Micropulse Lidar: polarization of atmosphere - mplps

The micropulse lidar (MPL) is a ground-based, optical, remote-sensing system designed primarily to determine the altitude of clouds; however, it is also used for detection of atmospheric aerosols. The physical principle is the same as for radar. Pulses of energy are transmitted into the atmosphere; the energy scattered back to the transceiver is collected and measured as a time-resolved signal, thereby detecting clouds and aerosols in real time. \n \nFrom the time delay between each outgoing pulse and the backscattered signal, the distance to the scatterer is inferred. Post-processing of the lidar return characterizes the extent and properties of aerosols or other particles in a region.微脉冲激光雷达（micropulse lidar, MPL）是一种地基光学遥感系统，其核心设计目标为测定云体高度，同时也可用于大气气溶胶的探测。其物理原理与雷达一致：将能量脉冲发射至大气中，收集后向散射至收发器的能量并将其作为时间分辨信号进行测量，从而实时检测云和气溶胶。 通过每一次发射脉冲与后向散射信号之间的时间延迟，可推算出与散射体之间的距离。对激光雷达回波进行后处理，即可表征区域内气溶胶或其他粒子的分布范围与特性。
