Air Quality Diffusion Model; Application to New York City

by L.-J. Shieh, P. K. Halpern, B. A. Clemens, H. H. Wang, F. F. Abraham
An experimental multisource air pollution diffusion model based on the Gaussian plume formulation is described. The model incorporates point and area sources, time and space dependence of source strengths, and time and space dependence of meteorological variables. Numerical simulation of the SO2 concentration distribution for New York City on January 11, 1971, agrees favorably with experimental measurements.
