- The fields have to be provided on a regular latitude‐longitude grid at the resolution that is best matching the native resolution of the direct model output.
- The data shall be encoded in GRIB format (edition 2) using WMO compliant templates. ECMWF can assist in the conversion into GRIB edition 2.
- The data will be pulled via ftp from an agreed server location at the data producer's site.
- Participants are committed to guarantee a steady and reliable provision of their data and to communicate any relevant changes.
- The following set of parameters is required:
| Parameter Name | units | GRIB2 | |
|---|---|---|---|
Atmospheric forcing: | 10m U wind speed 10-meter neutral wind speed over wave = 40 | m/s | |
| 10m V wind speed | m/s | discipline = 0 parameterCategory = 2 parameterNumber = 3 | |
| Wave Fields: | Significant height of wind waves
( Significant height of combined wind waves and swell = 3 ) | m | |
Peak period Peak wave peridod | s | discipline = 10 parameterCategory = 0 parameterNumber = 34 | |
| Mean wave period based on the second moment of the frequency spectrum | s | ||
Mean wave direction | degree true |
