The Battlefield Emission and Multiple Scattering (BEAMS) model computes the diffuse radiance fields in 3-dimensional clouds having spatially inhomogeneous concentrations and optical properties. The technique employs 26-stream radiative transfer calculations on a regular grid of aerosol concentrations. Incident illumination sources on the cloud include diffuse illumination, direct illumination, and finite width beam illumination. Volume emission effects as well as reflective and cyclic boundary conditions are also supported. The BEAMS model addresses a need for more realistic treatment of spatial fluctuations in aerosol and particulate clouds. Model comparisons are presented against known conditions, and examples are given of applications to modeling the spatial variability induced in background contrast and scene visualization.
