有人建议，一些瞬态离子云的起源，通常被认为是负责低水平的零星无线电反射，可能是由于大的宇宙射线阵雨。研究表明，足以产生某些射电反射的级联宇宙射线阵雨确实存在，但没有足够的公开证据来确定是否已经观测到的任何回声实际上是由这种阵雨引起的。更确凿的证据可以从从水平或垂直方向波束观察到的无线电回波的频率大小分布中获得。
It is suggested that the origin of some of the transient ionic clouds, generally assumed to be responsible for the low level sporadic radio reflexions, may be due to large cosmic ray showers. It is shown that cascade cosmic ray showers of sufficient energy to produce some of these radio reflexions certainly exist, but there is insufficient published evidence to decide whether any of the echoes already observed are actually due to such showers. More conclusive evidence could be obtained from the frequency-size distribution of the radio echoes observed from a horizontal or vertically directed beam.
