Hello Kunal, I also was unable to initially open this file using the 'ncdump' utility, but after looking at it in a hex editor I see that it is a netcdf/hdf4 file. You will need to install a verison of the netcdf library that supports hdf4 data access and configure GRaDS to work with it. I hope this is useful, have a pleasant day, -Ward > Hello > > Hello i am using GrADS software for visualization the netcdf file.
