- 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:
| Name | units | |
|---|---|---|
Atmospheric forcing: | 10 metre U wind component | m/s |
10 metre V wind component | m/s | |
| Wave Fields: | Significant height of combined wind waves and swell | m |
Peak wave period | s | |
| Mean zero-crossing wave period | s | |
Mean wave direction | degree true |
