Dear All
I would be very much grateful if anyone can make a masking file in netcdf file using the region_n.msk: 448 rows x 304 columns [binary file]. The details are given in below link. Further, this Netcdf file can be used to mask any netcdf file based on our required regions.

Region Masks

Region masks for the Northern (n). The files contain a 300-byte header, followed by a two-dimensional byte array stored by rows in column order. Regions are assigned different pixel values as shown in the following table.
