A STOCHASTIC CANOPY MODEL OF DIURNAL REFLECTANCE

摘要

The spectral signature of most vegetation varies with both direction of view and time of day. This variation is spectrally dependent and is due primarily to differences in canopy geometry. As a means of investigating the interaction of shortwave radiation with vegetation a stochastic canopy model was developed. The model uses random variables based on measured distributions for incoming radiation flux, intrinsic optical properties, and canopy geometry.
