The main principle behind ccrtm is\nthat many radiative transfer models can form a coupled chain,\nbasically models that feed into each other in a linked chain\n(from leaf, to canopy, to stand, to atmosphere). It allows the\nsimulation of spectral datasets in the solar spectrum\n(400-2500nm) using leaf models as PROSPECT5, 5b, and D which\ncan be coupled with canopy models as 'FLIM', 'SAIL','SAIL2' and\n'INFORM' for top of canopy reflectance, and with atmospheric\nmodels such as 'SKYL'and 'SMAC' for calculation of top of the\natmosphere reflectance. All models can run in forward mode, and\na selection are invertable (backward simulations) if provided\nwith spectral data.
