摘要
对探测大气气溶胶粒子的激光雷达的关键参数-激光雷达比问题进行了讨论,以一种典型的集合状态(一般大陆型气溶胶粒子)为例,分析计算了几种典型湿度下非球形气溶胶粒子在0.532μm波长上的激光雷达比。发现:粒子的非球形对激光雷达比具有明显的影响。该结果为激光雷达探测对非球形大气气溶胶粒子的测量研究提供了分析依据。
Lidar ratio problem is discussed for atmospheric aerosol particle dectection. Lidar ratios at 0.532μm for slightly non-spherical continental- average aerosol particles are evaluated according to up-to-date database of aerosol optical and micro-physical properties. It is found that the non-sphericality has an obvious impact on lidar ratios. The results could be applied in practical lidar detection of atmospheric aerosol particles
