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. It uses 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). There is an improvement on the coverage and representation of large structures in Arctic.


Please visit the product page and the description.


Note that a HYBRID MDT CNES-CLS22-CMEMS2020 is also available: it contains the global MDT CNES-CLS22 and the CMEMS2020 MDTs on the Mediterranean and Black Seas.
