Radiative transfer in vegetation canopies with anisotropic scattering

摘要: Abstract The governing equation and various leaf models for photon transport in vegetation canopies that scatter anisotropically are presented. For idealized leaf-angle distributions simple canopy scattering models, the general its azimuthal average shown to reduce standard forms encountered radiative transfer particle problems. In general, however, descriptions not directly applicable A realistic anisotropic non-rotationally invariant function is examined exact derived. variant of discrete- ordinates method then proposed solving numerically. Finally, numerical results a variety agricultural compared with theoretical measured results.
