Hi all,
I want to view model output in lambert projection stored as netcdf
files using GRADS 1.9b2.
http://grads.iges.org/grads/gadoc/SDFdescriptorfile.html says this can
be done and gives a WRF example. Looking at this I assume that this is a
matter of putting the right keywords and values in "global" attributes.
I have tried this. The file opens fine, but does not do the
transformation. Below is the relevant part of the ncdump for the file.
Can anyone help me?
Thanks.
Bryan
