Preliminary analysis of mesospheric summer temperature measurements in Golmud

The mesospheric thermal structure and temperature variations have an important scientific significance in the research of dynamic and thermal process in the middle atmosphere. The middle atmosphere temperature over the Qinghai-Tibet Plateau was measured by the Middle Atmosphere Remote Mobile Observatory in Tibet(MARMOT) lidar, which was designed and built by the Institute of Atmospheric Physics(IAP). The measurement principle, the system configuration, and the specifications of the MARMOT lidar were introduced. The middle atmospheric temperatures in summer at Golmud were analyzed using the lidar data, and the initial results of middle atmospheric temperatures were obtained. By comparing with both the MSIS-00 model data and the TIMED/SABER satellite data, the results showed that the MARMOT lidar results have a good consistency with the MSIS-00 model and the TIMED/SABER satellite results in general. In the upper and lower mesosphere, the temperatures retrieved from lidar are higher than the MSIS-00 model results and the TIMED/SABER satellite results. In the mid-mesosphere, the lidar data and the satellite data are slightly lower than model results.
