<div>Dear NCL experts,</div>
<div> </div>
<div>If I have a shapefile data of a certain province as well as a netcdf file
containing global grid data, how can I get the data exactly in the province from
the nc file (I want to have the province-averaged values of climate variables)?
please help me,Thanks very much!</div>
