A Fast Algorithm to Calculate the Photonflux in Optically Dense Media for Use in Photochemical Models

摘要: A photon flux model is described which determines the photodissociation coefficients for simulation of atmospheric chemistry with a very fast algorithm. Emphasis laid on calculation radiative transfer in optically thick media, e.g. clouds. The concept Kubelka and Munk [1] has been adapted to conditions. algorithm detail, general aspects clouds are presented. To prove accuracy algorithm, results compared those gained by more sophisticated model.
