利用中国区域内五个GPS台站(一个台站处于日全食区域、四个台站处于日偏食区域)观测数据,研究2009年7月22日日全食期间电离层总电子含量(TEC)的变化,结果表明,日全食期间,电离层TEC值经历了下降和恢复的过程,最小TEC相对于最大食偏的时间延迟约为1~10 min;台站测得最小TEC的星下点(IPP)越靠近日全食带TEC下降量越大,在日食期间武汉站(114.35°E,30.53°N)TEC相对于各参考日期的TEC,其平均下降量最大,达到4.58TECU. |

Variations of the ionospheric Total Electron Content(TEC) during the total solar eclipse of July 22,2009 was investigated using GPS observed data obtained at five GPS stations(one is in total solar eclipse region,the others are in partial solar eclipse region) in China region.Results indicate that during the total solar eclipse,TEC experiences a decline and recovery process;the delay of a minimum level of TEC with respect to the maximum phase of the eclipse is about 1~10min;the Ionosphere Pierce Point(IPP) of minimum TEC is closer to total solar eclipse region,the decrease of TEC is larger,and during the total solar eclipse,the mean decay TEC compared to the TEC on reference date above WUHN station(114.35°E,30.53°N) is the maximum,reaching 4.58 TECU. |
