探测大气温度和气溶胶的瑞利-拉曼-米氏散射激光雷达

Rayleigh-Raman-Mie Lidar for Atmospheric Temperature and Aerosol Profiles Measurement

研制了一台瑞利-拉曼-米氏散射激光雷达,实现了对流层和平流层大气温度和密度的探测。作为多参数大气探测系统,该激光雷达也实现了夜间至25km、白天至5km高度气溶胶的探测能力;其中激光雷达是探测平流层气溶胶最有效的手段之一。利用该激光雷达对目前合肥地区对流层温度、平流层逆温现象、对流层和平流层气溶胶做了探测和分析,并给出若干典型结果。分析表明,该激光雷达数据可靠,可用于大气温度、密度、气溶胶的常规观测和分析研究。

A Rayleigh-Raman-Mie Lidar（RRML） has been developed for measuring atmospheric temperature,density and aerosol profiles.As a combined system,RRML has the ability to measure aerosol and cirrus up to 25 km at night and 5 km during daytime.Especially,lidar is the most efficient method in measuring stratospheric aerosol.Using RRML system,the change of tropospheric temperature,the inversion layer at stratosphere and the background aerosol at stratosphere has been detected in Hefei,China.The results indicate that measurements of RRML are reliable,and RRML can be employed for the routine observations and the analysis of atmospheric temperature and aerosol.
