Re: Skew-T plotting issue

Hi David,

Don Morton of ARSC/University of Alaska-Fairbanks wrote to me offline with something that might help:

Don't know if this is at all useful. I don't even remember how I did it all. But, it sounds sort of like what he wants. Here's a link to what it looks like:

I've included the NCL code that Don sent me.
