When applied to plant canopies, classical radiation theory for a turbid medium yields relatively simple expressions for average fluxes of absorbed radiation within an arbitrary volume of vegetation. However, due to the effects of shading and leaf angle, these averaging volumes usually contain a continuous distribution of leaf-level radiative fluxes ranging from full sun to full shade. These distributions are obscured within turbid media models and are thus usually not considered directly unless a computationally expensive leaf-resolving model is used. Consideration of the full probability distribution of absorbed radiative fluxes can yield valuable information about interactions between plant structure and function, not only for radiative fluxes but also for fluxes of radiation-dependent biophysical processes such as photosynthesis. This work presents the theoretical derivation of probability distributions of absorbed direct, diffuse, scattered, and total radiative fluxes for homogeneous canopies with varying structure. The theory is verified against predictions of a three-dimensional leaf-resolving model, and used to explore the impacts of canopy structure on the distribution of absorbed radiation.
