遥感技术在灰霾监测中的应用综述

摘要

介绍了灰霾遥感监测的基本原理,论述了基于图像变换的TC法、HOT法和基于反演气溶胶光学厚度的灰霾遥感监测技术,以及造成灰霾天气的秸秆燃烧遥感监测方法.指出卫星遥感技术可以提供大尺度、长时间序列的污染物时空分布特征和变化趋势,以及全球性的大气环境综合遥感数据,是灰霾监测与综合治理的重要途径.%The fundamental principle of remote sensing monitoring haze was described. The topic of discussion included TC method based on image transformation, HOT method and haze monitoring technology by remote sensing retrieved Aerosol optical depth as well as haze caused by straw burning. The results showed remote sensing could supply space-time distribution characteristics and trends of pollutants at large scale and long time series. Remote sensing data of global atmospheric environment was important for monitoring and comprehensive control of haze.
