Many atmospheric dispersion models are referred to as boundary layer models because they mainly model air pollutant dispersion within the ABL. To avoid confusion, models referred to as mesoscale models have dispersion modeling capabilities that extend horizontally up to a few hundred kilometres. It does not mean that they model dispersion in ...
For those who would like to learn more about atmospheric dispersion models, it is suggested that either one of the following books be read: Turner, D.B. (1994). Workbook of atmospheric dispersion estimates: an introduction to dispersion modeling (2nd ed.). CRC Press. ISBN 1-56670-023-X. www.crcpress.com; Beychok, M.R. (2005).
There are five types of air pollution dispersion models, as well as some hybrids of the five types: [1] Box model – The box model is the simplest of the model types. [2] It assumes the airshed (i.e., a given volume of atmospheric air in a geographical region) is in the shape of a box.
The ADMS 3 (Atmospheric Dispersion Modelling System) is an advanced atmospheric pollution dispersion model for calculating concentrations of atmospheric pollutants emitted both continuously from point, line, volume and area sources, or intermittently from point sources. [1]
The atmospheric component of the CM2.X models employs a 24-level atmosphere with horizontal resolution of 2° in east–west and 2.5° in north–south directions. This resolution is sufficient to resolve the large mid-latitude cyclones responsible for weather variability.
The CALPUFF model is designed to simulate the dispersion of buoyant, puff or continuous point and area pollution sources as well as the dispersion of buoyant, continuous line sources. The model also includes algorithms for handling the effect of downwash by nearby buildings in the path of the pollution plumes.
The AERMOD atmospheric dispersion modeling system is an integrated system that includes three modules: [1] [2] [3]. Graphic display of Aermod output. A steady-state dispersion model designed for short-range (up to 50 kilometers) dispersion of direct air pollutant emissions primarily from stationary industrial sources.
For those who are unfamiliar with air pollution dispersion modelling and would like to learn more about the subject, it is suggested that either one of the following books be read: Turner, D.B. (1994). Workbook of atmospheric dispersion estimates: an introduction to dispersion modeling (2nd ed.). CRC Press.
