GRIB (from GRIdded Binary, or General Regularly-distributed Information in Binary form) has two editions - GRIB2 is the second version. It is common in weather history and forecast.

GRIB2 is specified by the WMO in FM92-GRIB2. The format is self-describing, although there is an opaque "local use" section. GRIB2 is now more common than GRIB1 for new data. An alternative (more common outside the United States of America) is NetCDF.
