Last I checked gempak did not have this functionality.
I I was thinking it would be nice to have a
theta es wrt ice. (so we could calculate dry PV,
moist PV, ice PV - was this your thought as well?)
There is little research on PV wrt to ice, maybe
it doesn't make a difference, maybe it does, I don't
know - yet.

All gempek releases in recent memory support
sub-hourly grids. I think. I've never used this
capability, but am pretty sure it exists. Sorry, can't
give you a how to, which is probably what you wanted.
