Global Hybrid Mean Sea Surface 2023

Sea Surface Height

The mean sea surface (MSS) is an important field in physical oceanography, geophysics, and geodesy. In principle, it corresponds to the time-averaged height of the ocean surface.

This Global Hybrid Mean Sea Surface 2023 combining is a hybridization of Scripps_CLS22, CNES_CLS22, and DTU21 MSS above WGS84 reference ellipsoid. This surface is available on a regular grid (1/60°x1/60°, 1 minute):
