Ozone has long been a key air pollution problem in Hong Kong. Despite many efforts from the government on controlling the primary emission, the secondary pollutant, O3, has been increasing in the past twenty years. This project aims to investigate the frequency and extent of ozone episodes in the past years in Hong Kong, and to study the effect of meteorology and air pollutant transport on ozone episode.
? Literature review and background study
? Analysis of air pollutant concentration data (including CO, NO, NO2 and O3) from air quality monitoring stations of the Environmental Protection Department of Hong Kong
? Analysis of meteorological data (solar, wind speed and direction, etc.) from the Hong Kong Observatory
? Comparison of air pollutant data between urban and suburban site during ozone episodes
? Investigation of air mass transport by using Hybrid Single Particle Lagrangian Integrated Trajectory Model (HYSPLIT)
The applicants are expected to learn:
1) basic knowledge of air pollution and photochemical smog;
2) the methodology of data analysis and some data processing software;
3) analytical skills and critical thinking ability.
