  1. Laurent Kergoat CESBIO (CNRS/CNES/IRD) Toulouse France People from CESBIO involved in AMMA (African Monsoon Multi-Disciplinary Analyses) : Eric Mougin, Patricia de Rosnay, Valerie Le Dantec Josiane Seghieri, François Lavenu, Franck Timouk, Bernard Mougenot, Pierre Hiernaux. Remote sensing (active, passive mwave, optic), biogeochemistry, ecophysiology, surface-atmosphere interactions) AMMA : UE + french + UK + German projects. Gourma Niamey Ouémé Dynamics of African monsoon : LOP : 2000-2010, EOP : 2005-2007, including SOP 2006

  2. Gourma mesoscale Site (~300 x 100 km) Bamba local Site(17.1°N, 1.3°W) 50 mm 100 mm Hombori Supersite(15.4°N, 1.6°W) Raingauge AMMA Raingauge Mali Met station+rad. Bal. LE Flux station H flux station Long term vegetation surve sitey Agoufou local Site(15.3°N, 1.5°W) 350 mm 450 mm

  3. Agoufou : radiative balance 2002, 2003, 2004 - ... seasonal and interannual effects : grasses, litter + surface soil moisture effects Bamba : 2004- … higher albedo, no or very weak vegetation effect in 2004 (dry) Sites homogeneous at 3 km scale biomass monitoring (1 km line, sampling scheme) soil moisture sampling sun photometer (Agoufou)

  4. Our interest in having the ‘best’ albedo products ! with expert opinions. No dedicated albedo up-scaling exercise done so far or scheduled but high resolution RS data have been and are being aquired, up-scaling has been or will be done for grasses biomass, LAI, soil moisture. If albedo validation approach successful, possibility to generalize to forthcoming AMMA sites (to be discussed with PIs).
