+
+:   An array of chunk sizes. The array must have the one element for
+    each dimension in the variable.
+
+ `shuffle`
+
+:   True if the shuffle filter is turned on for this variable.
+
+ `deflate_level`
+
+:   The deflate\_level from 0 to 9. A value of zero indicates no
+    deflation is in use.
+
+ `fletcher32`
+
+:   Set to true if the fletcher32 checksum filter is turned on for
+    this variable.
+
+ `endianness`
+
+:   Will be set to NF90\_ENDIAN\_LITTLE if this variable is stored in
+    little-endian format, NF90\_ENDIAN\_BIG if it is stored in
+    big-endian format, and NF90\_ENDIAN\_NATIVE if the endianness is not
+    set, and the variable is not created yet.
+
+These functions return the value NF90\_NOERR if no errors occurred.
+Otherwise, the returned status indicates an error. Possible causes of
+errors include:
+
+-   The variable ID is invalid for the specified netCDF dataset.
+-   The specified netCDF ID does not refer to an open netCDF dataset.

+6.8 Writing Data Values: NF90\_PUT\_VAR {.section}
+---------------------------------------
+
+The function NF90\_PUT\_VAR puts one or more data values into the
+variable of an open netCDF dataset that is in data mode. Required inputs
+are the netCDF ID, the variable ID, and one or more data values.
+Optional inputs may indicate the starting position of the data values in
+the netCDF variable (argument start), the sampling frequency with which
+data values are written into the netCDF variable (argument stride), and
+a mapping between the dimensions of the data array and the netCDF
+variable (argument map). The values to be written are associated with
+the netCDF variable by assuming that the first dimension of the netCDF
+variable varies fastest in the Fortran 90 interface. Data values are
+converted to the external type of the variable, if necessary.
+
+Take care when using the simplest forms of this interface with record
+variables (variables that use the NF90\_UNLIMITED dimension) when you
+don’t specify how many records are to be written. If you try to write
+all the values of a record variable into a netCDF file that has no
+record data yet (hence has 0 records), nothing will be written.
+Similarly, if you try to write all the values of a record variable from
+an array but there are more records in the file than you assume, more
+in-memory data will be accessed than you expect, which may cause a
+segmentation violation. To avoid such problems, it is better to specify
+start and count arguments for variables that use the NF90\_UNLIMITED
+dimension.

