Probably not what your problem is, but thought I would raise it since it happened to me:

Some variables, like ice pellets occurrence is 1 for yes, and undefined for no, so if there are no ice pellets, you get an entire grid undefined. In those cases you need to specify to change undefined to say -9999 then when you shade grid boxes, it counts as ( < 1).

Hi Everyone,

I'm working on the WAFS implementation. The system requires .grib2 files. I get work, but I have some trouble with the CAT files.
I generated a .ctl file with Gribtoctl program and  ran gribmap. But when I executed the GrADS, its showed a "entire grid undefined" dialog box. I do anything, but still the same dialog box.

Is .ctl file creating problems? Or the .grib2 files? Where can I download .ctl files?

Thanks for yout attention,

Regards,
