Yann H. Kerr received the engineering degree from the "Ecole Nationale Supérieure de l'Aéronautique et de l'Espace" (Toulouse, France) in radar and telecommunications, and the M.Sc. degree from Glasgow University (Glasgow, Scotland) in electronics and electrical engineering and a Ph.D from the Université Paul Sabatier (Toulouse, France). From 1980 to 1985 he was employed by the Centre National d'Etudes Spatiales (Toulouse, France). In 1985 he joined the Laboratoire d'Etudes et de Recherches en Télédétection Spatiale as a Research Scientist, where from May 1987 to December 1988 he was on leave of absence to work at the Jet Propulsion Laboratory, California Institute of Technology, Pasadena. His fields of interest are in the theory and techniques for microwave and thermal infrared remote sensing of the Earth, with emphasis on hydrology and vegetation monitoring. He has been working at CESBIO since 1995

Research in the field of the use of satellite data (short wave, but mainly thermal infrared and microwaves) for assessing the water cycle in arid and semi arid environment and fluxes at the surface atmosphere interface.

Member of the Hapex Sahel Coordination team, and steering committee. Coordinator of the French Remote sensing programme for Hapex Sahel, Scientific manager of the Hapex Sahel Data base. Scientific experiment PI during Hapex Sahel on scaling effects and soil moisture retrieval. Research on the synergisms between the different wavelengths. Science leader since the beginning on the MIRAS project for ESA (Interferometric 2D system), Leader of the RAMSES proposal accepted by CNES for Phase A studies. Principal investigator in the EOS program as well as in the ESA ERS1 and 2 programs.Member of the IRIS and the HYDROSTAR Science team.

Role in the SMOS mission:

Lead investigator, Yann Kerr will devote most of his efforts to the project management so as to reach a successful completion of the mission. He will consequently, be responsible for the overall mission including mission design, implementation, data processing and dissemination. He will act as the interface between ESA, the ESAC, national entities, industry an science groups. On the science part he will be in charge of the land group and be assisted by the Co LI who will be in charge of the Ocean Group, as well as the group and sub group co-ordinators. He will also be assisted by the Project manager for day to day operations of the project.
