Session 2: Atmospheric Chemistry: Climate and Weather Impacts on Air Quality

Co-Chairs: Abdus Salam and Owen Cooper

Poor air quality is primarily the result of air pollutant emissions and chemistry, but day-to-day changes in weather patterns, short-term climate variability (e.g. ENSO), and long-term climate change directly impact the intensity and longevity of air pollution episodes.  This session will focus on new scientific research that identifies and quantifies the impacts of weather and climate on surface air quality.  As surface air quality is also affected by long-range transport and background concentrations of air pollutants, this session will also explore the impacts of weather and climate on air pollution levels in the free troposphere or at remote surface locations.
