摘要
中间层顶区域大气温度和风场是研究中高层大气动力学的重要参量.简要介绍中国科学技术大学钠测温测风激光雷达系统.其可用于高分辨率探测中间层顶区域(80~105 km)大气温度和风场.给出了该激光雷达测量大气温度和风场的基本原理,对系统的发射部分、接收部分和光电探测采集及时序控制部分进行简要介绍,给出了该系统探测的大气温度和风场的结果.温度和风场结果分别与TIMED/SABER卫星仪器和武汉地基流星雷达观测结果进行了对比.
The middle and upper atmosphere temperature and wind fields are important parameters to study atmospheric dynamics.A sodium temperature/wind lidar system of University of Science and Technology of China(USTC),which can be used for the temperature and wind measurement with high resolution in the mesopause region(80~105 km) is presented briefly.Theory for measuring atmospheric temperature and wind of the lidar is discussed.The transmitter,receiver,photoelectric detecting subsystem,acquisition subsystem and timing control subsystem are described respectively.Finally,the temperature and wind results are given,while the temperature profile observed by sodium lidar is compared with SABER observed,the wind observed by sodium lidar is compared with ground-based meteor radar observed in Wuhan.
