Remote Sensing of Pollution in China Dan Yu December 10 th 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
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
http://tes.jpl.nasa.gov/uploadedfiles/Eldering_IGARSS_09_v2b.pdf OMI Average (2005- 2006) SO2 burdens over China
MOPITT Measurements of Pollution in the Troposphere Onboard Terra Measure pollution patterns and effects in lower atmosphere –Mainly CO, but can measure methane First to use gas correlation spectroscopy Swaths are 640 km wide
SCIAMACHY SCanning Imaging Absorption SpectroMeter for Atmospheric CartograpHY Onboard ENVISAT Primary Objective: Perform global measurements of trace gases in the troposphere and in the stratosphere.
Conclusions Many remote sensing tools can be used –Many other remote sensors not discussed –Overlaps Strides to reduce pollution in China –Remote sensors will help track progress –Tracking of areas for federal compliance
