  1. We run the "geogrib.exe":
cd WPS-4.4
./geogrib.exe
  1. We link the meteorological global information downloaded from ds083.3:
./link_grib.csh ~/data/met/NCEP_GDAS/tmp_2018_07/gdas1.fnl0p25.20180*

This procedure will create GRIBFILE.<> files.

  1. We run the script to "ungrib" the meteorological files.
./ungrib.exe
  1. We're going to create the 'met_em' files:
./metgrid.exe
