The mathematical formulation of the Boltzmann transport equation for photons within a plant canopy was first developed by Ross. The approach discussed in this paper is based on the formulation of Shultis and Myneni, where a bi-Lambertian scattering model of the canopy phase function was used. While Shultis and Myneni relied on the method of discrete ordinates (S{sub N}) from the neutron transport literature to numerically evaluate the radiative transfer equation for a finite medium, a simpler geometry is considered in this paper, allowing a more analytical evaluation using Chandrasekhar's method.