++--------------------------------------+--------------------------------------+
+
+ `ncid`
+
+:   NetCDF ID, from a previous call to NF90\_OPEN or NF90\_CREATE.
+
+ `varid`
+
+:   Variable ID.
+
+ `values`
+
+:   The data value(s) to be written. The data may be of any type, and
+    may be a scalar or an array of any rank. You cannot put CHARACTER
+    data into a numeric variable or numeric data into a text variable.
+    For numeric data, if the type of data differs from the netCDF
+    variable type, type conversion will occur. See [(netcdf)Type
+    Conversion](netcdf.html#Type-Conversion) section ‘Type Conversion’
+    in NetCDF Users Guide.
+
+ `start`
+
+:   A vector of integers specifying the index in the variable where the
+    first (or only) of the data values will be written. The indices are
+    relative to 1, so for example, the first data value of a variable
+    would have index (1, 1, ..., 1). The elements of start correspond,
+    in order, to the variable’s dimensions. Hence, if the variable is a
+    record variable, the last index would correspond to the starting
+    record number for writing the data values.
+
+    By default, start(:) = 1.
+
+ `count`
+
+:   A vector of integers specifying the number of indices selected along
+    each dimension. To write a single value, for example, specify count
+    as (1, 1, ..., 1). The elements of count correspond, in order, to
+    the variable’s dimensions. Hence, if the variable is a record
+    variable, the last element of count corresponds to a count of the
+    number of records to write.
+
+    By default, count(:numDims) = shape(values) and count(numDims + 1:)
+    = 1, where numDims = size(shape(values)).
+
+ `stride`
+
+:   A vector of integers that specifies the sampling interval along each
+    dimension of the netCDF variable. The elements of the stride vector
+    correspond, in order, to the netCDF variable’s dimensions (stride(1)
+    gives the sampling interval along the most rapidly varying dimension
+    of the netCDF variable). Sampling intervals are specified in
+    type-independent units of elements (a value of 1 selects consecutive
+    elements of the netCDF variable along the corresponding dimension, a
+    value of 2 selects every other element, etc.).
+
+    By default, stride(:) = 1.
+
+ `imap`
+
+:   A vector of integers that specifies the mapping between the
+    dimensions of a netCDF variable and the in-memory structure of the
+    internal data array. The elements of the index mapping vector
+    correspond, in order, to the netCDF variable’s dimensions (map(1)
+    gives the distance between elements of the internal array
+    corresponding to the most rapidly varying dimension of the
+    netCDF variable). Distances between elements are specified in units
+    of elements.
+
+    By default, edgeLengths = shape(values), and map = (/ 1,
+    (product(edgeLengths(:i)), i = 1, size(edgeLengths) - 1) /), that
+    is, there is no mapping.
+
+    Use of Fortran 90 intrinsic functions (including reshape, transpose,
+    and spread) may let you avoid using this argument.
+
+Errors {.heading}
+------
+
+NF90\_PUT\_VAR1\_ type returns the value NF90\_NOERR if no errors
+occurred. Otherwise, the returned status indicates an error. Possible
+causes of errors include:
+
+-   The variable ID is invalid for the specified netCDF dataset.
+-   The specified indices were out of range for the rank of the
+    specified variable. For example, a negative index or an index that
+    is larger than the corresponding dimension length will cause
+    an error.
+-   The specified value is out of the range of values representable by
+    the external data type of the variable.
+-   The specified netCDF is in define mode rather than data mode.
+-   The specified netCDF ID does not refer to an open netCDF dataset.
+
+Example {.heading}
+-------
+
+Here is an example using NF90\_PUT\_VAR to set the (4,3,2) element of
+the variable named rh to 0.5 in an existing netCDF dataset named foo.nc.
+For simplicity in this example, we assume that we know that rh is
+dimensioned with lon, lat, and time, so we want to set the value of rh
+that corresponds to the fourth lon value, the third lat value, and the
+second time value:

+Here is an example using NF90\_PUT\_VAR to add or change a section of
+the variable named rh to 0.5 in an existing netCDF dataset named foo.nc.
+For simplicity in this example, we assume that we know that rh is
+dimensioned with lon, lat, and time, that there are ten lon values, five
+lat values, and three time values, and that we want to replace all the
+values at the last time.

+6.9 Reading Data Values: NF90\_GET\_VAR {.section}
+---------------------------------------
+
+The function NF90\_GET\_VAR gets one or more data values from a netCDF
+variable of an open netCDF dataset that is in data mode. Required inputs
+are the netCDF ID, the variable ID, and a specification for the data
+values into which the data will be read. Optional inputs may indicate
+the starting position of the data values in the netCDF variable
+(argument start), the sampling frequency with which data values are read
+from the netCDF variable (argument stride), and a mapping between the
+dimensions of the data array and the netCDF variable (argument map). The
+values to be read are associated with the netCDF variable by assuming
+that the first dimension of the netCDF variable varies fastest in the
+Fortran 90 interface. Data values are converted from the external type
+of the variable, if necessary.
+
+Take care when using the simplest forms of this interface with record
+variables (variables that use the NF90\_UNLIMITED dimension) when you
+don’t specify how many records are to be read. If you try to read all
+the values of a record variable into an array but there are more records
+in the file than you assume, more data will be read than you expect,
+which may cause a segmentation violation. To avoid such problems, it is
+better to specify the optional start and count arguments for variables
+that use the NF90\_UNLIMITED dimension.
+
+In netCDF classic model the maximum integer size is NF90\_INT, the
+4-byte signed integer. Reading variables into an eight-byte integer
+array from a classic model file will read from an NF90\_INT. Reading
+variables into an eight-byte integer in a netCDF-4/HDF5 (without classic
+model flag) will read from an NF90\_INT64

