Note that wgrib2 must be installed for ReadGrib to work for current grib files, and wgrib may need to be installed when looking at archived data. wgrib2 is much more powerful, but it reads only GRIB-2 data, not GRIB-1. Using the wgrib2 -lon function to select location and the grep command to narrow down to the fields I want works, in that it does return the values I require. Basically, there are 2 steps: use wgrib to extract selected variables from grib2 data, and save into NetCDF file. Grids include analysis and forecast time steps at a 3 hourly interval from 0 to 240, and a 12 hourly interval from 240 to 384. It is used mainly for encoding outputs from meteorological models.
