The SMOS project at LOCEAN/IPSL

The SMOS (Soil Moisture and Ocean Salinity) / ESA (European Space Agency) satellite mission  (PI: Y. Kerr, CESBIO) has been successfully launched on November 2nd, 2009. It is the first satellite mission measuring Sea Surface Salinity (SSS) and Soil Moisture from space using an L-band interferometric radiometer (see more on SMOS blog).

Since 1999, LOCEAN/IPSL is strongly involved in the SSS measurement using L-band radiometry. LOCEAN/IPSL studies contribute to the CATDS (Centre Aval de Traitement des Données SMOS) expertise center.

LOCEAN/IPSL is one of the expert laboratories working on algorithms implemented for the SSS retrieval in the ESA operational chain. These ESL studies are coordinated by ARGANS company and are performed in tight collaboration with LOS/IFREMER and ICM laboratories and ARGANS, ACRI-ST and CLS companies.

LOCEAN/IPSL participes to two SMOS/ESA Cal/Val projects, strongly supported by CNES, in order to optimize modelling of L-band radiometric signal and retrieved salinity and to one ESA Support to Science Element project:
