What is air Dispersion Modeling?
Air dispersion modeling is a scientific technique used to simulate the movement of air pollutants in the atmosphere. It helps predict the concentration and distribution of emissions over time.
The Air Dispersion Modelling study concerns the estimation of the pollutants in the ground-level concentrations due to the operation of the plant to assess its impacts on air quality and to verify compliance with legislative air quality standards.
The estimation is carried out by using theoretical evaluations and predictive models able to simulate pollutant dispersion and transport in the atmosphere and estimate their concentration levels on the ground. To verify compliance with air quality standards simulated ground level concentration must be properly composed with existing air quality background levels, obtained through proper analysis of the current air quality (before operation situation) to be gained through the existing ambient air monitoring network.
Assessment of impacts on air quality may lead to the identification of proper mitigation actions to be considered in the project design. The process of air pollution modeling operates in 4 parts (data input, dispersion calculations, determining concentrations, and analysis) (data input, dispersion calculations, deriving concentrations, and analysis). To achieve a meaningful evaluation of the importance of any potential harmful effects, the accuracy and uncertainty in each stage must be recognized and assessed
