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

You can check your own control file to verify this (because I can't see it
here), but I suspect the problem is a mismatch between the expected field
names in the script and what your data file actually has present. You will
have to change the values of 'u', 'v', 'tc', and 'td' most likely, to
whatever the actual field names are in your data set. And if you don't have
3D dewpoint specifically, you'll have to calculate it manually before
running the script.
