I bought climate data from IMD. Now I cannot open the .grd files. I want to use it in GIS. HELP! Aside from grads software, what else can I use to open the file? I tried every possible way so please help me in this.
If you can use Python, there is a package 'IMDLIB' to download and handle gridded data from IMD. See the section on 'Reading IMD datasets' https://pratiman-91.github.io/2020/10/05/IMDLIB.html. A while back I had written a R script (if I recall using packages raster and rgdal) to read the .grd files. But rgdal is obsolete now and the python package would be better suited.
Since you mentioned Grads and are able to use it, you can convert the .grd to .ctl, which can then be converted to NetCDF (.nc/.nc4) formats if you more comfortable with those formats. But this will required some knowledge of command line tools like NCO/CDO. See here -> https://stackoverflow.com/questions/32390349/converting-grads-grd-to-netcdf-nc
Good luck!
