摘要:

本文给出了电离层对微弱和明亮的太阳耀斑响应的分析结果。这项分析使用了作者开发的全球探测太阳耀斑对电离层影响的技术,其基础是利用国际全球定位系统网络对电离层总电子含量进行相位测量。该方法的实质是,使用适当的滤波和对TEC的变化进行相干处理,TEC是从GPS数据中确定的,同时用于分析中使用的所有台站的整套可见GPS卫星。这种技术是有用的,用于确定电离层响应微弱的太阳耀斑(X射线C类)时,TEC响应的变化幅度,以单独的线上的视线到GPS卫星是可比的背景波动的水平。研究了耀斑在太阳上的位置对TEC变化响应幅度的影响。

英文摘要:

Results derived from analysing the ionosphere response to faint and bright solar flares are presented. The analysis used technology of a global detection of ionospheric effects from solar flares as developed by the authors, on the basis of phase measurements of the total electron content (TEC) in the ionosphere using an international GPS network. The essence of the method is that use is made of appropriate filtering and a coherent processing of variations in the TEC which is determined from GPS data, simultaneously for the entire set of visible GPS satellites at all stations used in the analysis. This technique is useful for identifying the ionospheric response to faint solar flares (of X-ray class C) when the variation amplitude of the TEC response to separate line-on-sight to GPS satellite is comparable to the level of background fluctuations. The dependence of the TEC variation response amplitude on the flares location on the Sun is investigated.
