-The netCDF Operators NCO version 4.6.2 are ready. 
+The netCDF Operators NCO version 4.6.3 are ready. 
 
 http://nco.sf.net (Homepage, Mailing lists)
 http://github.com/nco (Source Code, Releases, Developers)
 
 What's new?
 
-4.6.2 is mainly a stability release to polish existing features and to
-add minor new ones. The exception is the new JSON backend. 
-NCO now prints CDL, "Traditional NCO", XML, and JSON. Babel-icious eh?
+4.6.3 adds many new convenience features to existing functionality
+like JSON, ncap2, ncremap, and ncclimo. Multi-dimensional bracketing
+completes our JSON implementation. ncap2 adds a convenient UDUnits
+conversion function. ncremap and ncclimo support long options.
+ncclimo supports binary climatology generation and annual-mean mode. 
 
-We built the JSON backend to help a project (DOE Terraref). 
-Our first choice was to adopt an off-the-shelf netCDF->JSON tool.
-However, no existing solution worked for us.
-JSON is a loose syntax, and we made necessary design choices that
-suited our application, and left some choices for later.
-Are there syntactical variants you want us to add?
-
-Some users of netCDF version 4.4.1 cannot build NCO from scratch
-because a bug in the nc-config command kills NCO's 'configure;make'.
-Unidata will ship a corrected nc-config in netCDF 4.4.2.
-The 4.4.2-development branch already contains the necessary fix.
-
-Work on NCO 4.6.3 has commenced. Planned improvements include more
-flexibility in handling extensive variables during regridding, CMake
-support, and brackets for multi-dimensional array values in JSON.
+Work on NCO 4.6.4 has commenced. Planned improvements include CMake
+builds, more flexibility in handling extensive variables during
+regridding.
 
 Enjoy,
 Charlie
 
 NEW FEATURES (full details always in ChangeLog):
 
-A. JSON backend
-   Similar the CDL and XML backends, ncks now supports JSON.
-   To obtain JSON, use --jsn or --json instead of --cdl/--xml.
-   ncks --json -v one ~/nco/data/in.nc
-   {
-     "variables": {
-       "one": {
-         "type": "float",
-         "attributes": {
-           "long_name": "one"
-         },
-         "data": 1.0
-       }
-     }

-   Other related options (-v, -g, -m, -M) have their usual meanings.

+A. ncclimo supports "binary climos" and annual-mean mode.
+   Binary climos are climos created from merging two climos, rather
+   than re-computing a climos from raw input. 
+   This saves disk space and time for long climos.
+   Annual-mean mode allows ncclimo to process input files that are
+   annual rather than monthly means.
+   http://nco.sf.net/nco.html#ncclimo
+
+B. ncrcat and ncra now re-base data (move to a common time origin)
+   from arbitrary time units in multiple calendar systems.
+   Previously, re-basing only worked when the basetime (i.e., the 
+   YYMMDD in units like "XXX since YYMMDD") changed.
+   Now rebasing takes into account the full units, both the increment
+   (XXX) and the basetime (YYMMDD). Thanks to Dave Allured for the
+   suggestion and Henry Butowsky for the re-implementation.
+   http://nco.sf.net/nco.html#rbs
+
+C. ncap2 now supports converting data between any two compatible units
+   systems supported by UDUnits. The udunits() function takes and
+   input variable and a UDUnits dimension string.
+   T[lon]={0.0,100.0,150.0,200.0};
+   T at units="Celsius";
+   T=udunits(T,"kelvin"); 
+   print(T);  
+   273.15, 373.15, 423.15, 473.15 ;
+   The method auto-magically reads var_in at units and var_in at calendar 
+   (so, YES, this works with dates) attributes as necessary.
+   Thanks to Henry Butowsky for this feature.
+   http://nco.sf.net/nco.html#udunits_fnc
+
+D. ncclimo and ncremap now support long options, e.g., 
+   ncclimo --case=caseid --input=drc_in --output=drc_out --map=rgr_map
+   ncremap --input_file=in_fl --destination=dst_fl --output_file=out_fl
+   http://nco.sf.net/nco.html#ncclimo
+   http://nco.sf.net/nco.html#ncremap
+
+E. ncclimo and ncremap now save the full command line with which they
+   were invoked as a single global attribute. 
+   Previously portions were saved as separate attributes.
+   The new attributes are climo_command and remap_command.
+   Their contents will exactly replicate (except for datestamps)
+   the climatologies or regridded files they were created for.
+   This improved provenance comes at the cost of up to a few kB more
+   metadata in each file.
+
+F. ncks can now print attribute CDL types as comments.
+   CDL attribute types can be hard for humans to discern, so now
+   ncks will print the type when invoked with -D 1 or greater.
+   The printed file is fully CDL-compliant and works with ncgen.
+   Credit to whomever first thought of this feature, and implemented
+   it in some CDL output someone sent me.
+   zender at firn:~/nco$ ncks -D 1 -C --cdl ~/nco/data/in_4.nc
+   ...
+   att_var:byte_att = 0b, 1b, 2b, 127b, -128b, -127b, -2b, -1b ; // byte
+   att_var:char_att = "Sentence one.\n",
+      "Sentence two.\n" ; // char

