A Fast and Accurate Numerical Method for Radiative Transfer in the Atmosphere

Comptes Rendus. Mathématique, 2021
To solve the radiative transfer equations for the atmosphere, we turn to an equivalent integral equation which has no numerically singular terms. An iterative scheme is proposed for its solution and convergence is proved.The side effect of this proof is ...
