Dr. ABdelghani Chehbouni is a doctor in hydrology and remote sensing, he received his B.S. in fluids Mechanics from University Paul Sabatier, Toulouse, France in 1987 and his M.S. in Environment Science from the National Polytechnic Institute of Toulouse in 1989, and a PhD in Hydrology and Remote Sensing from University Paul Sabatier in Toulouse in 1992. He has been working at the University of Arizona for 18 months and the Jet Propulsion Laboratory for 2 years. He is co-investigator of several Remote Sensing programs (VEGETATION, ERS2/ATSR2, EOS). His main research interests include the application of remotely sensed data in land-surface-atmosphere models especially in arid semi-arid regions. He participates in several international experiments (MONSOON'90, Hapex Sahel) and he wasa co-leader of the Semi-Arid-Land-Surface-Atmosphere (SALSA) international program. He joined CESBIO in 2000 as the leader of hydrology group.
