Auxiliary products
Auxiliary products are most often satellite altimetry by-products, but sometimes they are combined with other types of data (in situ, tide gauges..).
Mean Sea SurfaceMSS_CNES_CLS15Mean sea surface height wrt T/ P reference ellisoid computed on a 20 years period (1993-2013). This Mean Sea Surface (also called MSS) corresponds to marine geoid undulations (±120 meters ) and to the "permanent" sea level rise (1-2 meters). |  |
Mean Dynamic TopographyMDT_CNES-CLS18Mean sea surface height above geoid computed on a 20 years period (1993-2012). The Mean Dynamic Topography results from the ocean mean geostrophic currents |  |
Mean Dynamic TopographySMDT2014-20Y_MEDMean sea surface height above geoid computed on a 20 years period (1993-2012). This sea surface height is specifically computed over Mediterranean Sea. |  |
Global tideFES2014Ocean tide elevations (amplitude, phase), tide loading and tide currents computed by up-to-date finite elements modelling and data (both tide gauges and altimeter) assimilation. |
