Use of Earth Observation in support of major sport events: case study for the Athens, Beijing and London Olympic Games

摘要

This research provides suggestions for more effective air particulate pollution control policies by government. Inhalable particulate matter (IPM) samples PM0.3, PM3 and PM5 were taken in heating season from 2007 to 2010 in order to determine temporal and spatial variations of IPM concentration based on the indicator Kriging of Geostatistics. Meanwhile, the correlation between IPM and meteorological factors was discussed; the influences of different factors on pollutant concentration were compared.
