1. Remote Sensing of Pollution in China Dan Yu December 10 th 2009

2. Why China? Heavy Industrialization –Large increase in primary energy consumption mainly fueled by coal Large Population –Adverse health effects, premature deaths (3/4 of a million due to air and water pollution) Lack of extensive ground-based monitoring system

3. Population Density www.temis.nl

4. Select Remote Sensing Tools Considered: OMI MOPITT MODIS SeaWiFS Calipso SCIAMCHY

5. OMI Ozone Monitoring Instrument On board NASA Aura Can provide global coverage in a day Measure key air quality components Distinguish between aerosol types Combination of algorithms used to extract data
