Abstract: A concise overview of the impact of vegetation structure on the radiative transfer within plantcanopies is given. Furthermore, in the context of inverting 3-D RT models against satellite observations the need for speedy, yet accurate and reliable RT simulations over realistic 3-D canopy architectures are highlighted. To this effect, the Monte Carlo ray-tracing model RAYSPREAD makes use of a variance reduction technique, known as photon spreading, and the capability to operate in a multi-processor environment. Verification and benchmarking of the Rayspread model,as well as, a small study regarding the impact that 3-D woody structures may have with respect to the surface leaving BRF field are also provided.
