基于遥感的上海地区雾霾监测研究

摘要

Taking the Moderate Resolution Imaging Spectroradiometer (MODIS) remote sensing data as the data source ,this paper carries a continuous monitoring of haze pollution by using second simulation of satellite signal in the solar spectrum (6S) and NASA V5.2 algorithm ,and analyzes the causes for Shanghai area on December 4 ,2013 to December 8 ,2013 .The result shows the haze pollution of Shanghai area is mainly formed by the local production and nonlocal migration .The aerosol optical depth (AOD) achieves the maximum on December 6 ,thus the area of haze pollution covers from northwest to southeast and the level of pollution gradually falls .%以中分辨率成像光谱仪（MODIS）遥感数据为数据源，综合利用6S传输模型与NASA V5.2算法对2013年12月4日至8日上海地区雾霾污染进行了连续性监测，并对其形成原因进行分析。结果表明，此次雾霾污染主要是由本地生产和外地迁移来源共同作用形成，上海地区气溶胶光学厚度在12月6日达到最大，雾霾污染区域逐渐从上海地区的西北向东南扩散，污染等级也逐渐降低。
