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 Surface MSS_CNES_CLS11 Mean sea surface height wrt T/ P reference ellisoid computed on a 7 years period (1993-1999). 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 Topography MDT_CNES-CLS09 Mean sea surface height above geoid computed on a 7 years period (1993-1999). The Mean Dynamic Topography results from the ocean mean geostrophic currents
Mean Dynamic Topography RioMed Mean sea surface height above geoid computed on a 7 years period (1993-1999). This sea surface height is specifically computed over Mediterranean Sea.
Global tide FES2012 Ocean tide elevations and currents computed by up-to-date finite elements modelling and data (both tide gauges and altimeter) assimilation.
Global tide FES2004 Ocean tide computed by finite elements modelling and data (both tide gauges and altimeter) assimilation.
Global tide FES99 Ocean tide computed by finite elements modelling and data (both tide gauges and altimeter) assimilation.
Atmospheric Corrections Dynamic Atmospheric Correction Correction of the ocean response to atmospheric wind and pressure forcing, computed using Mog2D baroropic model for high frequencies (i.e. less than 20 days), and an Inverted Barometer correction for lower frequencies.
