Title: Estimating Leaf Area Index For Canopies Using Coverage Processes
Author: Garcia N.L.
Abstract: One measure of canopy structure is the leaf area index (LAI, leaf area by unit ground area). Direct measurements are hard to get and indirect measures are based on the relationship between radiation penetration and foliage area. A theoretical model based on azimuthal averages has been widely used. Considering the spatial structure of the canopy, we model it through a coverage process and show that the azimuthal average model subestimates LAI when the canopies are not homogeneous. © 1999 VSP.
