An investigation of traveling ionospheric disturbances (TIDs) in the SANAE HF radar data

, 2022
This thesis aims to study the characteristics of traveling ionospheric disturbances (TIDs) as identified in the radar data of the South African National Antarctic Expedition (SANAE) Super Dual Auroral Radar Network (SuperDARN) radar located in Antarctica.

GPS network observation of traveling ionospheric disturbances following the Chelyabinsk meteorite blast [PDF]

Annales Geophysicae, 2016
We use the Global Positioning System (GPS) network in northwest China and central Asia to monitor traveling ionospheric disturbances (TIDs), which were possibly excited by the large meteorite blast over Chelyabinsk, Russia, on 15 February 2013.

N-dimensional Lomb Scargle Periodogram analysis of traveling ionospheric disturbances using ionosonde data [PDF]

Frontiers in Astronomy and Space Sciences
There is a multitude of wave-like phenomena in Earth’s ionosphere and thermosphere such as acoustic waves, gravity waves, planetary waves, tides, and Traveling Ionospheric Disturbances (TIDs) which are the ionospheric manifestation of atmospheric waves ...

Multiwave Structure of Traveling Ionospheric Disturbances Excited by the Tonga Volcanic Eruptions Observed by a Dense GNSS Network in China

Space Weather, 2023
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.

Identification of potential precursors for the occurrence of Large-Scale Traveling Ionospheric Disturbances in a case study during September 2017 [PDF]

Journal of Space Weather and Space Climate, 2020
Traveling Ionospheric Disturbances (TIDs) reflect changes in the ionospheric electron density which are caused by atmospheric gravity waves. These changes in the electron density impact the functionality of different applications such as precise ...

Observations of traveling ionospheric disturbances driven by gravity waves from sources in the upper and lower atmosphere [PDF]

Annales Geophysicae
The observed traveling ionospheric disturbances (TIDs) are attributed to atmospheric gravity waves generated by auroral sources in the lower thermosphere or gravity waves generated in the troposphere by midlatitude weather systems.

Global Observational Comparison of Large‐Scale Traveling Atmospheric and Ionospheric Disturbances During the May 2024 Geomagnetic Storm

Geophysical Research Letters
During the geomagnetic storm on 10 May 2024, neutral density measurements from 14 Tianmu, Swarm, and GRACE‐FO satellites at ∼510 km altitude, combined with total electron content (TEC) observations, enabled the first global observational comparison of ...

Three‐Dimensional Reconstruction of Ionospheric Disturbances Using Tikhonov Regularization After 2022 Tonga Volcanic Eruption

Earth and Space Science
Following significant natural hazards, traveling ionospheric disturbances (TIDs) are generated that affect the ionosphere. Understanding the three‐dimensional structure of these TIDs is crucial for understanding their propagation mechanisms.

Study on Ionospheric Depletion and Traveling Ionospheric Disturbances Induced by Rocket Launches Using Multi-Source GNSS Observations and the MRMIT Method

Remote Sensing
Rocket launches constitute a major anthropogenic source of disturbance in the near-Earth space environment, inducing significant ionospheric perturbations through both chemical and dynamic mechanisms.
