Gembud,
I have model data that was converted to a GEMPAK file in sigma
coordinates. I want to convert the data to pressure coordinates, and I
want values below ground level. Is this possible? Here's my gdvint
settings. I'm running on version 5.9.3.
gdfile=18z.gem
gdoutf=18z.gem
gdattim=021225/0000F018
gvcord=sgma:100/pres
glevel=$level
maxgrd=1000
garea=grid
vcoord=pres;none/L
I thought the "/L" was the trick according to the gdvint help, but I
still have missing values below ground level. I do know that it works
with thta, but maybe not pressure?
Thanks for any insight,
Dave
