Scalar multiple scattering model for remote sensing applications

The scalar radiative transfer model based on multiple scattering theory is presented. The method of successive orders is applied to solve the radiative transfer equation separately for each scattering order, when assuming Lambertian surface reflectance. It is shown that the presented multiple light scattering model provides us with an accurate atmospheric correction, and that the spectral upward and downward radiances as well as the radiative fluxes can be calculated with a sufficient accuracy. The computational effort when processing remote sensing data may be significantly minimized, because only 2 scattering orders have a measurable contribution to the detected radiation characteristics.
