[gradsusr] Lats4d!

[Heiner Körnich]

Hi Abbas,

I can't help you with Lats4d, but I can recommend the climate data operators
CDO for such netcdf-operations:
https://code.zmaw.de/projects/cdo

Alternatively, you could use NCO, the netcdf operators:
http://nco.sourceforge.net/nco.html

Regrads,
Heiner
