Hello,
I am new to this list and an NCL novice. I plan to install NCL on a
Linux machine running RedHat Enterprise v3.0. I would like to run NCL in
batch mode to compute horizontal divergence of wind using uv2dv_cfd,
which supposedly computes the divergence using centered finite
differences. The program uv2dv_cfd supposedly requires that the input
data be written to a latitude-longitude grid. The source files for which
I want to calculate divergence contain numerical model data from the NAM
(formerly the Eta), and eventually the WRF, which I can acquire/generate
in either netCDF or GRIB format.
Question 1-- Assuming that I cannot use uv2dv_cfd on the native grids,
what software do I use to write the (netCDF and/or GRIB formatted) data
to a latitude-longitude grid, that can then be utilized by uv2dv_cfd?
The software needs to be run from the command line (no GUI's please.)
Question 2-- I also would like to compute horizontal gradients of a
scalar. The data are written to HDF-EOS files, and I can also convert to
netCDF. The data will include missing values, and is of limited area
(not Global.) Anyone aware of how I could use NCL to compute the
gradients (in batch mode)? Otherwise, what other software can I use?
Again, only command-line software.
Any assistance will be greatly appreciated.
