摘　　要：中层顶区域存在着大量的金属原子和离子,这些金属原子和离子可作为示踪剂去研究中层顶区域的动力学和化学过程。激光雷达是探测金属原子离子的最有利工具。激光雷达数据集对于研究中层顶大气金属层以及电离层和中高层大气的耦合具有重要意义。激光雷达数据集根据子午工程一期北京、武汉、合肥和海口台站的钠激光雷达和瑞利激光雷达探测得到的回波光子获得。本数据集包括30-80 km的瑞利散射光子计数以及反演出的中层大气密度和温度数据、80-110 km的荧光散射光子计数和钠密度数据。通过对本数据集的分析可以得到金属钠密度对低层大气中重力波、潮汐波的响应,金属钠层的长期和短期变化、突发钠层与突发E层之间的关系以及中层大气的密度和温度变化。本数据集为空间物理学研究提供了更多的数据保障。There are many metal atoms and ions in the mesopause region. These metal atoms can be used as tracers to study the dynamical and chemical processes in this region. Lidar is the most powerful tool for detecting metal atoms and ions. The lidar dataset is of great significance for studying the metal layer in the mesopause region and the coupling between the ionosphere and the middle and upper atmosphere. The lidar dataset is obtained from echo photons detected by sodium lidar and Rayleigh lidar at Meridian Project stations in Beijing, Wuhan, Hefei and Haikou. The dataset includes Rayleigh scattered photon counts from 30 to 80 km, inverse atmosphere density, temperature data, fluorescence scattered photon counts from 80 to 110 km and sodium density data. Through the analysis of the dataset, we can get the response of the metal sodium density to gravity waves and tidal waves in the lower atmosphere, the long-term and short-term variations of the metal sodium layer, the relationship between the sporadic sodium layer and the sporadic E layer;and the density and temperature changes of the middle atmosphere. This dataset also provides more support for the research of space physics.
