Application of remote-sensing technology in atmospheric environmental assessment

In this study, remote-sensing technology was applied to investigate the air pollution concentration distributions in the area of Shajiao Power Station in Guangdong Province, China. Based on the analysis of satellite physical mechanism of remote-sensing information, a model for remote-sensing identification and processing of emitted gas was established in order to extract information about pollution diffusion. It is the first time in China that the accumulative concentration information was retrieved from TM Satellite data. The image shows pollutant distribution and impact area clearly. The method is useful in area atmospheric environmental quality survey.
