Abstract

With the development of laser and photoelectric technology, narrowband sodium (Na) Doppler lidars which can measure temperature and wind in the mesosphere and lower thermosphere (MLT) region were established in several observation sites in China. In this paper, the observation of temperature and wind in both nighttime and daytime by a Na lidar recently established in Lanzhou, China (35.95°N, 104.13°E) was reported. The multichannel data acquisition system based on MCS8 was introduced, and the preliminary observational results obtained on January 2022 was presented. The temperature profile measured by lidar was compared with the result from satellite, showing basically consistent trend between 80 and 110 km.
