The SPART model: a soil-plant-atmosphere radiative transfer model for satellite measurements in the solar spectrum
The model uses three computationally efficient RTMs for soil (BSM), vegetation canopies (PROSAIL) and atmosphere (SMAC), respectively. The sub-models are coupled by using the four-stream theory and the adding method. The resulting `Soil-Plant-Atmosphere Radiative Transfer model' (SPART) simulates directional TOA spectral observations, with all major effects included, such as sun-observer geometries and non-Lambertian reflectance of the land surface.
The users are recommended to read the paper that describe the developments and usage of the model.

The model was tested using Matlab 2017a. The users are expected to have the Microsoft installed. The input data are structured in an excel spreadsheet. If there is not Microsoft, it is possible to define the inputs in a script.
The users can run run_SPART.m or any examples in run_SPART_some_examples.m to have a general idea of this model.
