Regional Indicators of Daily-to-Yearly Variability in Background Ozone to Inform Air Quality Standard Setting and Decision-Making
DESCRIPTION: To set and implement effective U.S. air pollution policy, the balance between pollution formed from U.S. anthropogenic emissions versus from natural emissions, and transported into the region must be understood. To assist with this the team will improve the process of understanding regional background variability, scope the application of space based indicators to serve as proxies, and investigate how O3 responds to global warming using ground-based networks, ozonesondes, aircraft, and multi-sensor satellite products.
OUTCOMES: Established collaborations with regional and state air quality managers. Led or co-led cross-team collaborative activities focused on understanding differences in model estimates for background pollution, and understanding sources contributing to pollution episodes over the Eastern U.S., Mutiple studies on individual components of background ozone pollution, on links between air quality and climate, and the role of satellite data in advancing knowledge of these topics.
