Description
Summary:The USEPA （U. S. Environmental Protection Agency） approved ISC3 for short-range dispersion modeling. The regulatory model of China is a traditional Gaussian plume model similar to ISC. This paper demonstrates the advantages of ISC3 over the regulatory model of China by comparing their predicted ground level concentrations （GLC） along downwind distance to the Alaska tracer field data. The field experiment features buoyant release of effluent at elevated height over a flat terrain and local flows influenced by building downwash. ISC3 shows much better space-time correlation and probability distribution than the China regulatory model, which frequently underestimates the GLC for effluent released with significant plume rise under stable atmospheric conditions. The performance of ISC3 is greatly enhanced by incorporating the state-of-the-art knowledge of boundary layer meteorology. In particular, ISC3 employs the PRIME model for building downwash.
