> *"Problem: NCEP has updated its real-time GFS GRIB2 files, beginning
> 2012-05-22_12:00:00. This is causing ungrib to extract incorrect data (at
> 80 m above surface) for surface fields. If your domain includes a pole or
> the Prime Meridian (0° longitude), program real may abort. If your domain
> lies elsewhere, the real program may not abort, but you will likely get
> incorrect surface fields (e.g. stronger surface winds).
> Solution: A file (rd_grib2.F) <http://www.mmm.ucar.edu/wrf/src/fix_wps/rd_grib2.F>needs
> to be replaced in the /WPS/ungrib/src directory. This new file contains a
> solution to the problem. Replace the old file with the new and recompile
> WPS (no need to reconfigure)."*
