Yeah, that time axis information makes no sense at all. The unit “month as %Y%m.%f” doesn’t conform to any standard I know of. The coordinate values for the time dimension don’t make much sense either. You will need to use ‘xdfopen’ with a descritpor file that has a complete TDEF entry, but I’m not sure what the initial time should be:
TDEF time 330 linear ??? 1mo

Yes. Try running it on your file:

and post the output here. If it is very long, you can edit out stuff about the data variables.

Do you know what could be the error?

Hi, Noele,
GrADS doesn’t suppor udunits2. You need to download ftp://cola.gmu.edu/grads/data2.tar.gz
and put the contents of that tar file in a directory that is either /usr/local/lib/grads/ or some other directory of your choosing. If you put it someplace of your choosing, then set the environment variable GADDIR to point to that location.
