How to calculate GEopotential Height at all pressure levels
Added by mubashar dogar over 1 year ago
DEar CDO Users,
I would like to compute Geopotential height along pressure levels. I have the following GFDL-CM2.1 model netcdf output file. In this model netcdf output file, the Geopotential height at model pressure levels is not available. Kindly advise how can I calculate geopotential height using combination of other available model variables which are given in following "ncdump -h" information. Tank you
Regards,
Mubashar
