Tomographic Imaging of Traveling Ionospheric Disturbances Using GNSS and Geostationary Satellite Observations [PDF]

, 2020
Traveling ionospheric disturbances (TIDs) are the manifestations of atmospheric gravity waves in the ionosphere. These disturbances have practical importance because they affect satellite navigation technologies such as Global Navigational Satellite ...

Ionospheric tilt measurements: application to traveling ionospheric disturbances climatology study

, 2020
Ionospheric tilt is a concept used to characterize local horizontal electron density gradients in the ionosphere using a mirror reflection model. Experimental results are presented that illustrate the validity and accuracy of such approach.

Ionospheric disturbances observed over Japan following the eruption of Hunga Tonga-Hunga Ha’apai on 15 January 2022

Earth, Planets and Space, 2022
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.

Statistical relation of traveling ionospheric disturbances with neutral wind and disturbances in the stratosphere

Solar-Terrestrial Physics, 2022
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 ...

The Impacts of Tropospheric Gravity Wave‐Generated MSTIDs on Skywaves at Mid‐latitude North American Sector Observed and Modeled Using SuperDARN HF Radars

Radio Science, Volume 61, Issue 9, September 2026.
Abstract Trans‐ionospheric high frequency (HF: 3–30 MHz) response to atmospheric gravity waves (GWs) is studied in the middle‐latitude ionosphere in relation to thunderstorm activity. SuperDARN HF radar observations are compared against the model simulations to quantify the impact of GW‐generated medium‐scale traveling ionospheric disturbances (MSTID ...

Properties of traveling ionospheric disturbances (TIDs) over the Western Cape, South Africa [PDF]

, 2015
Travelling Ionospheric Disturbances (TIDs) are said to be produced by atmospheric gravitational waves propagating through the neutral ionosphere. These are smaller in amplitude and period when compared to most ionospheric disturbances and hence more ...

Probing of medium-scale traveling ionospheric disturbances using HF-induced scatter targets [PDF]

, 2006
International audienceExperimental results from the Tromsø and Sura heating experiments at high and mid-latitudes are examined. It is shown that the combination of HF-induced target and bi-static HF Doppler radio scatter observations is a profitable ...

2022 Tonga Volcanic Eruption Induced Global Propagation of Ionospheric Disturbances via Lamb Waves

Frontiers in Astronomy and Space Sciences, 2022
The Tonga volcano eruption at 04:14:45 UT on 2022-01-15 released enormous amounts of energy into the atmosphere, triggering very significant geophysical variations not only in the immediate proximity of the epicenter but also globally across the whole ...

Ionospheric disturbances over South America related to Tonga volcanic eruption

Earth, Planets and Space, 2023
On January 15, 2022, we observed various unusual atmospheric wave events over South America: Atmospheric pressure waves (Lamb mode) around 12:30 to 17:30 UT, tsunamis along the Chilean coast at around 17:00 to 19:00 UT, and ionospheric disturbances ...

Longitudinal Variation of Ionospheric Irregularities and Response of the Ionosphere During 10–13 May and 10–13 October 2024 Geomagnetic Storms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We examine the response of the ionosphere to the 10–13 May 2024 and 10–13 October 2024 geomagnetic storms, the two recent great geomagnetic storms of solar cycle 25. We identified the occurrence of ionospheric irregularities during the two geomagnetic storms.
