+Note on argument types
+----------------------
+
+Many of these functions accept Python datetime objects,
+numpy datetime64 objects, or anything that can be turned
+into a numpy array of datetime64 objects. These objects are inherently
+64-bit so if other arguments (ex. longitude and latitude arrays) are
+32-bit floats internal operations will be automatically promoted to
+64-bit floating point numbers. Where possible these are then converted
+back to 32-bit before being returned. In general scalar inputs will also
+produce scalar outputs.
