Photochemical Air Pollution in Highly Urbanized Subtropical Regions: from Micro Environments to Urban-Terrestrial-Oceanic Interactions

This project, led by Prof. Wang Tao, consists of comprehensive research investigating the phenomenon of photochemical air pollution in an urban-terrestrial-oceanic and micro-meso-synoptic paradigm. The major scientific achievements include the discovery of the important role of halogen atoms in the air quality of continental regions, the complex responses of ambient secondary air pollutants to emission changes, and as drivers of long-term trends of ozone (an air pollutant and a greenhouse gas) in subtropical Asia. The findings have yielded new insights into the cause of winter haze in northern China and photochemical smog in southern China. The findings have been shared with news media to promote public awareness of the importance of academic research and the current air pollution.

It won more than HK$33 million funding for Theme-based Research Scheme from the Hong Kong Research Grants Council which was the first TBRS project for PolyU.
