Paper Abstract

Beijing is the host city of the 2008 Olympic Games. One of the most important and urgent things is to improve the air quality in Beijing in order to have a "Green Olympic". The monitoring of air pollution concentration and distribution are the keys to evaluate the air quality and to adopt effective control strategies. Remote sensing from space has given us a new view to study air pollution in describing the aerosol distribution for a large coverage. As the aerosol optical thickness (AOT) indicates the atmospheric turbidity over urban areas, satellites with high space resolution provide the possibility to monitor urban air pollution through retrieving the AOT. Based on radiative transfer theory, we have developed an operation bi-angle approach, which can be used to retrieve AOT value over high reflectance land surface. With this bi-angle approach, AOT values around Beijing Olympic area were retrieved from ASTER visible band data acquired on January 27th, 2004 and April 9th, 2004, respectively. Results showed the detailed information of air quality around Beijing Olympic area and that vehicles exhaust and construction cement dusts are major pollutants in this area. From this study, we can conclude that high spatial resolution satellite remote sensing of aerosol properties could serve as an efficient tool for monitoring the source and the spatial distribution of particular pollutants in urban area.
