Overview

The model RATP (aka OpenAlea.RATP) was designed to simulate the spatial distribution of radiation and leaf-gas exchanges within vegetation canopies as a function of canopy structure, canopy microclimate and physical and physiological leaf properties. The model uses a 3D representation of the canopy (i.e. an array of 3D voxels, each characterised by a leaf area density) and allows several vegetation types to be input at voxel scale. Radiation transfer is computed by a turbid medium analogy, transpiration by the leaf energy budget approach, and photosynthesis by the Farquhar model, each applied for sunlit and shaded leaves at the individual 3D cell-scale. Principes and main equations of the RATP model are given in: Sinoquet et al., 2001, Plant Cell and Environment, 24, 395-406.
