The DUACS system produces high quality multimission altimetry Sea Level products for oceanographic applications, climate forecasting centers, geophysic and biology communities... These products consist in directly usable and easy to manipulate Level 3 (along-track cross-calibrated SLA) and Level 4 products (multiple sensors merged as maps or time series) and are available in global and regional version (Mediterranean Sea, Arctic, European Shelves …).

Since mid 2015, the operational production of the along track and Sea Level maps is now generated as part as the Copernicus Marine Environment and Monitoring Service (CMEMS). The system today merges data from 6 satellites (Jason-3, Sentinel-3, Jason-2, Altika, Cryosat-2 and HY2A). This paper presents the main achievements of the SLTAC during the 3 years of CMEMS, as well as the perspectives.
