In the context of this "Air Dispersion Modeling" category, air dispersion models may be defined as computerized mathematical calculations for predicting the dispersion behavior of air pollutants emitted into the atmosphere. The many types of air dispersion models include those for modeling: the continuous emission of buoyant pollutant plumes; the non-continuous accidental releases of either buoyant or heavier-than-air (i.e., dense gas) pollutants; puff emissions; point-source emissions; area-source or line-source emissions; mobile transportation-source emissions; fire and smoke emission models; etc. Air quality models for urban airsheds are probably best placed in the "Air Quality" category rather than in this "Air Dispersion" category. Sources for air dispersion modeling information include governmental agencies, research institutes, university faculty and post-graduate students, environmental consultants, industrial dispersion modeling practitioners, and pollution meteorologists.
Atmospheric Dispersion Modelling
An open source Wiki devoted to atmospheric dispersion modelling. Offers technical articles.
AQM Resource Centre
The Air Quality Management (AQM) Resource Centre is maintained at the University of the West of England in Bristol, England. It provides much useful information, including brief descriptions of many British and USA air dispersion models.
Atmospheric Dispersion Modeling Liaison Committee (ADMLC)
ADMLC's main aim is to review current understanding of atmospheric dispersion for application in authorization or licensing of discharges to the atmosphere from industrial, commercial or other sites. ADMLC is concerned with long-term controlled releases as well as short-term releases, and at all scales, including on-site and within buildings.
Environmental Software and Modelling Group, Technical University of Madrid
Conducts research in modelling and prediction of air quality.
Finnish Meteorological Institute
The activities of the Air Quality Research department at the Finnish Meteorological Institute (FMI) include atmospheric dispersion modeling for: urban air quality, regional and long-range transport, and accidents involving hazardous materials.
The GAIA Air Dispersion Model Database
A database of 27 different air dispersion models. Each model entry includes: a description, where to obtain the software, the original authors, and literature references pertaining to the model. Sponsored by a consortium of 10 countries in Europe, Africa, Asia and Latin America.
Literature References on Mesoscale Meteorology
A comprehensive list of literature references on mesoscale meteorology compiled by Dr. Ming Xue, many of which relate to various aspects of air dispersion modeling.
National Atmospheric Release Advisory Center
Located at the University of California's Lawrence Livermore National Laboratory (LLNL), the National Atmospheric Release Advisory Capability (NARAC) is a national emergency response service for real-time assessment of incidents involving accidental releases of nuclear, chemical, biological, or natural hazardous material.
NOAA's Air Resources Laboratory (ARL)
Within the U.S.'s National Oceanic and Atmospheric Administration (NOAA), the ARL conducts research on the transport, dispersion, transformation, and removal of atmospheric pollutants - leading to the development of air quality and dispersion models. The ARL also supports other U.S. agencies. In particular, the ARL's Atmospheric Turbulence and Diffusion Division (ATTD) and Atmospheric Sciences Modeling Division (ASMD) support the U.S. EPA in developing regulatory air dispersion models.
StadtKlima: The International Association For Urban Climate
A list of air quality and air pollution dispersion models with descriptions, details and contacts for obtaining further information. Most of the listed models were developed in Germany, and the StadtKlima Association is headquartered at the University of Freiburg in Germany.
U.S. EPA's Support Center for Regulatory Air Models
The U.S. Environmental Protection Agency uses this site to provide information on the many dispersion models supporting regulatory programs required by U.S. law. All of the EPA's dispersion models and their Users' Manuals can be downloaded cost-free from here. An online forum is also provided for discussion/questions/answers on all aspects of the EPA's models.
