| 摘 要： | 介绍了一台新型偏振-米散射激光雷达用于探测大气气溶胶和卷云的消光特性及偏振特性。为了验证激光雷达探测性能可靠性,采用了3种方法:一是对偏振-米散射激光雷达主要性能参量指标的测定;二是偏振-米散射激光雷达与同类激光雷达对比实验;三是偏振-米散射激光雷达与太阳辐射计探测光学厚度对比实验。实验验证了该系统性能稳定,对比实验探测结果基本一致,探测数据可靠。2007-02~2007-05,利用偏振-米散射激光雷达取得了合肥地区卷云退偏振比的观测结果。结果表明,卷云的退偏振比随高度增加而呈现上升趋势,在7km~12km高度范围内,退偏比在0.2~0.5之间,其平均值为0.36±0.06。
