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_CLS15
Mean 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 Topography

MDT_CNES-CLS13
Mean 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 Topography

SMDT2014-20Y_MED
Mean sea surface height above geoid computed on a 20 years period (1993-2012).
This sea surface height is specifically computed over Mediterranean Sea.
 

Global tide

FES2014
Ocean 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.

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.
