三波长拉曼偏振激光雷达系统研制及探测个例

大气气溶胶和卷云对地球大气之间辐射收支平衡有重要的影响，主要表现在它们的直接气候效应、间接气候效应以及它们之间的相互作用。为了深入研究大气气溶胶的微物理特性和卷云的物理性质，开发研制了三波长拉曼偏振激光雷达系统，它由发射、接收、控制与数据采集子系统组成。该激光雷达系统具有探测波长多、探测范围大、时间和空间分辨率高、灵敏度高和数据可靠等特点。由该激光雷达的数据可以反演355、532、1064 nm 3个波长上的后向散射系数，355 nm和532 nm两个波长上的消光系数以及532 nm波长上的退偏振比。个例研究结果表明该激光雷达系统数据可靠、可以对气溶胶和卷云进行微物理性质的探测研究。

Abstract

Atmospheric aerosol and cirrus clouds modulate the balance of the radiation budget between the earth and its atmosphere, through their direct, indirect effect and the reaction of each other. In order to study microphysical properties of atmospheric aerosol and physical properties of cirrus cloud, a three-wavelength-Raman-polarization lidar system is developed, which is composed of transmitter, receiver, control, and data acquisition subsystems. It has many advanced characteristics, such as multiply wavelengths, large detecting range, fine temporal and range resolution, good detection sensitivity and reliable data. The backscattering coefficients of 355, 532 and 1064 nm, extinction coefficients of 355 nm and 532 nm, and depolarization ratio of 532 nm can be retrieved from this lidar system. Case study indicates that the data acquired from this lidar are reliable and can be used for study of the microphysical properties of the aerosol and cirrus cloud.
