Notes:

1.  Data are numeric without units, although they might be given quantitative meaning through a code table defined by the data provider.  The emphasis is on a displayable "picture" of some phenomenon, perhaps with certain enhanced features.  Generally, each datum is an unsigned, one octet integer.  The size of the datum is indicated in Section 5 of the GRIB2 message.

2.  Data are in specified physical units.
