| 摘 要： | 提出一种提高地基离轴拉曼-米激光雷达系统几何因子校准精度的纯气溶胶校正算法.理论分析了算法的解析表达式和误差影响因素，并与Raman-Klett迭代校正算法进行了对比分析.实验表明算法对激光雷达比估计误差具有不敏感特性.同时讨论了算法得到的几何因子廓线对反演气溶胶消光系数的影响，结果表明在同等激光雷达比估计误差下，纯气溶胶校正算法比Raman-Klett迭代校正算法反演得到的几何因子廓线精度高约2倍以上，并能更好地体现与人类活动密切相关的近地面气溶胶分布情况.

| Abstract: | A pure aerosol correction method was presented to improve the calibration precision of the geometric factor profile for ground-based Raman-Mie lidar. Firstly, the analytical expression and the effect factors on the estimation error were analyzed theoretically, and compared with the Raman-Klett repeat correction method. The experiment results show the insensitive property of the pure aerosol correction method to the estimation error of lidar ratio. Then the effect of the determined geometric factor profile on aerosol extinction coefficient profile was further discussed. |