+   att_var:int_att = 73 ; // int
+   att_var:float_att = 73.f, 72.f, 71.f, 70.01f, 69.001f, 68.01f, 67.01f ; // float
+   att_var:double_att = 73., 72., 71., 70.01, 69.001, 68.01, 67.010001 ; // double
+   att_var:ubyte_att = 0ub, 1ub, 2ub, 127ub, 128ub, 254ub, 255ub, 0ub ; // ubyte
+   att_var:ushort_att = 37us ; // ushort
+   att_var:uint_att = 73ul ; // uint
+
+G. JSON brackets
+   Similar the CDL and XML backends, ncks supports JSON (as of 4.6.2).
+   ncks now prints strided brackets to demarcate inner dimensions
+   of multi-dimensional variable data.  
+   Invoking with --json vs. --jsn_fmt=4 on foo(2,3,4) yields:
+   "data": [[[0.0, 1.0, 2.0, 3.0], [4.0, 5.0, 6.0, 7.0], [8.0, 9.0,
+   10.0, 11.0]], [[12.0, 13.0, 14.0, 15.0], [16.0, 17.0, 18.0, 19.0],
+   [20.0, 21.0, 22.0, 23.0]]] 
+   "data": [0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0,
+   11.0, 12.0, 13.0, 14.0, 15.0, 16.0, 17.0, 18.0, 19.0, 20.0, 21.0,
+   22.0, 23.0] 
+   Bracketed data are suitable for pasting into Python. 
+   More sample output at:
+   http://dust.ess.uci.edu/tmp/in.json and other *.json files.
+   Thanks to Henry Butowsky for implementing the bracketing.

-A. Multi-arguments refer to the format of command-line key-value pairs
-   that NCO uses to support four different features that can have too
-   many parameters to set via traditional command line arguments.
-   The four features are regridding (rgr), global-attribute-adding
-   (gaa), precision-preserving compression (ppc), and ENVI image
-   processing for the DOE Terraref project (trr). Formerly, users were
-   required to supply one value per command line option for these
-   features, e.g., 
-   "--rgr lat_nbr=64 --rgr lon_nbr=128 --rgr lat_grd=cap ..."
-   The new multi-argument feature allows users to aggregate multiple
-   key-value pairs per command line argument, e.g., 
-   "--rgr lat_nbr=64#lon_nbr=128#lat_grd=cap# ..."
-   Now all key-value pairs related to a single feature (like
-   regridding, compression) can be provided as one arument!
-
-   The string that delimits each pair is user-configurable and
-   defaults to a single hash "#". Change it with, e.g., --dlm=":".
-   Ensure your delimiters are not special shell characters, and are
-   escaped (with backslashes) if present in key or value strings. 
-   Thanks to Jerome Mao for implementing multi-arguments.

-A. All builds tested on LLVM 8.0.0 and GCC 6.2.1 toolchains.
-
 BUG FIXES:
 
-A. ncclimo and ncremap could fail if ${BASH_SOURCE[0]} is unavailable.
-   This could occur, e.g., with the dash shell and/or due to software
-   modules that modify users' environments. 
-   This portability issue has been resolved.
-
-B. ncatted failed to implement NaN on some MinGW systems with, e.g.,
-   ncatted -O -a _FillValue,fll_val,m,f,nan ~/nco/data/in.nc ~/foo.nc
-   We think this has been fixed. The workaround is to upgrade or use
-   ncatted on *NIX or MacOS. Thanks to James Adams for reporting this.
-
-C. ncks CDL now prints correct tokens for uint, int64, uint64 types.
-   These are "ul", "ll", "ull", respectively. Previously NCO used
-   different tokens because ncgen <= 4.3.0 choked on "ll" formats.
-   So this was an intentional NCO "feature", not a bug.
-   Use ncgen >= 4.3.1 to parse these CDL files.
+A. None!

