Light Scattering by Leaf Layers with Application to Canopy Reflectance Modeling: The Scattering by Arbitrarily Inclined Leaves (SAIL) Model

摘要

The scattering and extinction coefficients of the Scattering by Arbitrarily Inclined Leaves (SAIL) canopy reflectance model are derived for a fixed arbitrary leaf inclination angle and a random leaf azimuth distribution. The SAIL model includes the Suits uniform model as a special case. Agronomic variables like the leaf area index and the leaf inclination distribution function are input parameters. It provides more realistic angular profiles of the directional reflectance as a function of the view angle or the solar zenith angle than the Suits model.
