As a weather pattern, the Asian monsoon impacts the lives of more than a billion people. With rapid population and economic growth across the monsoon region, it becomes a pressing concern that the monsoon convection coupled to surface emissions is playing a significant role in the region’s air quality. The uplift of pollutants also enhances aerosol–cloud interactions that may change the behavior of the monsoon. The chemical transport effect of the monsoon system is seen from satellites as an effective transport path for pollutants to enter the stratosphere. The monsoon system is therefore relevant to scales and processes bridging regional air quality, climate change, and global chemistry-climate interaction. The scientific scope of the session includes a) the impact of Asian monsoon, coupled to local emission on air quality, (b) Aerosols, clouds, and their interactions with the Asian monsoon, (c) the role of the monsoon dynamics and convection on chemistry and chemical transport in the Upper-Troposphere Lower-Stratosphere. Both observations and model analyses on related topics are welcome.
