3km Artic wave model (WAM) from the ARC-MFC Copernicus project
Two pan-Arctic operational wave products are available at MET Norway throughout the European project ARC-MFC Copernicus. One is a forecast and the other is a hindcast. Both use the wave spectral model WAM version Cycle 4.7 in the same domain as shown in the figure with a horizontal resolution of 3 km.
The forecast product is produced 2 times a day (at 00 and 12) with a 5 day and 10 day prediction into the future time length respectively. The model uses as forcing fields: surface winds (from ECMWF), surface ocean currents, sea ice concentration and sea ice thickness (from the forecast TOPAZ system).
The model is forced with winds merged between winds from ERA5 reanalysis and winds from a downscaled 2.5 km Harmony-Arome hindcast (NORA3). The ice variables used come from Topaz reanalysis. The wave hindcast files are on thredds at this address: https://thredds.met.no/thredds/catalog/windsurfer/mywavewam3km_files/catalog.html
