Since 1997, the multisatellite DUACS system (Data Unification and Altimeter Combination System) has been providing high quality multi-mission altimetry Sea Level products for oceanographic applications, climate forecasting centers, geophysics and biology communities worldwide. They consist in directly usable and easy to manipulate Level 3 (along-track cross-calibrated Sea Level Anomaly SLA) and Level 4 (multiple sensors merged gridded gap-free) products, for global and regional applications. Initiated as part of the CNES/SALP project, this production is now carried out jointly with the Copernicus Marine and Climate Change Services. 

This presentation provides an overview of the DUACS products and the planned developments for the coming years.
