Abstract

The results of are presented of determining the height profiles of electron concentration \(N(h)\) during the daytime solstice of June 19–30, 2015. Dependences of \(N(h)\) recorded in a calm state and the presence of sporadic structures of varying intensity are given. The histograms of the distribution of the variable plasma concentration for four values of the height of the lower ionosphere were determined. It is shown that, at an altitude of 100 km, an increase in the electron concentration by a factor of 4–5 occurs under the action of an X-ray flare from the Sun. Manifestations of different types of sporadic formations in changes in the amplitude of radio signals are considered and three types of amplitude variations characteristic of sporadic structures are identified.

摘要

被呈现确定电子浓度的高度轮廓的结果\（N（H）\） 6月19日至30日，2015年的依赖性的白天期间冬至\（N（H）\）记录在平静状态和给出了强度变化的零星结构的存在。确定下部电离层高度的四个值的可变血浆浓度分布的直方图。结果表明，在100 km的高度上，在来自太阳的X射线耀斑的作用下，电子浓度增加了4-5倍。考虑了无线电信号幅度变化中不同类型的零星形成的表现，并确定了零星结构特征的三种类型的幅度变化。
