Light transmittance across smoke plumes downwind from point sources of aerosol emissions
Abstract A new calculation procedure for theoretically predicting the magnitude of light transmittance across a smoke plume downwind of its emission source is presented. The calculation procedure is based on a combination of Mie light scattering theory and the Gaussian (Pasquill-Gifford) plume diffusion equations. Source information needed to estimate the light transmittance through the plume at a given downwind include the meteorological conditions, stack height, gas exhaust temperature and velocity, aerosol emission mass flowrate, size distribution, and refractive index. Graphs of the horizontal plume light transmittance dispersion parameter and the horizontal average extinction coefficient dispersion parameter are presented as a function of the downwind distance. A sample calculation is included to illustrate the procedure and use of the various parameters.
