Reflectance measured at a series of phase angles can be used to model the photometric properties of the surface material and estimate physical properties like the surface roughness, surface soil compaction, and
2) is always acquired in the forward scattering direction from one sensor and the backward scattering direction from the other sensor. Bi-directional effects are typified by higher reflectance in the backscatter direction than in forward scatter direction due to shadow hiding (except for specular ...

Therefore, light scattering by aerosols is likely more efficient at shorter wavelengths, meaning that aerosols tend to scatter more blue light (shorter wavelengths) than red light (longer wavelengths). Moreover, one can note that AERONET measurements are included within the variability of the WaltR...
