An advanced bidirectional reflectance factor model is developed to account for the architectural effects exhibited by homogeneous vegetation canopies for the first orders of light scattering. The characterization of the canopy allows the simulation of the relevant scattering processes as a function of the number, size and orientation of the leaves, as well as the total height of the canopy. A turbid medium approach is used to represent the contribution to the total reflectance due to the light scattering at order higher than one. This model therefore incorporate two previously separate approaches to the problem of describing light scattering in plant canopies, and enhances existing models replying on parameterized formulae to account for the hot spot effect in the extinction coefficient.
