摘要
微脉冲激光雷达 (MPL)对云和气溶胶的光学属性的空间分布提供连续自动的观测 ,该系统结构紧凑 ,发射能量对人眼安全 ,其可靠性已在国内外很多大型试验中得到了验证。文章介绍了微脉冲激光雷达的系统结构、工作原理以及较之传统激光雷达的优越性 ,给出了气溶胶光学属性的反演方法 (斜率法、近端解法、远端解法和迭代求解法 )并指出了其优缺点 ,对MPL在边界层、气溶胶观测等方面的应用研究成果做了简介。
Micro-Pulse Lidar (MPL) systems provide continuous, automatic observation of nearly all significant atmospheric clouds and aerosols. Being compact in structure and with eye-safe transmitted radiation, the systems proved reliable in a number of experiments both at home and abroad (such as ACE-2 and Aerosols99). An introduction to the structures and working principles of MPL systems, as well as their advantages over traditional ones, are given. The retrieval methods of lidar-determined aerosol optical properties (such as slope, near-end, far-end and iteration methods) and their advantages and disadvantages,and a summary of application researches of MPL to ABL and aerosol measurement, etc., are presented.
