Wolcome to OpenAlea RATP’s documentation#
The model RATP (Radiation Absorption, Transpiration and Photosynthesis) was designed to simulate the spatial distribution of radiation and leaf-gas exchanges within vegetation canopies as a function of canopy structure, canopy microclimate within the canopy 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 (e.g. foliage of several plants) 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. The model typically operates at a 20 to 30 min time step. Principes and main equations of the RATP model are given in: [Sinoquet2001].
The RATP version 2 is basically implemented as a set of Fortran90 modules, which can be used as a Python library in the OpenAlea environment. A Fortran90 module includes public variables and subroutines, which are all accessible in the OpenAlea environment.
