[100.05] 3-D Radiative Transfer

M. P. Egan, R. F. Shipman (Phillips Laboratory/GPOB)

We have developed a Monte Carlo simulation of radiative transfer for three-dimensional geometries, with internal structure. Both internally and externally illuminated cases can be modeled. The code solves multi-frequency continuum radiation transport using an "energy bundle" method to reduce the number of photon paths it is necessary to follow. The photon path mathematics are computed independently of the coordinate system imposed by the cloud geometry. This allows greater latitude in our choice of cloud morphology. To demonstrate the validity of the 3-D model we shall compare its results to those of a 1-D finite-difference model for the case of a spherical cloud. Results for non-spherical models will also be presented.
