[gradsusr] how to convert curvilinear grid format to regular grid format

[Kishore Ragi]

Dear Anubhav,

Hope the following two CDO commands will work for you.


cdo -f nc -sellonlatbox,X1,X2,Y1,Y2 -random,raxb template.nc  ( here your
desired template is created)
cdo -remapcon,template.nc your_file.nc disired_file.nc  (Hope you see your
desired gridded nc file is created)

Where X1, X2 are longitudes, Y1,Y2 are latitudes, a is number of points in
the longitude you selected, b is is number of points in the latitude you
selected.

Cheers,

Kishore
