 Hi,I think you should use shapefile mask in NCL. Following link is related to the subject.https://www.ncl.ucar.edu/Applications/shapefiles.shtml

 Hello together,

I'm relatively new to NCL and have a general question about selecting 
coordinates.

Currently I read out the temperature for a large region from GFS data or 
rahter from GRIB files.

This is easy and works perfectly. In the next step I wanted to read out 
the temperature only for a certain country and display it as an xy-plot.

And this is exactly where I got a problem. How can I specify the 
coordinates in NCL in a way that my coordinate specification only 
considers a certain country.

It would be very nice if I could see this in a code example.

Is it possible to cut the GRIB file to the corresponding coordinates 
before?

Thanks a lot.
