How can I remap my data to 0.5x0.5 degree Crodex SA (South Asia) grid from 0.44x0.44 degree (WAS-44)

Added by ANKUR VISHWAKARMA over 4 years ago

I want to know the input given in .grd file (including, xsize and ysize) to remap my Crodex SA (South Asia) data to 0.5x0.5 degree grid from 0.44x0.44 degree (WAS-44 data, see attached file). Also, suggest the method to apply to remap them.

Hi Ankur,

you can remap the data directly to 0.5x0.5 lonlat grid with

cdo remapbil,r720x360 file_0.44x0.44.nc file_0.5x0.5.nc

Extract the CORDEX SA region

cdo -sellonlatbox,-32.12,84.92,-21.56,57.2 file_0.5x0.5.nc file_0.5x0.5_SA.nc

Or in one step

cdo -sellonlatbox,-32.12,84.92,-21.56,57.2 -remapbil,r720x360 file_0.44x0.44.nc file_0.5x0.5_SA.nc
