The MIOST (Multiscale Interpolation Ocean Science Topography) experimental altimeter product provides grids at delayed-time, at global scale, 1/10° spatial resolution, the sea surface height (MSLA and MADT) as well as the geostrophic currents, resulting from specific processing. Use for regional studies, ocean variability (mesoscale circulation,...).

The Mean Dynamic Topography (MDT) is the temporal mean of the Sea Surface Height above the Geoid over a reference period (here 1993-2012). The Hybrid Mean Dynamic Topography contains the MDT-CNES-CLS18 for the global coverage and the MDT CMEMS 2020 for the Black Sea (MDT-CMEMS2020-BLK) and the Mediterranean Sea (MDT-CMEMS2020-MED).

The Mean Dynamic Topography MDT-CNES-CLS22 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.
