[gradsusr] Regarding Skew-T plot from .ctl file

[Jeff Duda]

I'm not really sure at this point. The error message is definitely clueing
you into the fact that there is some kind of grid mismatch between your
dimension environment, your data file, and what is going on within the
plotting script. I noticed your control file lacks a PDEF entry. Not sure
if that matters.

You'll need to show us the exact commands (with outputs) you're running
from the moment you initialize GrADS to the moment you call the script and
get those errors. All the information needed to debug is yours to uncover.
We can't offer you more help without more outputs.
