Air Quality Dispersion Modelling

If your business is submitting a permit application or planning applications for alterations or extensions of your current site, air dispersion modelling can predict any future issues.

You can use the output from air quality dispersion modelling to determine the air quality impact from existing and proposed industrial installations. Air dispersion models estimate the pollutants emitted by sources such as industrial plants, traffic, and accidental chemical leaks. They can also help you to predict concentrations for future changes in emission sources.

The modelled outputs can be compared with environmental limits and human health air quality limits and will allow you to comply with regulations and explore the effects of different solutions. If the predicted emissions cause a breach of the air quality standards, our expert consultants can help you explore various solutions. 

The technique uses mathematical representations of parameters, such as weather conditions and effects of topography, to characterise the atmospheric processes that disperse pollutants emitted by a source.  

Typical applications of air quality dispersion modelling include:

• Determining air quality impact on existing and proposed industrial installations
• Assessing against air quality standards and limit values
• Determining stack height
• Odour modelling
• Environmental impact assessments
• Support a planning application
