TOPAZ4
Area: Arctic Ocean
Period: 1991-2014
Data available: YES
Institution: Norwegian Meteorological Institute (NO), Copernicus Marine Environment Monitoring Service (CMEMS)
Model: HYCOM model
Resolution: The model's native grid covers the Arctic and North Atlantic Oceans, is obtained by comformal mapping and has fairly homogeneous horizontal spacing (between 11 and 16 km). 28 hybrid layers are used in the vertical (z-isopycnal); 12.5 km at the North Pole (equivalent to 1/8 deg)
Data assimilated: remotely sensed sea level anomalies, sea surface temperature, sea ice concentration, Lagrangian sea ice velocities (winter only, since 2002), as well as temperature and salinity profiles from Argo floats
Assimilation method: Determinstic version (100-members) of the Ensemble Kalman filter (DEnKF; Sakov and Oke 2008)
Forcing and relaxation used: ERA interim
