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), 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 sodium lidar observed temperature profile is compared with SABER observed and the sodium lidar observed wind is compared with ground-based meteor radar observed in Wuhan.

Key words: middle and upper atmosphere, atmospheric temperature, wind fields, sodium temperature/wind lidar
