| 摘 要： | 介绍了一种利用太阳直接辐射和天空漫射辐射来反演气溶胶光学特性的方法,研究了其算法实现过程.结合太阳辐射计CE318所测得的太阳直射辐照度和天空漫射辐亮度数据,反演获得了晴朗天气下四个波段的气溶胶光学厚度、Angstrom参数、单次散射反照率、散射相函数和偏振相函数.算法的实现为解决光学遥感应用中气溶胶散射相函数和偏振相函数的测量问题提供了一个实用的方法.

| Abstract: | An inverse method is introduced to derive aerosol optical properties by using direct solar radiation and sky scattering radiation.Based on the method,aerosol optical properties including aerosol optical depth, Angstrom exponent,single scattering albedo,scattering phase function and polarized phase function are retrieved from measured data by the sun photometer.A useful method is provided to acquire single scattering albedo,scattering phase function and polarized phase function of aerosol for application on remote sensing. |
