Description: A set of radiative transfer models to quantitatively describe the absorption, reflectance and transmission of solar energy in vegetation, and model remotely sensed spectral signatures of vegetation at distinct spatial scales (leaf,canopy and stand). The main principle behind ccrtm is that many radiative transfer models can form a coupled chain, basically models that feed into each other in a linked chain (from leaf, to canopy, to stand, to atmosphere). It allows the simulation of spectral datasets in the solar spectrum (400-2500nm) using leaf models as PROSPECT5, 5b, and D which can be coupled with canopy models as 'FLIM', 'SAIL','SAIL2' and 'INFORM' for top of canopy reflectance, and with atmospheric models such as 'SKYL'and 'SMAC' for calculation of top of the atmosphere reflectance. All models can run in forward mode, and a selection are invertable (backward simulations) if provided with spectral data. Jacquemoud et al 2008 provides a comprehensive overview of these and other models <doi:10.1016/j.rse.2008.01.026>.
