Air quality models use mathematical and numerical techniques to simulate the physical and chemical processes that affect air pollutants as they disperse and react in the atmosphere. Based on inputs of meteorological data, source information (i.e. emission rates, stack height, exit gas temperatures, flows, and velocity, air dispersion models can characterize primary pollutants (i.e. oxides of nitrogen, carbon monoxide, sulfur dioxide, fine and course particulate matter) that are directly emitted into the atmosphere and secondary pollutants (ozone) that are formed from complex chemical reactions in the atmosphere.

These air dispersion models can be also used for odour dispersion modelling. AUSPLUME Model Ausplume, developed in 1986, is now a regulatory plume dispersion model in Australia. Using Ausplume dispersion model, the ground level concentration of any pollutions or odours emitted from different sources: point sources (like stacks), area sources and volume sources, can be predicted. To predict the impact of a source, the information about the sources, meteorological data, receptor information and topographic data are the major requirements for modeling.

Themes: Air A joint report by the EEA and the European Commission, DGXI Publish date: 28 May 1998 Published by: EEA (European Environment Agency) Annex 5.1 URBAN DISPERSION MODELS This annex documents simple models for first estimation or screening. An urban area contains thousands, or even millions, of individual sources. The application of a diffusion model to each source is impractical. Consequently most of the small sources are combined into larger area sources of strength Q a (mass per unit time per unit area), and it is assumed that the emissions from the ground surface are uniform over that particular area. Diffusion from the largest point sources can be calculated individually and the resulting concentrations at a receptor point can be added to the contribution from the area sources. A.

Legal Notice Air Dispersion Modelling Cti offers an air dispersion modelling service using the latest ADMS-3 software. Air dispersion modelling is used to predict ground level pollutant concentrations in an area around the source(s). The results are presented as concentration contour plots, which can be used to identify areas of unacceptable impact. Modelling is more expensive than simple stack height calculations, but becomes a very cost-effective approach in the following circumstances: where simple calculations result in excessively high stack heights that would be expensive to install; where multiple discharges from stacks and vents are present; where a better understanding of the impact of discharges is required, e.g. if the company is located near a Site of Special Scientific Interest; where management controls are needed to minimise odour impact. The model determines the conditions under which odour complaints are likely to occur, which can be used to plan a mitigation strategy;

DEVELOPMENT OF AN AIR DISPERSION MODEL FOR COASTAL ZONES AND COMPLEX TERRAINS Dr. D.Y.C. Leung Department of Mechanical Engineering Introduction Various methods have been devised for the prediction of atmospheric pollution, which lead to over 100 types of model for different applications. The Gaussian air dispersion model, or its various segmented plume and puff advection progeny, is the most popular and widely adopted model in the world. These models, however, often fail to predict accurately under complex wind and turbulence patterns found in coastal zones and complex terrains such as those presence in Hong Kong and some other similar cities in the world. This study concerns about the development of a powerful air dispersion model for Hong Kong to replace traditional Gaussian models. Objectives Due to the inadequacy of the Gaussian models to predict the complex situation in Hong Kong, there is a genuine need to develop a more powerful and accurate air dispersion model for Hong Kong. Thus the main objectives of this project are: To develop a powerful and accurate air dispersion model to suit the complex topography of Hong Kong, and

Sustainability and Strategic Environmental Planning Air dispersion modelling represents the most effective means of predicting air pollution impacts associated with regional, local and/or specific industry emissions at locations surrounding the source. Dispersion modelling is a specified requirement of virtually all environmental authorities for licensing compliance and development approval applications. In addition to assessment of the spatial extent of pollutant concentrations and compliance with regulatory limits/guidelines, the pollutant concentrations calculated by the model may be used to assess important operational aspects such as the relative contribution of individual sources, the effects of important release parameters such as stack height, temperature and velocity, as well as management options such as changes to operating hours or equipment operation. Air dispersion modeling has several advantages over ambient air monitoring, including:
