Design and implementation of ionospheric multi-parameter anomaly monitoring system in Sichuan-Yunnan region

  • 摘要: 本文介绍了川滇地区电离层多参量异常监测系统的设计思路与功能实现,并将系统应用于2019年6月17日四川长宁MS6.0地震的监测试验。结果表明:该系统实现了全球和中国区域垂直总电子含量VTEC、站点VTEC和F2层临界频率foF2异常变化的实时监测,有助于开展示范性地震电离层异常监测工作,其图形及数据结果可为地震-电离层异常扰动判识提供佐证,为川滇地区地震监测预报提供电离层前兆信息支持。
