Global Mean Sea Surface

The mean sea surface is the displacement of the sea surface relative to a mathematical model of the earth and it closely follows the geoid. Amplitudes ranges between +/- 100 meters.

DTU10 Ocean wide Mean Sea Surface height (relative to the Ellipsoid) has been mapped with a resolution of 1 minute by 1 minute corresponding to 2 minute by 2 minute resolution at Equator.
