电离层对2001年6月21日日全食的响应
Ionospheric response to the total solar eclipse of June 21, 2001
摘要：
讨论了2001年6月21日日全食期间电离层响应的主要参数的测量结果。这项研究的基础上使用的数据，从三个站的全球定位系统网络位于非洲的全食带的地区。这一时期的特点是地磁扰动水平较低（Dst指数从-6到22 nT不等），这大大缓解了探测电离层对日食反应的问题。一项分析表明，所有全球定位系统台站的总电子含量都明显减少（降低）。TEC的最小值之间的延迟相对于日食全食是9-37分钟。TEC的抑郁症的深度和持续时间分别为0.5-0.9 TECU和30-67分钟，分别。在这项研究中获得的结果与早期的测量和理论估计是一致的。
英文摘要：
We discuss the measurements of the main parameters of the ionospheric response to the total solar eclipse of June 21, 2001. This study is based on using the data from three stations of the global GPS network located in the area of the totality band in Africa. This period was characterized by a low level of geomagnetic disturbance (the Dst-index varied from -6 to 22 nT), which alleviated greatly the problem of detecting the ionospheric response to eclipse. An analysis revealed a clearly pronounced effect of a decrease (depression) of the total electron content (TEC) for all GPS stations. The delay between the smallest value of the TEC with respect to eclipse totality was 9-37 min. The depth and duration of the TEC depression were 0.5-0.9 TECU and 30-67 min, respectively. The results obtained in this study are in good agreement with earlier measurements and theoretical estimations.
