Influence of the terrestrial environment on the temporal and statistical characteristics of Jovian decametric radiation

The characteristics of Jovian decametric pulses are compared with satellite and radio star scintillations known to arise in the terrestrial ionosphere. The diurnal, seasonal, and altitude variations of the scintillation phenomena appear to be absent in the planetary signals, suggesting that the local ionosphere is not the source of the Jovian pulse structure. On the other hand, the ionosphere exerts a marked influence on the probability of reception, and to a lesser extent on the intensity, of the Jovian decametric signals.
