About Research Forecasting MetOcean Studies News Current Marine Data

The GROW Fine Arctic (GFA) Hindcast is Oceanweather's comprehensive metocean study of the Arctic Sea.  The wind and wave hindcasts were all made with basin-wide grids of spacing 0.25 degrees latitude (28 km) by 0.75 degrees longitude. All hindcast time series are available in either OWI's OSMOSIS format (for current licensees of OSMOSIS) or ASCII.  The standard continuous hindcast covers 29 years (1983-2011) of data.  Spectra is also archived and available at select locations.

Purchasers interested in the entire Arctic region should consider joining the PAMOS JIP.
