SkewT-LogP script using station data

[Dan Swank]

Hello,

I am looking for a .gs script that can plot a traditional SkewT/LogP
diagrams using GrADS DTYPE station data.

I am well aware of the Bob Hart plotskew.gs script
which does this, but this script appears to only know how to use gridded
data with vertical levels - is this incorrect?  And if so, does anyone
know of an existing script that can work with station data?

Thanks in advance.
