North Atlantic - Arctic Ocean model
HYCOM-CICE
Dansk version
The 3D ocean model HYCOM and the sea-ice model CICE is developed at the University of Miami and Los Alamos National Laboratory. The models are fully coupled at each time step. Output are the surface variables sea level and ice conditions (concentration, thickness, velocity, convergense, strength, etc.) and 3-dimensional maps of current, temperature and salinity at sigma levels.

Model set-up
The DMI HYCOM-CICE set-up covers the Atlantic, north of about 20°S and the Arctic Ocean, with a horizontal resolution of about 10 km. Model forcing is ECMWF weather forecasts. A 144 hour forecast is produces twice daily, at 00 and 12 UTC.
