摘要:大气水平风场是研究大气动力特征、过程以及大气上下层之间的动力耦合的重要参数。MST(Mesosphere Stratosphere and Troposphere)雷达在大气风场探测中发挥独特的作用,可获取高时空分辨率的大气风场廓线数据。在国家重大科技基础设施项目子午工程支持下由中国科学院大气物理研究所主持建设的北京MST雷达位于华北香河全大气层野外科学观测研究站(39.75°N116.96°E)。本数据集包含2012年北京MST雷达中模式探测的大气水平风速、水平风向数据。探测高度范围覆盖325 km,垂直分辨率600米,探测时间间隔为30分钟。去除异常点后的风场廓线与探空数据有很好的一致性。本数据集可在气象、空间环境、航天保障等研究与应用领域发挥重要作用。

Abstract & Keywords
Abstract: The atmospheric horizontal wind is an essential parameter for studying atmospheric dynamic characteristics, processes, and dynamic coupling between the upper and lower atmosphere. MST (Mesosphere Stratosphere and Troposphere) radar plays a unique role in atmospheric wind field detection and can obtain horizontal wind profiles with high temporal and spatial resolution. The Beijing MST radar, which was built and operated by the Institute of Atmospheric Physics, Chinese Academy of Sciences under the support of the Chinese Meridian Project. It is located at Xianghe Observatory of Whole Atmosphere, Institute of Atmospheric Physics, Chinese Academy of Sciences (39.75°N, 116.96°E). This dataset contains the atmospheric horizontal wind speed and direction observed by the Beijing MST radar in 2012 operated on middle mode. The detection height range cover 3 to 25 km, the vertical resolution is 600 m, and the sampling interval is 30 minutes. After removing the abnormal points, the horizontal wind profile is in good agreement with the nearest Beijing radiosonde data. This dataset can play an important role in research and application fields such as meteorology, space environment, and aerospace support.
Keywords: Beijing MST radar; horizontal wind speed; horizontal wind direction; troposphere and lower stratosphere; Xianghe station
