Abstract : This report describes the theoretical basis for the smoke obscuration model ACT II. The work encompasses analytical procedures for determining smoke concentration, temperature, path integrated concentration, path radiance, path luminance, target and background radiance, target-background luminance, and contrast transmission. The model includes both single scattering and thermal emission and is applicable for wavelengths from the visible through the infrared. Data from Smoke Week II are used to present an example of input/output. (Author)
