Abstract	:	This paper models the effects of the leaves of mature broadleaf trees on air-to-ground free-space optical (FSO) communication systems operating through the leaf canopy. Ecological radiation transfer models are considered and the concept of Leaf Area Index (LAI) is reviewed and related to a probabilistic model. Leaf transmittance is experimentally measured for different leaf types and determined to be very close to zero. A probabilistic canopy model of foliage is developed as obscuring leaves are randomly distributed throughout the treetops. The expected fractional unobscured area statistic is derived as well as the variance around the expected value. Monte Carlo simulation results confirm.............-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
