Rise in summertime ozone levels in South China: Impacts of long-range transport of Southeast Asia emissions

We will put emphases on chemical characterization of Southeast Asia (SEA) emissions and their aging products in South China, figuring out the occurrence, transport and aging processes of SEA emissions, and quantifying the impacts of SEA emissions on O3 pollution in South China in this project, through analyses of historical data, field observation, and application of box and chemical transport models. The successful completion of this project will clearly reveal the relationships between the rising summertime O3 in South China and SEA emissions.
