On the Results of a Special Experiment on the Registration of Traveling Ionospheric Disturbances by a System of Synchronously Operating Chirp Ionosondes

open access: yesAtmosphere, 2022
We present the results of observations of traveling ionospheric disturbances (TIDs) based on the data of the operation of the network of chirp oblique sounding stations of the ionosphere on 18–19 December 2019. For observations, four stations of the same

Dataset of Quiet Space Weather Periods for Ionospheric Studies

open access: yesEarth and Space Science, Volume 13, Issue 4, April 2026.
Abstract The ionosphere is a dynamic environment regularly affected from above and from below. This study identifies periods within the years 2000–2023 when the impact from above, driven by space weather, was minimal. The quiet space weather periods have wide usage for two types of ionospheric studies. At first, studies of isolated space weather events

Ionospheric Response to the 8 April 2024 Total Solar Eclipse: Plasma Depletion and Eclipse‐Driven MsTIDs

open access: yesSpace Weather, Volume 24, Issue 4, April 2026.
Abstract The total solar eclipse on 8 April 2024 provided a unique opportunity to investigate the three‐dimensional (3‐D) ionospheric response under enhanced solar activity over North America. In this study, we processed high‐density GNSS observations from ∼1,700 stations to derive vertical total electron content and applied a multi‐term sinusoidal ...

Ionospheric Disturbances in GNSS TEC Data: SpaceX Falcon 9 Deorbit Maneuvers Over CONUS in April–May 2024

open access: yesGeophysical Research Letters
Traveling ionospheric disturbances (TIDs) driven by a large number of internal and external sources are detectable with dense networks of ground‐based Global Navigation Satellite System (GNSS) receivers' measurements of total electron content (TEC).

Unraveling Super Equatorial Plasma Bubbles (EPBs) Evolution During the 23 April 2023 Storm: Multi‐Instrument Observations and GITM‐SAMI3 Simulation

open access: yesSpace Weather, Volume 24, Issue 4, April 2026.
Abstract Storm‐time equatorial plasma bubble (EPB) dynamics play a critical role in space weather impacts on communication and navigation systems, yet the mechanisms governing their formation and evolution under storm conditions remain poorly understood.

Global Impacts of Ultra‐Low‐Frequency Waves: 1. Thermospheric Responses and Traveling Atmospheric Disturbances

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Ultra‐low‐frequency (ULF) waves cause local Thermosphere‐Ionosphere (T‐I) perturbations, but their impacts on the global T‐I system including the generation of Traveling Atmospheric Disturbances (TADs) have never been evaluated. The mechanisms responsible for the TAD generation and propagation, whether through dynamic or thermal process, are ...

Detection and Description of the Different Ionospheric Disturbances that Appeared during the Solar Eclipse of 21 August 2017

open access: yesRemote Sensing, 2018
This work will provide a detailed characterization of the travelling ionospheric disturbances (TIDs) created by the solar eclipse of 21 August 2017, the shadow of which crossed the United States from the Pacific to the Atlantic ocean.

Rapid Evolution of Super Equatorial Plasma Bubbles and X‐Pattern EIA Formation During Extreme Storm Conditions on 12 November 2025

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Extreme conditions during storms profoundly alter the evolution of equatorial plasma bubbles (EPBs), yet the key dynamics remains poorly understood. We document the rapid expansion, contraction, and decay of super EPBs in South America during the 12 November 2025 storm with Interplanetary Magnetic Field (IMF) Bz/By magnitude exceeding ∼50 nT ...

IonKit-NH: A MATLAB-based toolkit for ionospheric detection of earthquake, tsunami and volcanic eruption

open access: yesEarthquake Research Advances
In recent years, GNSS-derived total electron content (TEC) measurements have emerged as an effective method for detecting natural hazards through their ionospheric manifestations.

Enhancing Low‐Latitude Ionospheric Irregularity Prediction With Generalized Linear Models

open access: yesSpace Weather, Volume 24, Issue 3, March 2026.
Abstract The ionosphere poses challenges for accurate forecasting due to its complexity and variability. Irregularities in the lower ionosphere are influenced by local time, season, geographic location, solar activity and space weather, complicating precise predictions.
