Ask Question but I tried just to convert to the netCDF using wgrib2 infile -netcdf outfile and checked the result by plotting wind vectors with Python and the results looked good to Can you share the command and also the output from grib2json? As I said, if I. A new CONVERGE HDF5 loader reads CONVERGE 3. Running the WRF-EMS takes 3 steps: ems_prep (fetching data to initialize, such as the NAM or GFS, and processing it into a format the WRF can understand), ems_run (the actual physics) and ems_post (converting the netCDF output to a more friendly output, such as grib2, GEMPAK, BUFR, etc. Reading WRF model data¶. The WRF, located near the SSTs, will accumulate and condition retrieved waste before transfer to a DST. ncl: This example shows how to plot WRF-ARW data using gsn_csm_contour_map, but using the native map projection provided on the WRF output file.
