I intend to use SST data for my WRF runs, but data are in binary format and I need to convert them to GRIB2 format. I appreciate if somebody with same experience help me solve the issue.
If you're using python, you can open the binary file using the regular file open (with the option rb for reading binary). Once you do that, you can use one of a few libraries that allow you to write GRIB files, like pupygrib or pygrib. Since binary files are not self-describing, you'll have to get information on the coordinates of the dataset as well to include in the GRIB output.
