The Lidar Research Laboratory in the University of Science and Technology of China (USTC) supports education and research in the middle and upper atmospheric sciences through a set of lidar systems. Since the year 2004, three ground-based lidars have been developed to observe the different atmospheric parameters from the ground level to 110km:

(1) The Rayleigh-Sodium Lidar has been built up at the end of 2005 and is capable of measuring the middle atmospheric temperature from 30km to 70km and the sodium density in mesopause regin from 80km to 110km.

(2) The Doppler Wind Lidar was established in the year 2009, and is employed for observing the wind field from 3km to near 40km with the double-edge direct wind detection technique.

(3) The Narrow-band Sodium Lidar (under the development) is a High-spectral-resolution lidar, and is aimed at sensing the mesopause region (80km to 110km) temperature and wind field.