++--------------------------------------+--------------------------------------+
+
+ `ncid`
+
+:   NetCDF ID, from a previous call to NF90\_OPEN or NF90\_CREATE.
+
+ `varid`
+
+:   Variable ID.
+
+ `values`
+
+:   The data value(s) to be read. The data may be of any type, and may
+    be a scalar or an array of any rank. You cannot read CHARACTER data
+    from a numeric variable or numeric data from a text variable. For
+    numeric data, if the type of data differs from the netCDF variable
+    type, type conversion will occur. See [(netcdf)Type
+    Conversion](netcdf.html#Type-Conversion) section ‘Type Conversion’
+    in NetCDF Users Guide.
+
+ `start`
+
+:   A vector of integers specifying the index in the variable from which
+    the first (or only) of the data values will be read. The indices are
+    relative to 1, so for example, the first data value of a variable
+    would have index (1, 1, ..., 1). The elements of start correspond,
+    in order, to the variable’s dimensions. Hence, if the variable is a
+    record variable, the last index would correspond to the starting
+    record number for writing the data values.
+
+    By default, start(:) = 1.
+
+ `count`
+
+:   A vector of integers specifying the number of indices selected along
+    each dimension. To read a single value, for example, specify count
+    as (1, 1, ..., 1). The elements of count correspond, in order, to
+    the variable’s dimensions. Hence, if the variable is a record
+    variable, the last element of count corresponds to a count of the
+    number of records to read.
+
+    By default, count(:numDims) = shape(values) and count(numDims + 1:)
+    = 1, where numDims = size(shape(values)).
+
+ `stride`
+
+:   A vector of integers that specifies the sampling interval along each
+    dimension of the netCDF variable. The elements of the stride vector
+    correspond, in order, to the netCDF variable’s dimensions (stride(1)
+    gives the sampling interval along the most rapidly varying dimension
+    of the netCDF variable). Sampling intervals are specified in
+    type-independent units of elements (a value of 1 selects consecutive
+    elements of the netCDF variable along the corresponding dimension, a
+    value of 2 selects every other element, etc.).
+
+    By default, stride(:) = 1.
+
+ `map`
+
+:   A vector of integers that specifies the mapping between the
+    dimensions of a netCDF variable and the in-memory structure of the
+    internal data array. The elements of the index mapping vector
+    correspond, in order, to the netCDF variable’s dimensions (map(1)
+    gives the distance between elements of the internal array
+    corresponding to the most rapidly varying dimension of the
+    netCDF variable). Distances between elements are specified in units
+    of elements.
+
+    By default, edgeLengths = shape(values), and map = (/ 1,
+    (product(edgeLengths(:i)), i = 1, size(edgeLengths) - 1) /), that
+    is, there is no mapping.
+
+    Use of Fortran 90 intrinsic functions (including reshape, transpose,
+    and spread) may let you avoid using this argument.
+
+Errors {.heading}
+------
+
+NF90\_GET\_VAR returns the value NF90\_NOERR if no errors occurred.
+Otherwise, the returned status indicates an error. Possible causes of
+errors include:
+
+-   The variable ID is invalid for the specified netCDF dataset.
+-   The assumed or specified start, count, and stride generate an index
+    which is out of range. Note that no error checking is possible on
+    the map vector.
+-   One or more of the specified values are out of the range of values
+    representable by the desired type.
+-   The specified netCDF is in define mode rather than data mode.
+-   The specified netCDF ID does not refer to an open netCDF dataset.
+
+(As noted above, another possible source of error is using this
+interface to read all the values of a record variable without specifying
+the number of records. If there are more records in the file than you
+assume, more data will be read than you expect!)
+
+Example {.heading}
+-------
+
+Here is an example using NF90\_GET\_VAR to read the (4,3,2) element of
+the variable named rh from an existing netCDF dataset named foo.nc. For
+simplicity in this example, we assume that we know that rh is
+dimensioned with lon, lat, and time, so we want to read the value of rh
+that corresponds to the fourth lon value, the third lat value, and the
+second time value:

+In this example we use NF90\_GET\_VAR to read all the values of the
+variable named rh from an existing netCDF dataset named foo.nc. We
+assume that we know that rh is dimensioned with lon, lat, and time. In
+this example we query the netCDF file to discover the lengths of the
+dimensions, then allocate a Fortran 90 array the same shape as the
+netCDF variable.

