Product details
Daily-mean, hourly-mean and 6hourly-instantaneous forecast data [01/01/2007->D-1 to D+9] of the Global Ocean physics and sea ice parameters with a daily update providing : Temperature, Salinity, Sea Surface Height, Currents and Sea Ice thickness, fraction and velocities- , Numerical files are displayed on a 1/12° native grid (~9.3km at the equator).