 Peak consumption occurs when storing simultaneously in memory

 one input weight, one conformed/working weight, one weight tally, 
 one input mask, one conformed/working mask, and
 one output variable. 
+ at acronym{NCO}'s tally arrays are of type C-type @code{long}, whose size

+three-eighths and two-eighths of these requirements apiece.
 If weights and masks are @emph{not} specified 
 (i.e., no @samp{-w} or @samp{-a} options)
 then @command{ncwa} requirements drop to @math{MS <= 3VT}
 (one input variable, one tally array, and the output variable). 
+The output variable is the same size as the input variable when
+averaging over a degenerate dimension.
+However, normally the output variable is much smaller than the input, 
+and is often a simple scalar, in which case the memory requirements
+drop by @math{1VT} since the output array requires essentially no
+memory. 
+
+All of this is subject to the type promotion rules mentioned above.
+For example, @command{ncwa} averaging a variable of type
+ at code{NC_FLOAT} requires @math{MS <= 16VT} (rather than @math{MS <= 8VT}) 
+since all arrays are (at least temporarily) composed of eight-byte
+elements.
+Without mask or weights, the requirements for @code{NC_FLOAT} are
+ at math{MS <= 6VT} (rather than @math{MS <= 3VT} as for @code{NC_DOUBLE}) 
+due to temporary internal promotion of both the input variable and the
+output variable to type @code{NC_DOUBLE}. 
+The @samp{--flt} option that suppresses promotion reduces this to

+The @code{udunits()} function looks for the attribute of

+A quirk of this function that due to attribute propagation
+ at code{varOut@@units} will be overwritten by @code{varIn@@units}. 
+It is best to re-initialize this attribute AFTER the call. 
+In addition if @code{varIn@@units} is of the form 
+ at code{"time_interval since basetime"} then the calendar attribute
+ at code{varIn@@calendar} will read it.
+If it does not exist then the calendar used defaults to mixed
+Gregorian/Julian as defined by UDUnits. 
+ 
+If @code{varIn} is not a floating point type then it is promoted to
+ at code{NC_DOUBLE} for the system call in the Udunits library;  
+and then demoted back to to its original type after.

+ at unnumberedsubsec Extended Climatologies
+ at command{ncclimo} supports two methods for generating extended
+climatologies: Binary and Incremental.
+Both methods lengthen a climatology without requiring access to 
+all the raw monthly data spanning the time period.
+The binary method combines, with appropriate weighting, two previously
+computed climatologies into a single climatology. 
+No raw monthly data are employed.
+The incremental method computes a climatology from raw monthly data
+and (with appropriate weighting) combines that with a previously
+computed climatology that ends the month prior to raw data.
+The incremental method was introduced in @acronym{NCO} version 4.6.1
+(released August, 2016), and the binary method was introduced in
+ at acronym{NCO} version 4.6.3 (released December, 2016).
+
+ at c fxm edit to distinguish extended from binary
+Both methods, binary and incremental, compute the so-called ``extended
+climo'' as a weighted mean of two shorter climatologies,
+called the ``previous'' and ``current'' climos.
+The incremental method uses the original monthly input to compute the
+curent climo, which must immediately follow in time the previous climo 
+which has been pre-computed.
+The binary method use pre-computed climos for both the previous and
+current climos, and these climos need not be sequential nor
+chronological. 
+Both previous and current climos for both binary and incremental methods
+may be of any length (in years); their weights will be automatically
+adjusted in computing the extended climo.
+
+The use of pre-computed climos permits ongoing simulations (or lengthy
+observations) to be analyzed in shorter segments combined piecemeal,
+instead of requiring all raw, native-grid data to be simultaneously
+accessible.
+Without extended climatology capability, generating a one-hundred
 year climatology requires that one-hundred years of monthly data be
 available on disk. 
 Disk-space requirements for large datasets may make this untenable.

    scale_factor: If present for a variable, the data are to be multiplied by this factor after the data are read by the application that accesses the data
    add_offset: If present for a variable, this number is added to the data after the data are read by the application. If both scale_factor and add_offset attributes are present, the data are first scaled before the offset is added. 
    When scale_factor and add_offset are used for packing, the associated variable (containing the packed data) is typically of type byte or short, whereas the unpacked values are intended to be of type float or double. Attribute's scale_factor and add_offset should both be of type intended for the unpacked data, e.g., float or double.
