| Abstract | 首次利用廊坊中频雷达和武汉、嘉兴、廊坊等三站GPS对2009年7月22日日全食电离层效应进行了观测，日食期间，中频雷达D层78 km高度上电子密度减小了约67%，电子密度为200 cm~(-3)的高度上升了近10 km，GPS/TEC减小了1 TECU左右，其变化的最大相位与日食最大相位几乎同步；日食后，观测到周期为2个多小时的电离层扰动现象． |
| Other Abstract | For the first time, Langfang Medium-Frequency (MF) radar was used to simultaneously observe the ionospheric effects due to the solar total eclipse on 22 July 2009, with three GPS/TEC receivers operated at Wuhan, Jiaxing and Langfang respectively. Results show that during the solar eclipse, the D layer electron densities at 78km level observed by the MF radar decreased by 67% and the altitude level of equivalent electron densities of 200cm~(-3) uprised about 10km. The ionospheric Total Electron Content (TEC) observed by the GPS/TEC receivers in the above three sites respectively decreased about 1 TECU. Their minimum reductions of the D layer electron densities and TEC are synchronous with the solar eclipse maximum phase. After the solar eclipse, a Traveling Ionospheric Disturbance (TID) was revealed with a period of larger than 2h in the GPS/TEC data. |
