PARAMETERS

Below is a list of all agreed upon parameters. Participating Centers are expected to produce output fields in GRIB2 data format and with consistent units. All units are defined by the WMO in the GRIB2 manual . For more information please refer to Guide to the WMO Table Driven Code Form.

Rules for parameter exchanges and GRIB2 encoding can be found here.
