A Method for Determining Parameters of Mid-Scale Traveling Ionospheric Disturbances [PDF]

Sensors
The growing amount of available experimental data on the Earth’s ionosphere total electron content measurements requires the development of modern data processing instruments. Traveling ionospheric disturbances (TIDs) are one of the ionospheric phenomena

Understanding Inter-Hemispheric Traveling Ionospheric Disturbances and Their Mechanisms

Remote Sensing, 2020
Traveling ionospheric disturbances (TIDs) are wave-like disturbances in ionospheric plasma density. They are often observed during both quiet (medium-scale TID) and geomagnetically disturbed (large-scale TID) conditions. Their amplitudes can reach double-

The Observation of Traveling Ionospheric Disturbances Using the Sanya Incoherent Scatter Radar

Remote Sensing
In this study, we used the Sanya Incoherent Scatter Radar (SYISR) to observe the altitude profiles of traveling ionospheric disturbances (TIDs) during a moderate magnetic storm from 13 to 15 March 2022. Three TIDs were recorded, including two large-scale

Traveling ionospheric disturbances triggered by the 2009 North Korean underground nuclear explosion [PDF]

Annales Geophysicae, 2015
Underground nuclear explosions (UNEs) can induce acoustic-gravity waves, which disturb the ionosphere and initiate traveling ionospheric disturbances (TIDs).

Multi-instrument observations of polar cap patches and traveling ionospheric disturbances generated by solar wind Alfvén waves coupling to the dayside magnetosphere [PDF]

Annales Geophysicae, 2022
During minor to moderate geomagnetic storms, caused by corotating interaction regions (CIRs) at the leading edge of high-speed streams (HSSs), solar wind Alfvén waves modulated the magnetic reconnection at the dayside magnetopause.

Ionospheric Disturbances Observed Following the Ridgecrest Earthquake of 4 July 2019 in California, USA

Remote Sensing, 2022
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.

Identification of Large-Scale Travelling Ionospheric Disturbances (LSTIDs) Based on Digisonde Observations

Atmosphere, 2023
In this paper we analyze Digisonde observations obtained in the European region to specify the effects of large-scale travelling ionospheric disturbances (LSTIDs) on the ionospheric characteristics that define the conditions in the bottomside ionosphere.

The Persistent Ionospheric Responses Over Japan After the Impact of the 2011 Tohoku Earthquake

Space Weather, 2020
In this study, we report the persistent impacts of the 2011 Tohoku earthquake/tsunami on the ionosphere using the ground‐based Global Navigation Satellite System and FORMOSAT‐3/COSMIC total electron content.

A method for real-time identification and tracking of traveling ionospheric disturbances using ionosonde data: first results

Journal of Space Weather and Space Climate, 2020
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

ADDTID: An Alternative Tool for Studying Earthquake/Tsunami Signatures in the Ionosphere. Case of the 2011 Tohoku Earthquake

Remote Sensing, 2019
In this work, we characterized the ionospheric disturbances generated during the Japan Tohoku earthquake of 11 March 2011, by means of the Atomic Decomposition Detector of Traveling Ionospheric Disturbances (ADDTID) algorithm.
