USE OF EARTH OBSERVATION IN SUPPORT OF MAJOR SPORT EVENTS: CASE STUDY FOR THE ATHENS, BEIJING AND LONDON OLYMPIC GAMES

摘要

Inhalable particulate matter (IPM) is one of the principalrnpollutants in Beijing. Sand weather in spring and winterrnseasons partly because of regional airflow, in most casesrnit is results from autochthonic pollution, especially inrnheating season of winter. In this paper, the law ofrntemporal spatial distribution of IPM and the relationshiprnbetween IPM and influence factors were studiedrncombing RS techniques with ground-based monitoring.rnThe change of underlying surface which were obtainedrnfrom high resolution Remote Sensing images in differentrnperiods was analyzed; the content of different diameterrnof particles were collected by ground observationrninstrument and chemical composition were analyzed; thernrelationship of distribution of IPM and underlyingrnsurface was studied using spatial analysis of GIS. Thernresults indicate that the pollution distribution of IPM hasrna very close relation with underlying surface, man-madernpollution sources, population density and meteorologicalrnfactors.
