Abstract:

This report summarizes the results of a study of short term variations of the ionosphere. The digital ionograms used in this analysis were recorded at Brighton, Colorado, many of them at a high rate of 12 ionograms per hour and faster. The results show that oscillations of the electron density distribution take place in the F region with varying amplitudes and with periods of a fraction of an hour. The oscillations are coupled with varying tilts. Rapid changes, mainly of the electron density, are also observed at E-layer heights and many records indicate that the echoes come from tilted sporadic-E patches with relatively small dimensions.
