CDO

Hi Uwe, do you know how to handle this kind of output from cclm model? The postprocessing software I am use can't handle this grid.

The coordinates of this curvilinear grid are the same for each row and column. That means you can convert these coordinates simple to a regular lonlat grid:

cdo setgridtype,lonlat lffd1999010100tmax.nc  result.nc

I am back on the same topic to see if the attached file can also be converted to lonlat? When I do it as on Uwe previous suggestion I am getting an error message:
cdo setgridtype (Abort): Unsupported grid name: lonlat
HDF5-DIAG: Error detected in HDF5 (1.8.13) thread 0:
#000: H5T.c line 1766 in H5Tclose(): not a datatype
major: Invalid arguments to routine
minor: Inappropriate type

Error (cdf_close) : NetCDF: HDF error

I attach the file expecting support.

Thanks
