Air pollution in Asia 

Air pollution is of great concern by the public and government in Asia, specifically in India and China, due to the risk to human health. To elucidate the formation mechanisms of air pollution in Asia, numerous field studies and modelling studies have been conducted in different Asian countries in the recent years, accompanied by mandatory emission restriction strategies that have been put into action.
This session aims for presentations about recent results from field studies, and also air quality monitoring activities in Asia linked to photochemistry, aerosols, emissions of air pollutants and tropospheric chemical composition.
All stages of data analysis are welcome in this session, including presentations of early field data, modelling studies, and results on the global impact of air pollution in Asia.
