一次中纬度扩展F事件中电离层行波扰动的研究
Investigation of Traveling Ionospheric Disturbances during a Midlatitude Spread F Event
摘要：
在中纬度扩展F（MSF）事件期间，收集数据以调查可能导致MSF的情况。利用NCAT-SCINDA GPS站和CORS站的电子总含量（TEC）资料，分析了MSF期间美国弗吉尼亚州沃洛普斯岛上空的电离层行波扰动（TID）。除了TEC分析之外，还使用NCAT-SCINDA全球定位系统接收器、USRP接收器和窄带接收器进行了闪烁计算。在整个MSF期间，GPS、USRP和NB信号的闪烁水平非常低。多个CORS站点的TEC数据分析表明，在MSF事件区域内存在向低纬度传播的中等尺度大气重力波（AGW），并具有较小的东向分量。这是一致的理论表明，AGW可能会导致MSF，如果一个相反方向的中性风存在。这项研究是结合探空火箭实验进行的，该实验调查了多种尺度的电离层扰动。
英文摘要：
During a midlatitude spread F (MSF) event, data was collected to investigate the circumstances that may lead to MSF. Using the Total Electron Content (TEC) derived from the NCAT-SCINDA GPS station and the Continuous Operating Reference Stations (CORS) Traveling Ionospheric Disturbances (TID) were analyzed during a period of MSF over Wallops Island, Virginia. In addition to the TEC analysis, scintillation calculations have been made using the NCAT-SCINDA GPS receiver, USRP receiver and a Narrow Band (NB) receiver. Scintillation levels on the GPS, USRP and NB signals were very low throughout the period of MSF. Analysis of TEC data from multiple CORS sites has shown the presence of medium scale atmospheric gravity waves (AGW) within the MSF event region propagating towards low latitudes with a small eastward component. This is consistent with theories showing AGW may lead to MSF if an oppositely directed neutral wind is present. This study was performed in conjunction with a sounding rocket experiment investigating ionospheric disturbances at multiple scale sizes.
