摘要随着经济的发展，这几年雾霾也变得日益严重，尤其是华北地区，雾霾的增多影响了空气质量，危害着人类的健康。因此，对雾霾的监测与防治迫在眉睫。早在上世纪七十年代，科学家就开始通过遥感手段对雾霾进行分析与监测，迄今为止，已经取得了一定的研究成果。本次研究旨在利用MODIS中分辨率影像数据对华北地区雾霾范围及程度进行研究，达成遥感监测。我们对MODIS定标辐射数据进行反演，通过目视解译得出了霾的范围，再利用对气溶胶光学厚度进行反演，得到了研究区域的气溶胶光学厚度遥感影像，经观察研究，设定AOT阈值为1，从而得到了大于阈值的区域可能存在霾，并与地测气象数据等进行比对，完成了对华北地区雾霾天气的遥感监测。75804

Remote sensing monitoring of haze in North China
Abstract With the development of economy,haze has become increasingly serious in recent years,especially in north China。The increase of the haze impacts air quality as well as do harm to the human health。As a result,the detection and control of the haze is imminent。In the early 1970s,scientists began to analyse and detect haze by means of remote sensing。So far it has made certain research results。The aim of the study is to do research into the haze scope and degree in north China with the MODIS image data for remote sensing detection。We did inversion with the MODIS radiation calibration data then obtained the aerosol optical thickness of remote sensing image of the research area。Seting that the AOT threshold value is 1,we can find that haze may occur in the area which is greater than the threshold。Then we compared the measured meteorological data and finished the remote sensing detection to north China。
The paper has shown 5 figures, 6 tables，26 references。
