Abstract:

This report describes the procedure for creating a model for the description of radiation in and released from emissive smoke clouds, that is, clouds in which sources of radiation consist of the internal thermal radiation from an ambient medium as well as from isolated flares. The distribution of the flares in the cloud is in a regular, three-dimensional lattice and is uniform throughout. The model is applicable to the spectral region from the near ultraviolet to the microwave. This smoke cloud model can be used in realistic scenes using external atmospheric conditions and the optical and geometric properties of clouds, flares, targets, and a background. The model is designed to allow a wide range of parameter values to be used to quantify the physical, optical, and geometric properties of clouds, flares and targets, and backgrounds. The model contains simple input and output files, and is user friendly in that all parameters are explained with explicit units given for all constants and variables. However, the user of this model has to have some degree of familiarity with the basic concepts of radiometry and thermal physics.
