2018-2022年潮汐风场数据集

中国科学院地质与地球物理研究所沿东经120度布置了一条流星雷达子午链,可以有效监测临近空间的大气水平风场。该链横跨我国南北,覆盖北半球中低纬地区,包含漠河、北京、武汉和三亚/乐东四个台站,是国际上第一条大气风场观测链。该子午链可观测MLT区域（70-110 km）的大气风场,时间、高度分辨率为 2 km×1 hr。在此基础上进行建模拟合,获得完整时间和空间覆盖的风场数据

The Institute of Geology and Geophysics, Chinese Academy of Sciences has established a meteor radar meridian chain along 120°E, which can effectively monitor atmospheric horizontal wind fields in the near-space. This chain spans north-south across China, covering the mid-low latitudinal regions of the Northern Hemisphere, and comprises four stations: Mohe, Beijing, Wuhan, and Sanya/Ledong. It is the world’s first atmospheric wind field observation chain. This meridian chain can observe atmospheric wind fields in the MLT region (70–110 km), with a resolution of 2 km × 1 hr (spatial and temporal). Based on the observational data, model fitting is conducted to obtain wind field datasets with complete temporal and spatial coverage.
