ADMS 3
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. It was developed by Cambridge Environmental Research Consultants (CERC) of the UK in collaboration with the UK Meteorological Office, National Power plc (now INNOGY Holdings plc) and the University of Surrey. The first version of ADMS was released in 1993. The version of the ADMS model discussed on this page is version 3 and was released in February 1999. It runs on Microsoft Windows. The current release, ADMS 5 Service Pack 1, was released in April 2013 with a number of additional features. Features and capabilities of the ADMS 3 The model includes algorithms which take into account: downwash effects of nearby buildings within the path of the dispersing pollution plume; effects of complex terrain; effects o ...

Atmospheric Dispersion Modeling
Atmospheric dispersion modeling is the mathematical simulation of how air pollutants disperse in the ambient atmosphere. It is performed with computer programs that include algorithms to solve the mathematical equations that govern the pollutant dispersion. The dispersion models are used to estimate the downwind ambient concentration of air pollutants or toxins emitted from sources such as industrial plants, vehicular traffic or accidental chemical releases. They can also be used to predict future concentrations under specific scenarios (i.e. changes in emission sources). Therefore, they are the dominant type of model used in air quality policy making. They are most useful for pollutants that are dispersed over large distances and that may react in the atmosphere. For pollutants that have a very high spatio-temporal variability (i.e. have very steep distance to source decay such as black carbon) and for epidemiological studies statistical land-use regression models are also used. ...

UK Atmospheric Dispersion Modelling Liaison Committee
The Atmospheric Dispersion Modelling Liaison Committee (ADMLC) is composed of representatives from government departments, agencies (predominantly but not exclusively from the UK) and private consultancies. The ADMLC's main aim is to review current understanding of atmospheric dispersion and related phenomena for application primarily in the authorization or licensing of pollutant emissions to the atmosphere from industrial, commercial or institutional sites. The ADMLC is primarily concerned with atmospheric pollutant discharges from regulated emission sites and other fixed sources. Their review and study interests include routine discharges as well as accidental releases or releases cause by operational upsets. Their interests also include modelling dispersion at all scales from on-site short range (including dispersion modelling indoors) to long range distances. The ADMLC does not normally get involved with pollutant emissions from roadway traffic or other non-fixed sources. Nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UK Dispersion Modelling Bureau
__NOTOC__ This page is out of date and should be considered an historic reference only The UK Dispersion Modelling Bureau was part of the Met Office, the UK's national weather and meteorological service. The meteorologists in the bureau are among the UK's leading experts in areas such: * meteorology * air quality studies and forecasting * air pollution dispersion modelling * industrial emissions Consultancy services The bureau consisted of a team of air quality specialists dedicated to providing advice, support, and consultancy service to industry, government, local authorities and private consultants. The team had particular expertise with long and short range atmospheric pollution dispersion modelling using the NAME, AERMOD, ADMS, BOXURB and other dispersion models. The bureau's consultancy services included: * height assessments of industrial stacks discharging airborne pollutants * long-term environmental impact studies of airborne pollutant emissions * scenario modelling ...

List Of Atmospheric Dispersion Models
Atmospheric dispersion models are computer programs that use mathematical algorithms to simulate how pollutants in the ambient atmosphere disperse and, in some cases, how they react in the atmosphere. US Environmental Protection Agency models Many of the dispersion models developed by or accepted for use by the U.S. Environmental Protection Agency (U.S. EPA) are accepted for use in many other countries as well. Those EPA models are grouped below into four categories. Preferred and recommended models * AERMOD – An atmospheric dispersion model based on atmospheric boundary layer turbulence structure and scaling concepts, including treatment of multiple ground-level and elevated point, area and volume sources. It handles flat or complex, rural or urban terrain and includes algorithms for building effects and plume penetration of inversions aloft. It uses Gaussian dispersion for stable atmospheric conditions (i.e., low turbulence) and non-Gaussian dispersion for unstable condit ...

United States Environmental Protection Agency
The Environmental Protection Agency (EPA) is an independent executive agency of the United States federal government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its administrator, who is appointed by the president and approved by the Senate. The current administrator is Michael S. Regan. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank. The EPA has its headquarters in Washington, D.C., regional offices for each of the agency's ten regions and 27 laboratories. The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of environmental laws, in consultation with state, tr ...

Northern Ireland Environment Agency
The Northern Ireland Environment Agency (NIEA) is an executive agency within the Department of Agriculture, Environment and Rural Affairs (DAERA). It is responsible for conservation of Northern Ireland's environment and natural heritage. Originally part of the Department of the Environment (DOENI), the agency was called the Environment and Heritage Service (EHS) until 1 July 2008, and also had responsibility for the historic environment. On 16 May 2016 the DOENI was dissolved and NIEA became part of DAERA. At the same time, the historic environment functions of NIEA were transferred to the Department for Communities. NIEA is responsible for a range of protected areas in Northern Ireland, including eight areas of outstanding natural beauty, 47 national nature reserves, 43 special areas of conservation, and 10 special protection areas. The NIEA employs 630 people as of 2020. Equivalent bodies in other parts of the United Kingdom * England: Environment Agency, Natural England ...

Health And Safety Executive
The Health and Safety Executive (HSE) is a UK government agency responsible for the encouragement, regulation and enforcement of workplace health, safety and welfare, and for research into occupational risks in Great Britain. It is a non-departmental public body of the United Kingdom with its headquarters in Bootle, England. In Northern Ireland, these duties lie with the Health and Safety Executive for Northern Ireland. The HSE was created by the Health and Safety at Work etc. Act 1974, and has since absorbed earlier regulatory bodies such as the Factory Inspectorate and the Railway Inspectorate though the Railway Inspectorate was transferred to the Office of Rail and Road in April 2006. The HSE is sponsored by the Department for Work and Pensions. As part of its work, HSE investigates industrial accidents, small and large, including major incidents such as the explosion and fire at Buncefield in 2005.
