[ncl-talk] geopotential height calculation

[Zhifeng Yang]

Hi Adam and Barry,

Sorry for less information. The vertical grid in MPAS is sigma. The
horizontal grid is Voronoi mesh, unstructured grid. I saw there is a
section in NCL processing MPAS model data. I thought MPAS is very common
while using NCL. Here I attached the output from ncdump and
printVarSummary. There are three types of model output files. diagnos,
history, and restart. I am planning to use history output to calculate the
geopotential height.

I took a look of several wrf related functions in NCL, e.g.
wrf_interp_3d_z, wrf_interp_2d_xy. However, they are for latitude-longitude
grids, like WRF.
