Modeling the interaction of solar radiation with vegetation elements using the Monte Carlo method

The aim of this work is mathematical modeling of radiation transfer in vegetation cover elements, the geometry of which is close to real, using a software implementation of the Monte Carlo method. Information about the radiation reflected by a plant is needed to model the photosynthetic activity of trees, and consequently to model the carbon dioxide fluxes absorbed or released by plants, which is one of the most important tasks of ecology. By definition, the Monte Carlo method is a method for modeling random variables and processes to calculate the characteristics of their distributions. The process of radiation transfer in inhomogeneous media is modeled as a random Markov chain of collisions of photons with matter, and the purpose of the Monte Carlo method is to find the average statistical characteristics of this process. In this work, a small branch of birch is used as an object. In connection with the possibility of using modern multiprocessor systems for calculations it becomes necessary to distribute calculations, which can significantly reduce the time of realization.
