The bahaviour of ionospheric drift during a superstorm in November 2004
Kouba, Daniel
This article presents results obtained by processing the measurement drift in the F layer of the ionosphere from the Pruhonice observatory.Diurnal and seasonal behaviour of the ionosphere is examined. The effect of strong geomagnetic storms on the ionosphere is presented.
Acoustic-gravity, tidal, and planetary waves in the ionosphere
Koucká Knížová, Petra ; Mošna, Zbyšek ; Potužníková, Kateřina
Neutral atmosphere affects strongly the ionosphere. We study influence of the neutral wave activity on the ionosphere in range of periods from minutes to days (acoustic waves to planetary waves).
