Model details

• Providers are asked to add their model details to the page Model details by providers. (these pages have been retired now)
• The summary of all model details can be seen in Models' description page.

General requirements

• Domain and resolution
  • 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.
• Parameters
  • following set of parameters was agreed:

    • 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]

• Forecast-observation matching
  

  • The matching between forecast and observation will be based on a nearest grid point approach.

  • No match-up will be performed if any of the surrounding grid points are missing in order to minimise land contamination effects.

• Data format
  
  • The data shall be encoded in GRIB format  (edition 2) using WMO compliant  templates. ECMWF can assist in the conversion into GRIB edition 2.
  • Encoding details
    

    • Refer to the page LC-WFV technical details for complete specification of the required input data.

• Data exchange
  • Refer to the page LC-WFV technical details for expected test and future production work flow.
