Cursus: Ecole Normale Superieure de Jeunes Filles(1962-1965); Agregee de Physique(1965); Docteur es-Sciences Physiques(1972). Present job: full time scientist in CNRS (Directeur de Recherches).
From 1965 to 1987: research on Space Plasma Physics: propagation and generation of waves in the magnetosphere. Responsible for relaxation sounders onboard: GEOS1(ESA,1977); GEOS2(ESA,1978); ISEE1(ESA/NASA,1977) including provision of hardware, data handling and scientific use of data.
From 1988 onward: study of the ocean/atmosphere exchange of CO2 at large scale using both satellite(wind speed, SST, ocean color) and in-situ(PCO2 and related parameters, including launching CARIOCA buoys) data. Long term global scale monitoring of air-sea CO2 exchange coefficient. Multi-year estimation of air-sea CO2 flux at regional scale. Validation of satellite wind speed measurements. PI for the use of scatterometer data(ERS1 and 2/AMI; ADEOS/NSCAT; QUIKSCAT), co-I for the use of ocean color data(Seawifs,ADEOS/OCTS).Etcheto, J., and L.

Role in the SMOS mission:
Participate in the definition of the instrument and data reduction specifications for oceanographic needs with special emphasis on multiyear, large scale studies. Participate in studies of the physics of the measurements including oceanographic campaigns with special emphasis on the influence of wind speed on the signal. Derive methods to take this effect into account in the SSS retrieval. Participate in the validation of the retrieved SSS. Use SSS in synergy with other satellite measurements (SST, ocean color) and in-situ measurements (PCO2 and related parameters) to estimate the CO2 concentration in the ocean surface layer and to deduce the air-sea CO2 flux at regional scale using satellite wind speed measurements.
