Product details
Operational analysis and forecast system [01/02/2017->D+13] that delivers daily averaged status of physical and sea ice parameters descriptive of the global ocean - Temperature, Salinity, Sea Surface Height, Currents and Sea Ice Thickness, Fraction and Drift - weekly updated analyses and forecasts over the period [D-1 to D+13]. The numerical files are distributed on a native 1/4° grid (~28km at the equator).
