The Sentinel-3A satellite, which carries among other instruments a dual-frequency SAR altimeter (SRAL) was launched on 2016, February 16th (the launch of Sentinel-3B is foreseen for 2017). The Payload Data Ground Segment (PDGS) provides among others marine Level 2 products (along-track mono-mission product containing information to compute sea level anomaly (orbit, altimeter range, geophysical corrections and models, etc.)).

In the frame of the Copernicus Programme funded by the European Union, CNES with its subcontractor CLS are in charge to develop and operate the Sentinel-3 Marine Altimetry L2P-L3 Service. The value added sea level anomaly L2P products are along-track mono-mission products, providing as much as possible the same corrections and models for several altimeter missions, in order to facilitate inter-mission comparisons. The L3 products contain the sea level anomaly after inter-calibration with a reference mission.

CNES and CLS are for more than 20 years involved in operational exploitation of altimetry missions. This new L2P-L3 Service for Sentinel-3 is based on the existing operational system in place for Jason-2, CryoSat-2, SARAL, etc. It takes benefits of the well-proven organization and experience on past and existing activities. This service and its products will be presented in detail.
