中间层大气温度及时空演变特征对研究青藏高原中高层大气动力、热力学结构具有重要的科学意义。利用大气物理研究所设计建造的MARMOT激光雷达对青藏高原地区中层大气温度进行探测。介绍了MARMOT激光雷达的瑞利测温原理、系统构成及主要功能参数;并利用格尔木夏季大气温度的激光雷达探测资料分析该地区中间层大气温度,并与MSIS-00大气模式和SABER卫星数据进行对比分析,获得了夏季格尔木地区中间层大气温度的初步结果,并对激光雷达的温度数据进行验证。结果表明:MARMOT激光雷达探测温度与MSIS-00模式和SABER卫星结果整体上均具有较好的一致性;在上中间层和低中间层,激光雷达均比MSIS-00模式值、SABER卫星数据偏高;在中中间层,激光雷达与卫星数据均略低于模式值。
The characteristics of atmospheric temperature and temporal-spatial evolution of the middle layer are of important scientific significance for the study of the atmospheric dynamics and thermodynamic structure of the middle and high levels of the Tibetan Plateau. Based on the MARMOT lidar designed and constructed by Institute of Atmospheric Physics, the mid-atmospheric temperature in the Qinghai-Tibet Plateau is detected. The Rayleigh temperature measurement principle, system configuration and main function parameters of MARMOT laser radar are introduced. The atmospheric temperature of middle layer in the area is analyzed by using the data of Golmud summer atmospheric temperature by lidar, and compared with MSIS-00 atmospheric model and SABER satellite data By comparison, the preliminary results of summer atmospheric temperature in Golmud region were obtained, and the temperature data of laser radar were verified. The results show that the detection temperature of MARMOT lidar is in good agreement with that of the MSIS-00 and SABER satellites. In both the upper and lower middle layers, the lidar is better than the MSIS-00 mode and SABER satellite data High; in the middle layer, lidar and satellite data are slightly lower than the mode value.
