Aviso global sea surface height products
Aviso has been distributing Topex/Poseidon and ERS altimetric data worldwide since 1992. Since launches of new altimetric mission, series of products has been completing the Aviso catalogue. Following table presents applications, features and time availability of all available products obtained by satellite or combining available data of all satellites.
The Copernicus Marine and Environment Monitoring Service (CMEMS) is in charge of the processing and distribution of Ssalto/Duacs gridded "allsat" series and along-track Sea Level Anomalies, Absolute Dynamic Topographies and Geostrophic velocities over the Global Ocean, Mediterranean Sea, Black Sea, European Seas and Acrtic Ocean areas, in Delayed-Time and in Near-Real-Time .
The Copernicus Climate Change Service (C3S) is in charge of the processing and distribution of Ssalto/Duacs gridded Delayed-time "twosat" series of Sea Level Anomalies, Absolute Dynamic Topographies and Geostrophic velocities over the Global Ocean, Mediterranean Sea, Black Sea.
All those products were formerly distributed by Aviso+ with no changes in the scientific content.
Note that the Mozambique area and the Climatologies are still disseminated by Aviso+.
