remapbil (Abort): Unsupported grid type: generic

Hello,

I am using the command
" cdo setgridtype,lonlat -select,name=so -remapbil,ll1deg_grid.nc -setgridarea,areacello.nc aux.nc out_1-deg.nc "
and getting the error messages:

" Warning (cdfScanVarAttributes) : NetCDF: Variable not found - areacello
   cdo(3) remapbil (Abort): Unsupported grid type: generic                  "

Data in aux.nc uses a rotated grid and CDO seems not being able to use remapbil when processing such a grid.

Do you have any suggestions or perhaps an undocumented function that could help me remapping this file?

Thanks a lot in advance.

Regards,
Eduardo

Hi Eduardo,

You have to select the variable so before the remapping:

 cdo -remapbil,ll1deg_grid.nc -select,name=so -setgridarea,areacello.nc aux.nc out_1-deg.nc

Otherwise CDO tries to remap also all other variables, and this is not possible for the variables sigma_bnds and zlev_bnds. See the result of sinfon.
