Hi HansPeter,
I also wanted to do this, but I'm not sure if it's possible....at least
for my grids. I have grids of U, V, and Z on a global lat/lon grid. I
was going to compute the ageo wind by differencing the U,V grids with a
computed geostrophic wind. To get the geostrophic wind from the height
field is a computation with derivatives. But, based on what I found in
the IDV help:
"Any derived quantity that involves a derivative...and is produced from
a grid with a lat/lon domain will give incorrect results...."
I won't be able to compute the geostrophic wind.. [I'm using version 2.0].

Hi all
I would like to draw flow fields of the ageostrophic component of
numerical (u,v) wind fields. Anybody out there who has already
implemented this in some way. I would be very grateful in receiving
some information.
