摘要

The 16th Asian Games and the 10th Asian Para Games were held in Guangzhou, China during November to December 2010. Strict controls on pollutant emissions and motor vehicle traffic were imposed on Guangzhou and neighboring cities to improve the air quality in and around the city. Satellite data were used to examine the impact of the 2010 Asian Games and Para Games on regional air- quality. As local environmental protection agencies in China are only required to publish the daily levels of the dominant air pollutant among respirable particulate matter (PM_(10)), sulfur dioxide (SO_2), and nitrogen dioxide (NO_2), we mainly analyzed these three major air pollutants from satellite observations. PM_(10) were derived from MODerate resolution Imaging Spectroradiometer (MODIS) and ground measurements. SO_2 were measured with the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY) instrument on ENVISAT, and NO_2 were retrieved from the Ozone Monitoring Instrument (OMI) onbroad EOS-Aura. retrieved from satellite measurements over Guangzhou showed -0.87 mg/m~3/per day reduction during October to December. SO_2 retrieved from satellite measurements over Guangzhou showed -0.01 DU/per day reduction during October to December. NO_2 retrieved from satellite measurements over Guangzhou showed -19.5 × 10~(13) mol/cm~2/per day reduction during November. Thus, based on satellites observations alone, noticeable reductions in these pollutant tracers were measured during both games.
