[Staging #FZM-387181]: Code for CCL in NSHARP?

I do not believe NSHARP has that capability, though I am not totally sure.  To 
be honest though, we no longer support/maintain the GEMPAK software package; it 
has transitioned to a community supported model on Github 
(https://github.com/Unidata/gempak/).  There is also an email list we manage, 
the "gembud" list.  Instructions on how to join that are on the Github page as 
well.  I'd recommend you pose your GEMPAK questions there, though again for 
this issue I don't believe NSHARP can calculate CCL.  I could be wrong.

I took a look at the SHARPpy code base because I thought it did compute CCL, 
but after reviewing that code it doesn't look like that capability exists.  To 
be honest I'm a little surprised by that.  Likewise that community is probably 
better equipped to address this as SHARPpy isn't one of our packages; maybe 
it's a capability that could be added.

One last thing I want to point you towards is MetPy, our Python package for 
meteorological applications.  MetPy can indeed calculate CCL: 
https://unidata.github.io/MetPy/latest/api/generated/metpy.calc.ccl.html.  If 
you haven't used MetPy before there can be a small learning curve; if you have 
any questions either respond to me and I'll answer what I can or I'll forward 
it to our Python group.  OR, you can always write them directly at 
address@hidden.

Please let us know if you have any further questions.

Best,
-Mike
