Jacques Stum received a "Thèse de troisième cycle" in Atmospheric Physics in 1985, from the Université Blaise Pascal (Clermont-Ferrand, France). In 1985, he joined the Groupement pour le Développement de la Télédétection Aérospatiale (GDTA), as a software engineer, to specify the production software of the ERS-1 microwave radiometer (level 1.5) and altimeter (level 2). In 1990, he joined the CLS Space Oceanography Division where he is in charge of altimeter and microwave radiometer software specification for different altimetric missions (TOPEX/POSEIDON, ERS-2, ENVISAT, JASON-1). He also works on in-flight product verification and data validation, with a special interest for microwave radiometer measurements.

Pierre Thibaut received in 1994 a Ph.D. in Electronic and Signal Processing from the " Institut National Polytechnique de Toulouse ", France. The field of research was the synthetic aperture radiometer and the interferometric signal processing. His thesis has been done in collaboration with the " Centre National d'Etudes Spatiales "  in Toulouse and Matra Marconi Space Toulouse. In 1996, he joined the CLS Space Oceanography Division and is now in charge of the analysis of the instrumental features of the POSEIDON altimeter. He is also involved in the definition of the ground processing of the JASON altimeter data (instrumental processing, calibration algorithm ....).

Role of CLS in the SMOS mission:

CLS role in the SMOS project would be, first, to help refine the science requirements for SSS data and, in particular:

CLS could then contribute to the specification of geophysical data processing algorithms over ocean, based on the results of the previous studies and knowledge of interferometric radiometry.
