Research Of Ground-based Remote Sensing Of Atmospheric Aerosols And Regional Characteristics

Through the use of ground-based instruments to study the atmospheric aerosol monitoring network has become a hot study abroad, this paper proposes to use the sun photometer CE318 to study the properties of atmospheric aerosols, the main research contents as follows.(1) CE318-based sun photometer through the indoor and field calibration testing, and calibration results of both methods were compared. At the same time, inversion of the aerosol optical thickness for comparison and found a good linear correlation between the two, you can ensure that the results of inversion of aerosol optical thickness of the reliability and accuracy.(2) For remote sensing of atmospheric aerosol optical thickness retrieval theory, algorithm analysis and accuracy through the use of different software comparison, and then combining MODIS satellite retrieval and global aerosol monitoring network AERONET compare, analyze ground-based inversion and Satellite inverse correlation, and dependability.(3) For Beijing, Shenyang, Fushun, Benxi and other regions to conduct analysis of regional characteristics of atmospheric aerosols, including aerosol optical thickness, Angstrom wavelength exponent, Angstrom turbidity coefficient, the average spatial and temporal trends and impacts.(4) For the future for more effective monitoring of urban atmospheric aerosol properties, proposed to set up Chinese ground-based remote sensing aerosol monitoring network's recommendations.