+6.10 Reading and Writing Character String Values {.section}
+------------------------------------------------
+
+Character strings are not a primitive netCDF external data type under
+the classic netCDF data model, in part because FORTRAN does not support
+the abstraction of variable-length character strings (the FORTRAN LEN
+function returns the static length of a character string, not its
+dynamic length). As a result, a character string cannot be written or
+read as a single object in the netCDF interface. Instead, a character
+string must be treated as an array of characters, and array access must
+be used to read and write character strings as variable data in netCDF
+datasets. Furthermore, variable-length strings are not supported by the
+netCDF classic interface except by convention; for example, you may
+treat a zero byte as terminating a character string, but you must
+explicitly specify the length of strings to be read from and written to
+netCDF variables.
+
+Character strings as attribute values are easier to use, since the
+strings are treated as a single unit for access. However, the value of a
+character-string attribute in the classic netCDF interface is still an
+array of characters with an explicit length that must be specified when
+the attribute is defined.
+
+When you define a variable that will have character-string values, use a
+character-position dimension as the most quickly varying dimension for
+the variable (the first dimension for the variable in Fortran 90). The
+length of the character-position dimension will be the maximum string
+length of any value to be stored in the character-string variable. Space
+for maximum-length strings will be allocated in the disk representation
+of character-string variables whether you use the space or not. If two
+or more variables have the same maximum length, the same
+character-position dimension may be used in defining the variable
+shapes.
+
+To write a character-string value into a character-string variable, use
+either entire variable access or array access. The latter requires that
+you specify both a corner and a vector of edge lengths. The
+character-position dimension at the corner should be one for Fortran 90.
+If the length of the string to be written is n, then the vector of edge
+lengths will specify n in the character-position dimension, and one for
+all the other dimensions: (n, 1, 1, ..., 1).
+
+In Fortran 90, fixed-length strings may be written to a netCDF dataset
+without a terminating character, to save space. Variable-length strings
+should follow the C convention of writing strings with a terminating
+zero byte so that the intended length of the string can be determined
+when it is later read by either C or Fortran 90 programs. It is the
+users responsibility to provide such null termination.
+
+If you are writing data in the default prefill mode (see next section),
+you can ensure that simple strings represented as 1-dimensional
+character arrays are null terminated in the netCDF file by writing fewer
+characters than the length declared when the variable was defined. That
+way, the extra unwritten characters will be filled with the default
+character fill value, which is a null byte. The Fortran intrinsic TRIM
+function can be used to trim trailing blanks from the character string
+argument to NF90\_PUT\_VAR to make the argument shorter than the
+declared length. If prefill is not on, the data writer must explicitly
+provide a null terminating byte.
+
+Here is an example illustrating this way of writing strings to character
+array variables:

+6.11 Fill Values {.section}
+----------------
+
+What happens when you try to read a value that was never written in an
+open netCDF dataset? You might expect that this should always be an
+error, and that you should get an error message or an error status
+returned. You do get an error if you try to read data from a netCDF
+dataset that is not open for reading, if the variable ID is invalid for
+the specified netCDF dataset, or if the specified indices are not
+properly within the range defined by the dimension lengths of the
+specified variable. Otherwise, reading a value that was not written
+returns a special fill value used to fill in any undefined values when a
+netCDF variable is first written.
+
+You may ignore fill values and use the entire range of a netCDF external
+data type, but in this case you should make sure you write all data
+values before reading them. If you know you will be writing all the data
+before reading it, you can specify that no prefilling of variables with
+fill values will occur by calling writing. This may provide a
+significant performance gain for netCDF writes.
+
+The variable attribute \_FillValue may be used to specify the fill value
+for a variable. There are default fill values for each type, defined in
+module netcdf: NF90\_FILL\_CHAR, NF90\_FILL\_INT1 (same as
+NF90\_FILL\_BYTE), NF90\_FILL\_INT2 (same as NF90\_FILL\_SHORT),
+NF90\_FILL\_INT, NF90\_FILL\_REAL (same as NF90\_FILL\_FLOAT), and
+NF90\_FILL\_DOUBLE
+
+The netCDF byte and character types have different default fill values.
+The default fill value for characters is the zero byte, a useful value
+for detecting the end of variable-length C character strings. If you
+need a fill value for a byte variable, it is recommended that you
+explicitly define an appropriate \_FillValue attribute, as generic
+utilities such as ncdump will not assume a default fill value for byte
+variables.
+
+Type conversion for fill values is identical to type conversion for
+other values: attempting to convert a value from one type to another
+type that can’t represent the value results in a range error. Such
+errors may occur on writing or reading values from a larger type (such
+as double) to a smaller type (such as float), if the fill value for the
+larger type cannot be represented in the smaller type.

