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.
