ccrtm - Coupled Chain Radiative Transfer Models
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
