Session: Application development for Operations

Presentation type: Type Oral

The DUACS system has produced, up to now, as part of the CNES/SALP and the MyOcean projects, 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 4 satellites (Jason-2, Altika, Cryosat-2 HY2A). This year, new satellites, Jason-3 and Sentinel-3, were launched and will contribute to the robustness of this service. Moreover, the processing of the sea level can be improved to fully exploit this increase of real time altimetry observations, combined with the advanced technology of the new sensors. This paper will present how this new constellation will impact the multimission products quality in 2016 and in the coming years.
