Steve,

I have been tinkering around with the script you gave me
a while back. I have attached it below. It seems to run
fine with no errors however, I notice when I display the
new calculated grdnam (stbc) in gdprof it outputs a
level of 975mb for den. Using garp and looking at
the pres@0%none (station pressure), I can see that the
station pressure for den is less than 900mb. I would think
that the first level displayed in the output file from gdprof
would less than the station pressure. I am thinking about
this correctly? I have attached my gdprof.csh and its output
as well.

Thank you again,
Matt

Steve,

You mentioned in a prior email if I explained to you how
I wanted to calculate mixing depth, you may be able to
give me some assistance with scripting. An idea I have
been considering is comparing two forecast hours.
I am using strictly the eta model. My thoughts were
if I could somehow take the 2m hagl tmpk say at the
f06 and raise it adiabatically and as that tmpk is being
raised, I would like to compare those temp values to the
tmpk values from f00 at various altitudes above ground.
If the lifted adiabatic air from f06 intersects or becomes
cooler than the tmpk from the f00, I could say that
intersection (altitude) is a tentative mixing height.
Would you know of way do this calculation for a chosen
grid area? Let me know when you have a chance.

Thank you,
Matt Fearon