+6.13 Change between Collective and Independent Parallel Access: NF90\_VAR\_PAR\_ACCESS {.section}
+--------------------------------------------------------------------------------------
+
+The function NF90\_VAR\_PAR\_ACCESS changes whether read/write
+operations on a parallel file system are performed collectively or
+independently (the default) on the variable. This function can only be
+called if the file was created (see [NF90\_CREATE](#NF90_005fCREATE)) or
+opened (see [NF90\_OPEN](#NF90_005fOPEN)) for parallel I/O.
+
+This function is only available if the netCDF library was built with
+parallel I/O enabled.
+
+Calling this function affects only the open file - information about
+whether a variable is to be accessed collectively or independently is
+not written to the data file. Every time you open a file on a parallel
+file system, all variables default to independent operations. The change
+of a variable to collective access lasts only as long as that file is
+open.
+
+The variable can be changed from collective to independent, and back, as
+often as desired.
+
+Classic and 64-bit offset files, when opened for parallel access, use
+the parallel-netcdf (a.k.a. pnetcdf) library, which does not allow
+per-variable changes of access mode - the entire file must be access
+independently or collectively. For classic and 64-bit offset files, the
+nf90\_var\_par\_access function changes the access for all variables in
+the file.

+7.1 Attributes Introduction {.section}
+---------------------------
+
+Attributes may be associated with each netCDF variable to specify such
+properties as units, special values, maximum and minimum valid values,
+scaling factors, and offsets. Attributes for a netCDF dataset are
+defined when the dataset is first created, while the netCDF dataset is
+in define mode. Additional attributes may be added later by reentering
+define mode. A netCDF attribute has a netCDF variable to which it is
+assigned, a name, a type, a length, and a sequence of one or more
+values. An attribute is designated by its variable ID and name. When an
+attribute name is not known, it may be designated by its variable ID and
+number in order to determine its name, using the function
+NF90\_INQ\_ATTNAME.
+
+The attributes associated with a variable are typically defined
+immediately after the variable is created, while still in define mode.
+The data type, length, and value of an attribute may be changed even
+when in data mode, as long as the changed attribute requires no more
+space than the attribute as originally defined.
+
+It is also possible to have attributes that are not associated with any
+variable. These are called global attributes and are identified by using
+NF90\_GLOBAL as a variable pseudo-ID. Global attributes are usually
+related to the netCDF dataset as a whole and may be used for purposes
+such as providing a title or processing history for a netCDF dataset.
+
+Attributes are much more useful when they follow established community
+conventions. See [(netcdf)Attribute
+Conventions](netcdf.html#Attribute-Conventions) section ‘Attribute
+Conventions’ in The NetCDF Users Guide.
+
+Operations supported on attributes are:
+
+-   Create an attribute, given its variable ID, name, data type, length,
+    and value.
+-   Get attribute’s data type and length from its variable ID and name.
+-   Get attribute’s value from its variable ID and name.
+-   Copy attribute from one netCDF variable to another.
+-   Get name of attribute from its number.
+-   Rename an attribute.
+-   Delete an attribute.

+
+7.2 Create an Attribute: NF90\_PUT\_ATT {.section}
+---------------------------------------
+
+The function NF90\_PUT\_ATTadds or changes a variable attribute or
+global attribute of an open netCDF dataset. If this attribute is new, or
+if the space required to store the attribute is greater than before, the
+netCDF dataset must be in define mode.
+
+Usage {.heading}
+-----
+
+Although it’s possible to create attributes of all types, text and
+double attributes are adequate for most purposes.
+
++--------------------------------------+--------------------------------------+

