If you were to read your netCDF files with NCDF_File object from the
Coyote Library, you will be able to get this information directly from
the GetVarData method that reads the data out of the file. The FILLVALUE
keyword returns the missing data value, and the MISSINGINDICES keyword
returns the indices of the missing values in your data set. Note that
the method also applies whatever offset and scale factor are present in
the file to the data when it is read from the file.
