| 摘 要： | 21世纪最长的一次日全食于2009-07-22发生,从亚洲东部一直延伸到太平洋地区,同时,日食后期开始伴随着一次中等强度的磁暴。本文利用COSMIC掩星GPS数据反演了食甚时刻电子密度变化情况,利用武汉CORS地基GPS数据反演了局部TEC时序变化情况,并分析了日食电离层效应的物理机制。

| Abstract: | A total solar eclipse on 22 July 2009,the longest one of this century,occurred in East Asia and Pacific.Meanwhile,a medium magnetic storm arise in the late eclipse.The electron density profiles in maximum eclipse time were obtained from COSMIC radio occultation,and time series of TEC in local area was obtained from ground GPS stations of Wuhan CORS.And some physical mechanism of ionospheric effects during in the eclipse were analyzed. |
