Below is a list of all agreed upon parameters. Participating Centres 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.

Model level parameters
Output of analyses on (hybrid) model levels are stored up to a height of about 15km every six hours (at 00/06/12/18UTC).
