The air quality monitoring network in Hong Kong operated by the Environmental Protection Department comprises 16 fixed monitoring stations. Enormous air quality data can be collected to: 1. understand air pollution problems in order that cost-effective policies and solutions can be developed; 2. assess to what extent the standards and targets are being achieved or violated; 3. assist the assessment of public's exposure to air pollution; 4. provide public information on current and forecast air quality.
