André Chanzy received the B.S. and Ph.D. degrees in physics of the environment from the "Institut National Agronomique Paris-Grignon" Paris, France in 1985 and 1991, respectively.
Since 1986, he has been with the INRA/Soil Science group at Avignon, France. His main field of research is the application of microwave remote sensing (active and passive) associated to thermal infra-red and in situ observation to infer hydrological fluxes. From 1991 to 1995 he was principal investigator in four experiments based on the use of microwave radiometry (PORTOS 91-93-95 in the Avignon remote sensing test site and Hapex Sahel 1992). His research focussed on the soil moisture estimation on bare soil and soil covered by sparse vegetation, the roughness influence on the microwave emission and the estimation of the effective temperature. He has also an expertise in soil heat and water fluxes modeling as well as in soil moisture and surface fluxes field measurements

André Chanzy will be involved in the SMOS project on the following aspects :
- Definition of land applications, especially those concerning the agricultural sciences and the estimation of evaporation in case of soils or soil sparsely covered by vegetation.
- development of algorithms for soil moisture estimation (he belongs to the physics of measurements SMOS group).
- Experimental studies with the SMOS demonstrator used over land in pre-launch experiments.
- Definition and contribution to the validation experiments, which will be done after SMOS launch.
