About us

The CERSAT (Centre ERS d'Archivage et de Traitement) / Laboratory of Oceanography From Space is part of IFREMER (French Research Institute for Exploitation of the Sea). It was created in 1991 as a node of the ESA (European Space Agency) ground segment for the ERS-1 and ERS-2 Earth observation satellites, performing off-line processing of the ERS-1 and ERS-2 "low-bit rate" sensors. The CERSAT has then evolved towards a multi-mission data centre for archiving, processing and validating data from spaceborne sensors (such as altimeters, scatterometers, radiometers, SAR,...) with a focus on sea surface parameters and air-sa interactions.

Activities
The CERSAT blends IFREMER Laboratoire D'Oc√©anographie Spatiale (LOS) together with a data management team to bring forward innovative research and development focusing on the state of the ocean, and particularly air-sea interactions, its survey, its evolution and its impact on the global climatic system. This ambition is built upon the analysis and combination of ocean observation coming primarly from Earth Observation satellites but also experimental campaigns, in situ measurements and modeling, …
Facility
The CERSAT is part of IFREMER (French Research Institute for Exploitation of the Sea) and is located in its main center in Brest, France. A dedicated building hosts both our research and operational activities.
