PREDOMINANT TRAVELING IONOSPHERIC DISTURBANCES OVER EASTERN EUROPE DURING LOW LEVELS OF SOLAR AND GEOMAGNETIC ACTIVITIES USING INCOHERENT SCATTER RADAR DATA [PDF]
Purpose: Detection of wave processes of various temporal and spatial scales in the mid-latitude ionosphere over the Eastern Europe near the characteristic geophysical time periods (equinoxes and solstices) during magnetically quiet and weakly disturbed ...

Using the representative statistics on traveling ionospheric disturbances (TIDs) obtained by Yekaterinburg and Magadan radars, we have shown that distributions of TIDs and average TID velocities by azimuths and local time agree well with the hypothesis ...

Solar wind Alfvén waves: a source of pulsed ionospheric convection and atmospheric gravity waves [PDF]
A case study of medium-scale travelling ionospheric disturbances (TIDs) that are correlated with solar wind Alfvén waves is presented. The HF radar ground-scatter signatures of TIDs caused by atmospheric gravity waves with periods of 20-40min are

We used dense global navigation satellite system data from China to track the propagation of traveling ionospheric disturbances (TIDs) triggered by the 2022 January 15 Tonga volcanic eruption. We identified two TIDs originating from the eruption.

Earthquakes are known to generate disturbances in the ionosphere. Such disturbances, referred to as co-seismic ionospheric disturbances, or ionoquakes, were previously reported for large earthquakes with magnitudes Mw≥ 6.6.

Some characteristics of large-scale travelling ionospheric disturbances and a relationship between the F2 layer height rises of these disturbances and equatorial pre-sunrise events [PDF]
Initially some characteristics of large-scale travelling ionospheric disturbances (LS-TIDs) have been discussed briefly particularly as reported in the early literature.

Traveling ionospheric disturbances (TIDs) were observed over Japan by using Global Navigation Satellite System (GNSS) receiver network data after the eruption of Hunga Tonga-Hunga Ha’apai in Tonga on 15 January 2022.

Traveling ionospheric disturbances triggered by the 2009 North Korean underground nuclear explosion [PDF]
Underground nuclear explosions (UNEs) can induce acoustic-gravity waves, which disturb the ionosphere and initiate traveling ionospheric disturbances (TIDs).

Traveling Ionospheric Disturbances (TIDs) are wave-like propagating irregularities that alter the electron density environment and play an important role spreading radio signals propagating through the ionosphere. A method combining spectral analysis and

Simulation of Focusing Effect of Traveling Ionospheric Disturbances on Meter-Decameter Solar Dynamic Spectra [PDF]
For the first time we present simulation results of the focusing effect of the ionospheric plasma density irregularities, namely, Medium Scale Traveling Ionospheric Disturbances (MSTIDs), on solar radio emission by applying a ray-tracing method to the ...
