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 or WGS84 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-CLS18 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.
Internal Tide MIOST MIOS-IT MIOST-IT solution is based on an original gridding process using ocean signals modes variability and all altimeter measurements available on the nearly entire altimeter era.
Coastal tide X-TRACK Tidal Constants Coastal tidal constants computed for 73 constituents by using harmonic analysis for long-time series missions.
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. Wet tropospheric correction GPD+ dataset where the correction is computed by combining all available observations in the vicinity of the point: valid measurements from the on-board microwave radiometer, from Global Navigation Satellite System (GNSS) coastal and island stations, and from scanning imaging MWR on board various remote sensing missions.

Customizable homepage

The new home page is composed of blocks called "widgets".

Rearrange the blocks with a "Click & Drop".

Hide a widget with the cross at the top right. Reset or add a widget with the "wrench" icon. The "User" and "Public" profiles offer a predefined organization.

All the modifications are automatically saved as cookies on your machine so as to enable you to have your own specific AVISO+.

Browsing menu and breadcrum trail

To ease your browsing through AVISO+, you can use at any time the main banner items with the interactive submenus or use the browsing menu on the left side of the screen (it is open by default). For more readiness of the page contents, you can fold and unfold the browsing menu by clicking on the tab. At any time you can know where you are thanks to the browsing menu or the breadcrum at the top of the page.
