Abstract:

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 …).

With the integration of HY-2A data in 2014, the Near Real Time system now merges data from 4 satellites. In parallel of the constellation management, on April 2014, the entire catalogue was significantly upgraded with impacts on scientific content and format, improving the quality and accessibility of the products. Besides, a full reprocessing of the whole altimetry time series has been performed allowing us to make available a set of 21 years of homogeneous along–track and map products.

In 2015, we are now starting a new step. 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), a European project launched in May. Besides, new satellites, Jason-3 and Sentinel-3, will be launched in the coming month, 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 the latest development and the main perspectives for the DUACS Sea level products in the coming years.
