Aviso regional sea surface height products

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.
Indeed CMEMS and C3S are dedicated to the distribution of operatio
nal products and AViso+ now focuses on the distribution of inoovative products.
Note that the Mozambique area and the Climatologies are still disseminated by Aviso+.

Product type 

Ssalto/Duacs Experimental along-track and gridded products (sea surface height and velocities)

Contents: several experimental products: 1/ 5Hz along-track 2/ gridded computed with Dynamic Interpolation, 3/ gridded combining altimetry and drifters. The proposed variables are sea surface heights and velocities computed with respect to a seven-year mean. Delivered in delayed time for periods defined in the Handbook.
Use: ocean variability (mesoscale circulation, ...)
