Air Quality Monitoring in Hong Kong, September – November 2016

This sampling campaign is led by Professor Hai Guo from The Hong Kong Polytechnic University (HK PolyU) in collaboration with the Sun Yat-Sen University, National Central University, Queensland University of Technology, Ji’nan University and Hong Kong University of Science & Technology. It is being conducted simultaneously at two sites: a sub-urban site in Tung Chung, Hong Kong and a rural island site in Zhuhai, China. The measurements include canister sampling, real-time monitoring of weather conditions, trace gases, volatile organic compounds (VOCs) as well as other precursors of photochemical ozone production. This will be followed by a comprehensive analysis of the chemical database using a combination of statistical analysis of field observations, mesoscale meteorological simulations, diagnostic and prognostic box models, for example, an observation-based box model, an emission-based model, and chemical transport models. The proposed study will significantly improve our understanding of photochemical formation and transport mechanisms for subtropical coastal regions with complex coupling of meteorology and chemistry, and will advance our knowledge of the atmospheric chemistry in the marine boundary and have wide implications for other subtropical coastal regions. The scientific findings will have direct policy implications for reducing O3 pollution and visibility degradation in subtropical South China.  View more photos
