Leaf optical models simulate the radiative transfer interactions of light and leaf biochemical properties. These models allow retrieving leaf biochemical composition and structural characteristics. Implemented leaf optical models:

 

Canopy optical models simulate the radiative transfer interactions of light and canopy structural properties. These models allow retrieving canopy structural characteristics. When coupled with a leaf optical model, these models also allow the retrieval of leaf attributes at the canopy scale. Implemented canopy optical models:

 

Combined radiative transfer models have several sub-models merged into one bigger model, typically including a leaf and canopy optical model. Implemented combined models:

Atmospheric radiative transfer models simulate the radiative transfer interactions of light scattering and absorption through the atmosphere. These models are typically used for the atmospheric correction of airborne/satellite data and allow retrieving atmospheric composition. Implemented atmospheric RTMs:
