1. An Outline for future Pearl River Delta – Hong Kong Air Quality Monitoring Research Projects CS Kiang College of Environmental Sciences Peking University

2. PRD Air Quality Problems The Pearl River Delta River Economic Zone and Hong Kong are suffering from deteriorating air quality: fine particulate matters and ozone are the major culprits

3. PRD Air Quality Problems Highlights of some proposed projects are: aircraft measurement, mobile van laboratory, modeling, atmospheric chemistry, mobile sources from auto emissions These projects aim to compliment on-going programs in PRD and HK Ultimate goals: sustainable growth and cleaner environment for PRD and HK

4. Aircraft Measurements Key Partner: James Meagher from the Aeronomy Laboratory of NOAA Key Mission: Developing a capability in China to use instrumented aircraft for air quality studies Application of instrumented aircraft for measurement intensive PRD study

5. NOAA WP-3D Research Aircraft

7. NOAA WP-3D Gas-phase Measurements

8. NOAA WP-3D Aerosol & Radiation Measurements

9. NOAA Research Vessel Ronald H. Brown

11. NOAA R/V Ronald H. Brown Measurements

12. NOAA R/V Ronald H. Brown Measurements

13. Mobile Van Laboratory Key Partner: Charles Kolb, Aerodyne Research, Inc. Key Features Participating in a long-term PRD regional air quality study Mobile Lab Capabilities Fast response instrumentation Fine particulate measurement Fast response SF6 sensor from WSU to allow tracer flux ratio measurements for point or area emission measurements

14. Atmospheric Chemistry Key Partners: Paul Crutzen Mario Molina and Luisa Molina … will be helping out on the atmospheric chemistry

15. Modeling for PRD Air Quality Key Partners: Ted Russell – reverse modeling – vital for emission inventories verification and regional air quality forecasting David Streets – STEMP model – regional air quality modeling and forecasting

16. Mobile Sources Key Partners: Arnold Howitt, Harvard University Carlos Wing-hung Lo, Hong Kong Polytechnic University Controlling Motor Vehicle Pollution in Southern China: Institutional and Policy Issues

17. Other issues/projects How to involve local research institutions and governments in PRD and HK Planning/funding issues Other important projects: Ground base ozone monitoring and forecasting VOC and NOx measurement Intensive particulate measurement and speciation Persistent toxic substance monitoring Health study and data LIDAR and aerosol optical depth measurement Major sources characterization, e.g., power plants Emission inventories updating and verification Data exchange and sharing

18. Thank you Monitoring Stations in PM2.5 (filter and continuous) and gaseous species Measurements Dynamic Emission Inventory – Observation Establish PRD regional budget in space and time Intensive Measurements Measurements in Mobile platform Aircraft measurements Air Quality Forecast

19.  Develop Regional Monitoring Network and Regional Standard Model  Develop Regional Data management System  Develop Regional Emission Inventory in Time and Space  Develop Validation/accountability system  Establish Regional “ Critical Loading ”  Develop “ off-set ” technology  ***Establish Guangdong-HK- Macau Regional Air Resource Board
