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).
