Air Quality Trends and Challenges in Urban Area
Air Quality Trends and Challenges in Urban Area
Session ID#: 159288
Session Description:
Air quality remains a significant public health challenge facing large fractions of the population globally. A wide range of source types and source activity levels couple with variations in meteorology and climate to yield a wide range of air quality challenges in urban areas. This session solicits submissions from observational, laboratory, and modeling studies on the improvements and challenges in urban air quality. Field observations from recent campaigns (e.g., 2018 LISTOS, 2021 RECAP, 2021 TRACER-AQ, 2021 OSCA, 2018 HALO, etc.), using advanced instrumentation, low-cost sensors and remoting sensing, are encouraged. Studies on the underlying causes of air quality trends, such as the recent lack of improvement in some North America cities and increases in ozone pollution in China despite emissions reductions, are of great interest. Laboratory studies for understanding the atmospheric chemical processes of urban emissions and their interactions with other emissions sources (e.g, wildfires, agriculture, vegetation) are also welcome. Modeling studies that use observations and laboratory data to improve predictive skills of air quality are encouraged. Relevant air quality issues include, but are not limited to, ozone, fine particles, smoke from wild and prescribed fires, and long-term air quality trends.
