| Zusammenfassung |
| The present study concerns variability of the wave activity in the sporadic E layer plasma. Within oscilations in height (hEs) and critical frequency (foEs) of sporadic E layer together with the temperature in the lower laying neutral atmosphere we search for the wave-like oscilations over a wide period range of hours to several days, covering tidal and planetary oscillation domain. In order to detect modulation of the E layer plasma wave-like oscillation by planetary waves from lower laying atmosphere we analyse oscillation in the neutral atmosphere temperature at the level of 10hPa. By means of the wavelet transform we detect wave occurence and its persistence. Using data from special summer high sampling rate campaigns of ionospheric vertical sampling performed since 2004 we evaluate the inter annual variability. |
