Abstract :
The surface reflectances derived from POLDER/ADEOS are operationally composited in time using an algorithm of adjustment of a BRDF (Bi-directional Reflectance Distribution Function) model against POLDER directional reflectances. This paper compares several linear BRDF models as candidates for this algorithm. The various models are tested and compared against a variety of BRDF field data, and several criteria are examined
