After talking with Jean Bidlot we concluded that what we are asking our contributors for in GRIB2 language is :
parameter ( WMO GRIB 2 ) | Discipline | Category | parameter | Grid | vertical level | Description | ||
---|---|---|---|---|---|---|---|---|
1 | U-component of wind ( 10 m ) | 0 [ M products ] | 2 [ Momentum ] | 2 | . regular lat-long grid . grid spacing free for the contributor to chose . not need to be global . bitmap ? | Code table4.5 – Fixed surface types and units ?? 102 Specific altitude above mean sea level 103 Specified height level above ground
| ||
2 | V-component of wind ( 10 m ) | 0 [ M products ] | 2 [ Momentum ] | 3 | ||||
3 | Significant height of combined | 10 [ O products ] | 0 [ Waves ] | 3 | ?? typeOfFirstFixedSurface = 1 [Ground or water surface]
101 Mean sea level
| |||
4 | Peak wave period | 10 [ O products ] | 0 [ Waves ] | 34 | Mean wave period based on the second moment of the frequency spectrum | |||
5 | Mean zero-crossing wave period | 10 [ O products ] | 0 [ Waves ] | 28 | ||||
6 | Direction of combined wind | 10 [ O products ] | 0 [ Waves ] | 14 | Mean wave direction |
