Review of the urban aerosol retrieval research based on high-resolution images

CAO Yongxing;XUE Zhihang;State Grid Sichuan Electric Power Research Institute;  
This paper describes the influence of aerosols on global climate change and air pollution situation,points out the importance of using high- resolution satellite images for urban aerosols inversion,elaborates the research status of the satellite remote sensing retrieval of aerosol,and briefly introduces the principle of satellite remote sensing retrieval of aerosol,and the single channel and multi- channel method,the contrast method based on differences in the spatial structure,the inversion method based on multi- angle data,the inversion method based on polarization data and the inversion method based on laser radar satellite data,which constitute five kinds of satellite remote sensing inversion method widely used nowadays. According to the inversion method and the difficulties of the urban aerosol inversion,the inversion of aerosol in urban areas is analyzed and summarized,with a detailed discussion on the shortcomings of current inversion methods based on high- resolution images of urban areas and a forecast of breakthrough points and the solutions of the existing problems.
