The incoherent scattering model based on radiative transfer theory is adopted and presented in our developed LAGRS-Veg model (Unwin et al. 2024). In the model, the surface vegetation layer can be divided into the canopy layer and the trunk layer. The canopy layer includes leaves and branches. WebIn the case of light, incoherent scattering is called “Rayleigh” scattering when it is elastic. It is a common process that makes us see objects with our eyes, which detect light scattered by these objects. Thus leaves appear green as chlorophyll pigments scatter green light, while it absorbs blue and red lights and is transparent for green light. how many rings does chad henne have