++--------------------------------------+--------------------------------------+
+
+ `ncid`
+
+:   NetCDF ID, from a previous call to NF90\_OPEN or NF90\_CREATE.
+
+ `varid`
+
+:   Variable ID of the variable to which the attribute will be assigned
+    or NF90\_GLOBAL for a global attribute.
+
+ `name`
+
+:   Attribute name. Attribute name conventions are assumed by some
+    netCDF generic applications, e.g., ‘units’ as the name for a string
+    attribute that gives the units for a netCDF variable. See
+    [(netcdf)Attribute Conventions](netcdf.html#Attribute-Conventions)
+    section ‘Attribute Conventions’ in The NetCDF Users Guide.
+
+ `values`
+
+:   A numeric rank 1 array of attribute values or a scalar. The external
+    data type of the attribute is set to match the internal
+    representation of the argument, that is if values is a two byte
+    integer array, the attribute will be of type NF90\_INT2. Fortran 90
+    intrinsic functions can be used to convert attributes to the
+    desired type.
+
+Errors {.heading}
+------
+
+NF90\_PUT\_ATT returns the value NF90\_NOERR if no errors occurred.
+Otherwise, the returned status indicates an error. Possible causes of
+errors include:
+
+-   The variable ID is invalid for the specified netCDF dataset.
+-   The specified netCDF type is invalid.
+-   The specified length is negative.
+-   The specified open netCDF dataset is in data mode and the specified
+    attribute would expand.
+-   The specified open netCDF dataset is in data mode and the specified
+    attribute does not already exist.
+-   The specified netCDF ID does not refer to an open netCDF dataset.
+-   The number of attributes for this variable exceeds NF90\_MAX\_ATTRS.
+
+Example {.heading}
+-------
+
+Here is an example using NF90\_PUT\_ATT to add a variable attribute
+named valid\_range for a netCDF variable named rh and a global attribute
+named title to an existing netCDF dataset named foo.nc:

+7.3 Get Information about an Attribute: NF90\_INQUIRE\_ATTRIBUTE and NF90\_INQ\_ATTNAME {.section}
+---------------------------------------------------------------------------------------
+
+The function NF90\_INQUIRE\_ATTRIBUTE returns information about a netCDF
+attribute given the variable ID and attribute name. Information about an
+attribute includes its type, length, name, and number. See
+NF90\_GET\_ATT for getting attribute values.
+
+The function NF90\_INQ\_ATTNAME gets the name of an attribute, given its
+variable ID and number. This function is useful in generic applications
+that need to get the names of all the attributes associated with a
+variable, since attributes are accessed by name rather than number in
+all other attribute functions. The number of an attribute is more
+volatile than the name, since it can change when other attributes of the
+same variable are deleted. This is why an attribute number is not called
+an attribute ID.

++--------------------------------------+--------------------------------------+
+
+ `ncid`
+
+:   NetCDF ID, from a previous call to NF90\_OPEN or NF90\_CREATE.
+
+ `varid`
+
+:   Variable ID of the attribute’s variable, or NF90\_GLOBAL for a
+    global attribute.
+
+ `name`
+
+:   Attribute name. For NF90\_INQ\_ATTNAME, this is a pointer to the
+    location for the returned attribute name.
+
+ `xtype`
+
+:   Returned attribute type, one of the set of predefined netCDF
+    external data types. The valid netCDF external data types are
+    NF90\_BYTE, NF90\_CHAR, NF90\_SHORT, NF90\_INT, NF90\_FLOAT,
+    and NF90\_DOUBLE.
+
+ `len`
+
+:   Returned number of values currently stored in the attribute. For a
+    string-valued attribute, this is the number of characters in
+    the string.
+
+ `attnum`
+
+:   For NF90\_INQ\_ATTNAME, the input attribute number; for
+    NF90\_INQ\_ATTID, the returned attribute number. The attributes for
+    each variable are numbered from 1 (the first attribute) to NATTS,
+    where NATTS is the number of attributes for the variable, as
+    returned from a call to NF90\_INQ\_VARNATTS.
+
+    (If you already know an attribute name, knowing its number is not
+    very useful, because accessing information about an attribute
+    requires its name.)
+
+Errors {.heading}
+------
+
+Each function returns the value NF90\_NOERR if no errors occurred.
+Otherwise, the returned status indicates an error. Possible causes of
+errors include:
+
+-   The variable ID is invalid for the specified netCDF dataset.
+-   The specified attribute does not exist.
+-   The specified netCDF ID does not refer to an open netCDF dataset.
+-   For NF90\_INQ\_ATTNAME, the specified attribute number is negative
+    or more than the number of attributes defined for the
+    specified variable.
+
+Example {.heading}
+-------
+
+Here is an example using NF90\_INQUIRE\_ATTRIBUTE to inquire about the
+lengths of an attribute named valid\_range for a netCDF variable named
+rh and a global attribute named title in an existing netCDF dataset

+ `values`
+
+:   Returned attribute values. All elements of the vector of attribute

+    a scalar. If the attribute is of type character values should be a
+    variable of type character with the len Fortran 90 attribute set to
+    an appropriate value (i.e. character (len = 80) :: values). You
+    cannot read character data from a numeric variable or numeric data

+    Conversion’ in NetCDF Users Guide.
+
+Errors {.heading}
+------
+
+NF90\_GET\_ATT\_ type returns the value NF90\_NOERR if no errors
+occurred. Otherwise, the returned status indicates an error. Possible
+causes of errors include:
+
+-   The variable ID is invalid for the specified netCDF dataset.
+-   The specified attribute does not exist.
+-   The specified netCDF ID does not refer to an open netCDF dataset.
+-   One or more of the attribute values are out of the range of values

+Here is an example using NF90\_GET\_ATT to determine the values of an
+attribute named valid\_range for a netCDF variable named rh and a global
+attribute named title in an existing netCDF dataset named foo.nc. In
+this example, it is assumed that we don’t know how many values will be
+returned, so we first inquire about the length of the attributes to make
+sure we have enough space to store them:

+7.5 Copy Attribute from One NetCDF to Another: NF90\_COPY\_ATT {.section}
+--------------------------------------------------------------
+
+The function NF90\_COPY\_ATT copies an attribute from one open netCDF
+dataset to another. It can also be used to copy an attribute from one
+variable to another within the same netCDF dataset.
+
+If used to copy an attribute of user-defined type, then that
+user-defined type must already be defined in the target file. In the
+case of user-defined attributes, enddef/redef is called for ncid\_in and
+ncid\_out if they are in define mode. (This is the ensure that all
+user-defined types are committed to the file(s) before the copy is
+attempted.)
+
+Usage {.heading}

++--------------------------------------+--------------------------------------+
+
+ `ncid_in`
+
+:   The netCDF ID of an input netCDF dataset from which the attribute
+    will be copied, from a previous call to NF90\_OPEN or NF90\_CREATE.
+
+ `varid_in`
+
+:   ID of the variable in the input netCDF dataset from which the
+    attribute will be copied, or NF90\_GLOBAL for a global attribute.
+
+ `name`
+
+:   Name of the attribute in the input netCDF dataset to be copied.
+
+ `ncid_out`
+
+:   The netCDF ID of the output netCDF dataset to which the attribute
+    will be copied, from a previous call to NF90\_OPEN or NF90\_CREATE.
+    It is permissible for the input and output netCDF IDs to be
+    the same. The output netCDF dataset should be in define mode if the
+    attribute to be copied does not already exist for the target
+    variable, or if it would cause an existing target attribute to grow.
+
+ `varid_out`
+
+:   ID of the variable in the output netCDF dataset to which the
+    attribute will be copied, or NF90\_GLOBAL to copy to a
+    global attribute.
+
+Errors {.heading}
+------
+
+NF90\_COPY\_ATT returns the value NF90\_NOERR if no errors occurred.
+Otherwise, the returned status indicates an error. Possible causes of
+errors include:
+
+-   The input or output variable ID is invalid for the specified
+    netCDF dataset.
+-   The specified attribute does not exist.
+-   The output netCDF is not in define mode and the attribute is new for
+    the output dataset is larger than the existing attribute.
+-   The input or output netCDF ID does not refer to an open
+    netCDF dataset.
+
+Example {.heading}
+-------
+
+Here is an example using NF90\_COPY\_ATT to copy the variable attribute
+units from the variable rh in an existing netCDF dataset named foo.nc to
+the variable avgrh in another existing netCDF dataset named bar.nc,
+assuming that the variable avgrh already exists, but does not yet have a
+units attribute:
