Abstract :
This paper presents samples of BRDF measured at various locations with Polder/Adeos. It is shown that: (1) the Polder measurements permit reconstruction of the BRDF up to 60-70° viewing zenith angle for all azimuths, (2) directional effects are large, (3) the reconstructed BRDF exhibit large spatial variations
