Abstract :
Summarizes studies on soil radiative transfer. The well-known Hapke model is improved and a new approximation is developed for the multiple scattering calculations. Soil hot spot effects are evaluated using coherent backscattering theory, rather than the shadowing theory that has been widely used for calculating soil and canopy hot spots
