Assessing Potential Climate Change Impacts on Local Air Quality Using AERMOD

Model results in this study show that the modelled maximum ground level concentrations could vary significantly with the choice of meteorological data periods and source configurations, mainly due to changes in the climatology of wind speeds, their distribution and temperature. Modelled maximum ground-level concentrations could vary by as much as 30% during the historical period (1996–2016), and could decrease by over 50% for most low-level sources in the future (2051–2055) with projected climate change.
