NCL is updated continually to include new tables. In addition, users may input their own parameter tables, if desired.
You can also use NCL to learn more about a grib file: grib_read.txt

ECMWF Reanalysis Data-Assimilation (ERA40)
NCL supports accessing datasets in a variety of formats including
GRIB1 and GRIB2. (GRIB2 support was added in version 4.3.0.) NCL is aware
of the various Grid
Parameter Tables (GBT) needed to properly assign meta data( attributes and coordinate variables) to
the decoded variable arrays.
era40_1.ncl:
A simple color plot from an grib file.
gsn_csm_contour_map_ce is the plot interface that creates a cylindrical equidistant plot.
era40_2.ncl:
A simple vector plot.
gsn_csm_vector_map_ce is the plot interface that draws vectors over a map.
