摘要:子午工程海南富克站甚高频(very high frequencyVHF)相干散射雷达位于我国海南省儋州市富克镇(109.1\(°\)E,19.5\(°\)N),隶属于中国科学院国家空间科学中心。雷达波束正交于电离层E和F层磁力线,其回波主要来自沿磁力线排列的电离层场向不规则体的后向散射。20142019年甚高频相干散射雷达连续不间断地对海南地区电离层E层至F层高度范围内的等离子体不规则体进行探测,从原始探测数据同相、正交相(I、Q)信号中实时计算出回波强度并上传至子午工程数据中心网站。通过这一数据可以得到我国低纬地区(海南)电离层场向不规则体发生率随太阳活动、季节和地方时的变化,以及电离层不规则体发生情况的逐日变化和暴时响应特征。本数据集能够为我国电离层物理领域内相关的研究、工程项目、空间天气预报提供数据支撑。

Abstract & Keywords
Abstract: The Very High Frequency (VHF) coherent scatter radar of Meridian Project locates in Fuke, Hainan island of China (109.1°E, 19.5°N), and belongs to National Space Science Center, Chinese Academy of Sciences. The radar beams are set to be perpendicular to the magnetic field lines in ionospheric E- and F-layers in order to obtain the backscattered echoes from ionospheric field-aligned irregularities. The VHF coherent scatter radar continuously detected the plasma irregularities in E- and F-region from 2014 to 2019, and the real-time echo intensity calculated from I/Q signals is uploaded to Meridian Project Data Center. Through this dataset, the dependences of ionospheric irregularities occurrence on solar activity, seasons and local time in low-latitude region (Hainan) can be derived, as well as the day-to-day variations and response characteristics during geomagnetic storms of irregularities. The dataset will provide support for related research and projects on space environment, as well as space weather forecast.
Keywords: coherent scatter radar; low-latitude ionosphere; field-aligned irregularities; quasi-period echoes; spread F; data sharing
