Combined mean dynamic topography - MDT CNES-CLS18

Types of dataset: auxiliary products
Contents:  The Mean Dynamic Topography MDT-CNES-CLS18 is an estimate of the mean over the 1993-2012 period of the sea surface height above geoid. This is consistent with the reference time period also used in the SSALTO DUACS products.
Use: ocean circulation, operational oceanography
Description: use of the latest GOCO05S geoid model (based on the complete GOCE mission, 10.5 years of GRACE data) and 25 years of altimetry and in-situ data (hydrologic and drifters). (More information)
Geographic coverage: global, 1/8°
Distribution media: Authenticated FTP, gridded data extraction tool and OpdenDap
Condition of access: The MDT-CNES-CLS18 is a standard product as stated in the licence agreement. Please see our FAQ to access this product (distinction if you are already an Aviso+ user or not).
