AbstractBased on the field measurements of the reflected radiation distribution an sunlit crown surface and crown structure, the analytical approximation model of path-scattering of light in a homogeneous layer is applied to the calculation of the reflectance signature of sunlit crown. The reflectance on the sunlit crown surface is considered as the weighted sum of the direct-to-hemisphere reflectance and the hemisphere-to-hemisphere reflectance. The validation results show that the calculated reflectance signature fits the field measurement very well. This paper presents details of the validation and the feasibility of the model application to nonuniform medium, such as tree crown canopies.
