Netcdf data files of Global Mean Temperature and Outgoing Longwave Radiation are available and the shapefile (polygon) of a state (province) of India is in hand then what is the procedure we must follow in Matlab to extract the Netcdf data file only of the region which lies within the polygon?
Ricardo Nogueira Servino
One way is to get your 'lon' and 'lat' variables from your netCDF file and filter only points that are inside the polygon defined by the shapefile. You can use the 'inpolygon' function for that:

Then, just get whatever variable you need from your netCDF file with the filtered indexes for X and Y.
