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

Hong Kong Winter-Time ROS Campaign, September – October 2016
The Hong Kong Winter-Time ROS Campaign was carried out at the Hong Kong City University, led by Professor Zhi Ning from HK CityU. The project focused on the measurement of the diurnal profiles of PM2.5 and gas-phase ROS concentrations at two different sampling sites. This project was a joint project between Professor Zoran Ristovski from Queensland University of Technology and Assistant Professor Zhi Ning from the City University of Hong Kong, and was funded by a Hong Kong Research Council Grant.
The samples were performed with the latest prototype of the novel real-time PM ROS sampler developed by QUT, the Particle into Nitroxide Quencher (PINQ). Reece Brown, a PhD candidate from QUT, spent two weeks in Hong Kong setting up, calibrating, and performing preliminary samples with the PINQ. The diurnal measurements were then taken over a month long period by Dr Nirmal Kumar, a Post-Doctoral research fellow from CityU. The measurements will provide diurnal trends in PM2.5 and gas-phase ROS concentrations for each day of the week at both roadside and rooftop sampling sites.
This campaign is the winter time partner to the summertime campaign “Hong Kong City University Campaign” from September to December of 2015. Both are part of the project “Semi-volatile particulate matter (PM) species in roadside environment: Role in gas-particle partitioning and formation of oxidative potential”.
