Air Quality Models (AQMs) are powerful tools for the investigation of ozone buildup mechanisms, however, due to the complexity and geographic specificity of such models, they can only be used to simulate a limited number of episodes. Meteorological conditions have a large impact on air quality, and selection of representative scenarios under which air quality standards are exceeded is critical to maximizing the knowledge gained from AQM simulations. We use cluster analysis to determine recurring meteorological states using historical data. Categorization of days of the ozone (or PM) season to meteorological regimes permits identification of representative atmospheric conditions favorable to ozone (or PM) buildup.
