Propagation of Pi 2 micropulsations through the ionosphere

Journal of Geophysical Research, 1965
Until recently it has been thought that Pi 2 activity was observed simultaneously over the earth's surface [Angenheister, 1912; Grenet et al., 1954]. The first strong evidence that this was not the case was presented by Herron [1964], who observed sizeable phase shifts of the order of seconds between stations separated by hundreds of kilometers along ...
