The Mean Dynamic Topography MDT-CNES-CLS2022 is an estimate of the mean over the 1993-2012 period of the sea surface height above geoid. Use of the latest GOCO06S geoid model (based on the complete GOCE mission fully reprocessed and 14 years of GRACE data) and 30 years of altimetry and in-situ data (hydrologic, drifters and High Frequency radar on a limited area).
