A Computer Simulation Model of Outdoor Radiant Lighting.

Abstract

A deterministic computer model of outdoor daytime (nighttime) radiant lighting is described for a clear sky and slight ground-level haze. Equations are developed for the radiance at an observer's position, which is emitted from a target and the surrounding background. The equations are a function of the positions of the sun (moon), the target and the observer. The equations include the effects of atmospheric attenuation, the background sky light, and the ground cover. The computer model was developed for use in simulation studies of target visibility.
