Three-Dimensional Radiative Transfer Modeling of Tropospheric Atmospheres

摘要

Physically accurate visualizations of tropospheric atmospheres require three-dimensional (3D) radiative transfer (RT) codes capable of simulating scattering and absorption effects in and around natural clouds. This report describes an adaptation of the discrete ordinates technique for handling both thin (haze) and thick (natural cloud) optical media in a consistent manner. Media are modeled via uniform density cubical scattering cells (assuming that incident diffuse streams have uniform radiance over each input face). These assumptions allow the analytic
