A two-dimensional model (2DLEAF) of leaf photosynthesis and transpiration has been developed that explicitly accounts for gas diffusion through the boundary layer and the intercellular space as well as for stomatal regulation. This model was developed by Ludmila and Yakov Pachepsky and Basil Acock
The model has been validated for tomato See the manual folder for a manuscript describing the operation and theory
The example folder shows how to run the model
The project file compiles with Intel Fortran in Visual Studio. The program uses some QuickWin elements that can be removed easily
