[ncl-talk] Fwd: Masking a U.S. county from a netcdf file

[Mohammadhassan Mohegh]

Hi

I'm working with WRF model output and I need to average the differences of
2 outputs within a county. Is there any way to do this? Are there
shapefiles or netcdf files available for US counties that NCL recognizes?

I have created a netcdf file containing these counties using ARCGIS. The
problem is that it does not have the same grid and I can't use the mask()
function with it. Does any one know of a

Thanks in advance for your help.
