Abstract :
Results are presented of spectral directional-hemispherical reflectance data derived from multi-look angle airborne imagery over HAPEX-Sahel in 1992, along with the spatial distribution of BRDF parameters for a kernel-driven model. The results and techniques discussed are relevant to albedo derivation from data of this sort from both airborne and forthcoming satellite sensors
