Global climate change can degrade future air quality through changes in air pollution meteorology, including changes to ventilation, dilution, and precipitation. Air pollution extremes are often a product of local emissions, meteorology, and chemistry; however, the exact relationship is often difficult to discern due to multicollinearity of meteorological variables, region-specific interactions resulting from irregular topography or chemical regime, and complex feedback processes. Accurate predictions of future air quality require that these interactions be correctly described. This session invites abstracts that present new knowledge of the relationship between meteorology, chemistry, and air pollution, including those using in situ observations, remote sensing, regional and global models, or a combination thereof. Relevant topics include but are not limited to investigations in past and future changes of air pollution extremes, connections between air pollution and modes of variability, feedbacks associated with meteorology and air pollution, and how global climate change may influence air quality.
