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

  6. OMI Average (2005-2006) SO2 burdens over China http://tes.jpl.nasa.gov/uploadedfiles/Eldering_IGARSS_09_v2b.pdf

  8. MODIS • Moderate Resolution Imaging Spectroradiometer • On board Terra (EOS AM) and Aqua (EOS PM) • Captures data in 36 spectral bands • Images the entire Earth every 1 to 2 days • Multitude of uses

  15. 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

  17. Calipso • Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations • Part of A Train • Actively measures global aerosols and clouds • Provides data on altitude of aerosol layers in the atmosphere

  22. 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.
