[netCDF #RKE-155992]: separate

You can probably find a way to do this by scripting existing netCDF
utility programs from one of these freely available software packages:

   NCO (netCDF Operators)
   http://nco.sourceforge.net/

   NCL (NCAR Command Language)
   http://www.ncl.ucar.edu/

   CDO (Climate Data Operators)
   https://code.zmaw.de/projects/cdo

If you know Python, another software package with sophisticated
built-in time handling for climate data is:

   netcdf4-python
   http://code.google.com/p/netcdf4-python/

It's also possible to do what you want with netCDF library calls in a
C or Fortran program, but I think using one of the packages above
would be simpler.  These packages support more sophisticated analysis
capabilities than the netCDF I/O libraries or the basic netCDF 
utilities (ncdump, nccopy, ncgen), so learning about one of them would 
be useful in future analyses of netCDF data ...

Also these software packages have helpful online forums or mailing 
lists.  Some other user may have already done something similar to what 
you want to do.  For example:

    NCO Help Forum:
    https://sourceforge.net/p/nco/discussion/9830

    NCL mailing lists:
    http://www.ncl.ucar.edu/Support/email_lists.shtml

Good luck in finding a simple way to split your yearly file into monthly 
files ...
