The plume visibility model (PLUVUE) is designed to predict the impacts of a single emissions source on visibility in Federal Class I areas. The objective of the model is to calculate visual range reduction and atmospheric discoloration caused by plumes consisting of primary particulates, nitrogen oxides and sulfur oxides. The model uses the Gaussian equation for transport and dispersion. The spectral radiance is calculated for views with and without the plume to calculate other parameters related to perceptibility and contrast reduction. Plume optics calculations are made for two modes, plume-based and observer-based. Four types of calculations can be performed at each downwind distance: effects for horizontal lines of sight with a clear sky background; effects of the plume on horizontal views with white, grey or black viewing object; views looking down the plume centerline toward the source.
