Hi James,

I think that you could still use CDO but before the interpolation step, just extract the variable from the input file. So, you could use following commands (for example, tas variable),

1 - ncks -v xlon,xlat,mask,tas source.nc source_tas.nc
2 - cdo remapbil,destgrd.txt source_tas.nc destination_tas.nc

in this case you might want to check the content of the 'destgrd.txt' file. It must contain correct grid information (only one grid definition). Otherwise CDO could give type generic error.

I hope it helps,

Regards,

Hi RegCNET,

I have a netcdf file with RegCM output data that I have prepared with the help of CDO. However the data is in ROTMER and I need to convert it to NORMER. I have tried with cdo remapbil but I get an error saying that its type generic.

Can anyone suggest a way to regrid data? Because I cannot find out how to do it with cdo

Regards,

James
