ADMS 6

World leading software for modelling industrial air pollution

Model input data

Emissions sources

ADMS 6 can be used to assess the effect of emissions from a number of industrial source types:

• Point source e.g. emissions from a stack or vent.
• Area source e.g. evaporative emissions from a tank.
• Line source e.g.emissions from a conveyor belt at a quarry.
• Volume source e.g. fugitive emissions.
• Jet source (directional releases) e.g. emissions from a ruptured pipe.

The maximum number of sources that can be modelled in ADMS 6 is 300. Of these up to 300 may be point or jet sources, and within the limit of 300 up to 30 line sources, 30 area sources and 30 volume sources may be modelled simultaneously.

ADMS 6 uses a built-in mapper for helping to manipulate the emissions data (see the Visualisation tools page for more information).

Meteorological data

Meteorological data is available in ADMS format from a number of suppliers. The advanced ADMS meteorological processor determines the structure of the atmospheric boundary layer based on the input data. Hourly sequential or statistical meteorological data may be input.

Background concentrations

Hourly sequential or averaged concentrations of background pollutants may be included if required.

Model output data[top]

ADMS can give output for up to 25 pollutants in one run, which may be either long-term statistical output or short-term output for each hour or meteorological condition in the input meteorological data. Rolling averages, exceedences and percentile statistics may also be calculated.

Output is given on a grid of receptor points covering a specified area and/or at specific receptor locations. Gridded results can be contoured using the Mapper or one of the included links: Surfer, ArcGIS or MapInfo (see the Visualisation tools page for more information).

Where only a single point source is modelled, ADMS 6 produces output containing detailed plume characteristics, such as plume centreline concentration, plume height, plume spread, etc., which can be graphed using the included ADMS Line Plotter.

Where hills are modelled, there is an option to output the FLOWSTAR flow field, which can be contoured using the included 2D output plotter.

Other individual model options produce specific model outputs; for full details see the model documentation.
