Remote Sensing of Pollution in China Dan Yu December 10th 2009
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
Population Density www.temis.nl
Select Remote Sensing Tools Considered: • OMI • MOPITT • MODIS • SeaWiFS • Calipso • SCIAMCHY
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
OMI Average (2005-2006) SO2 burdens over China http://tes.jpl.nasa.gov/uploadedfiles/Eldering_IGARSS_09_v2b.pdf
