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.
