摘要
多波长拉曼偏振大气探测激光雷达是用于大气气溶胶、水汽探测及特性研究的有效工具。介绍北京遥测技术研究所自行研制的多波长拉曼偏振大气探测激光雷达系统,激光发射系统发射355nm、532nm、1064nm波段激光,信号采集系统采集大气分子、气溶胶的弹性后向散射信号以及N_2、H_2O的拉曼后向散射信号。利用多波长拉曼偏振大气探测激光雷达在河北省望都县交通局绿化基地对京津冀地区气溶胶进行观测,通过反演获得该地区大气气溶胶、水汽垂直方向时空分布廓线。通过本次观测,可有效探测大气气溶胶层、云层的光学及物理性质,有助于研究气溶胶、云对气候变化和对天气演变的影响。
The Atmosphere Multiwave raman Polarization Lidar Equipment （AMPLE） is an effective tool for the detection and study on characteristics of atmospheric aerosol and water vapor. This paper introduces the AMPLE system which is manufactured by Beijing Research Institute of Telemetry. The laser emission system emits three wavelengths＇ laser whose wavelengths are 355nm, 532nm and 1064nm. The signal collection system collects the elastic baekscattering signal from atmospheric molecule ＆ aerosol, and the raman backscattering signal from N2 ＆ H2O. The AMPLE is used to detect the aerosol in the green base of traffic bureau, Wangdu, Hebei. We can obtain the spatial-temporal vertical profile of atmospheric aerosol and water vapor in this district. We can effectively detect the optical ＆ physical properties of atmospheric aerosol layers and cloud layers through this observation. It is help- ful to study the effects of aerosol and cloud on the climate change and weather evolution.
