Hello,
I have a 3D temperature dataset (cartesian grid, with equidistant points
in each direction), which results from a convection model; the vertical
temperature profile is controlled, among other factors, by a constant
vertical adiabatic gradient, which I would like to get rid of. So what I
would like to do is to get a "reduced temperature T'" by
T'(x,y,z)=T(x,y,z)-z*(dT/dz),
with (dT/dz)=const. and z=0 at the top of the model. I guess that this
should be possible with the Compute module, but the problem is: How do I
get the current z position of the grid point I want to reduce? I'm not
very experienced with DX yet and didn't find concrete information on
which kind of data field I would have to feed into the second input tab
of the Compute module, so any hints are welcome.
PS: Of course, I could reduce the temperature before loading the data
into DX, but that would mean that I'd have to generate another large
data file, which I would like to avoid.
