摘要
大气探测激光雷达利用激光与大气的相互作用来主动遥感测量大气参数,在大气科学研究、环境监测、气象预报等领域发挥着越来越重要的作用。大气密度随高度呈指数下降,对流层以上的高层大气密度稀薄,探测难度较高,探测手段较少,探测数据也较少。随着激光雷达技术的发展,激光雷达对高层大气密度、温度、风场等参数的探测能力逐步提高,获得了较为丰富的高时间、空间分辨的观测数据,并应用于中高层大气模式发展、临近空间环境保障等领域。系统地介绍了高层大气激光雷达探测机制、国内相关激光雷达的探测能力及台站建设情况,并对高层激光雷达的发展趋势和应用前景进行了展望。
Based on the interaction between laser photons and atmosphere,light detection and range(lidar)can measure the atmospheric parameters by active remote sensing,so it plays an increasingly important role in the fields of atmospheric science research,environmental monitoring,weather forecasting and so on.The atmospheric density decreases exponentially with altitude,and the atmospheric density at high altitude is far lower than that at low altitude.Subject to that,the detection for upper atmosphere is of difficulty and the detection data is insufficient.With the development of lidar technology in recent years,the detection ability of lidar to measure air density,temperature,wind field and other parameters of upper atmosphere has been gradually improved,and it has been applied to the development of mesospheric model and near space environment monitoring.The detection mechanism of lidar for upper atmosphere,as well as the detection capability and station construction of lidar in China is introduced systematically,and the development trend of lidar is also briefly prospected.
