【Abstract】 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 niesopause 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.更多还原
