Traveling Ionospheric Disturbances Observed Over South America After Lithospheric Events: 2010–2020

open access: yes, 2022
Here, the ionospheric response to earthquakes, earthquakes inducing tsunamis, and volcanic eruptions are presented as a contribution to the so‐called ionospheric seismology with the eventual development of real‐time warning systems in mind.

Auroral Effect on Mid‐Latitude Ionospheric Disturbances Over Europe During the Extreme Geomagnetic Storm of 10 May 2024

open access: yesSpace Weather, Volume 24, Issue 8, August 2026.
Abstract Large ionospheric disturbances were observed over Europe during the extreme geomagnetic storm on 10 May 2024. This study analyzes GNSS‐derived total electron content (TEC) and all‐sky imager data to investigate these disturbances. Pronounced TEC enhancements, irregularities, and strong gradients were confined to the auroral region above the ...

Direct Observations of Large‐Scale Wave Structure and Post‐Sunset Rise of the Ionosphere in the Generation of Equatorial Spread F

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Large‐scale wave structure (LSWS) and the post‐sunset rise (PSSR) are two key factors in the generation of equatorial spread F (ESF). In this study, we reported continuous and direct observations of LSWS and PSSR and their effects on seeding ESF by Sanya incoherent scatter radar (SYISR) and ionosonde in September–October 2024.

On the dynamics of large-scale traveling ionospheric disturbances over Europe on 20 November 2003 [PDF]

open access: yes, 2017
Ionospheric disturbances, often associated with geomagnetic storms, may cause threats to radio systems used for communication and navigation. One example is the super storm on 20 November 2003, when plenty of strong and unusual perturbations were ...

Direct Connection Between Auroral Oval Streamers/Flow Channels and Equatorward Traveling Ionospheric Disturbances

open access: yesFrontiers in Astronomy and Space Sciences, 2021
We use simultaneous auroral imaging, radar flows, and total electron content (TEC) measurements over Alaska to examine whether there is a direct connection of large-scale traveling ionospheric disturbances (LSTIDs) to auroral streamers and associated ...

Occurrence and Characteristics of Traveling Ionospheric Disturbances in the Antarctic Peninsula Region

open access: yes, 2022
A statistical picture of the occurrence and characteristics of Traveling Ionospheric Disturbances (TIDs) over the Antarctic Peninsula is established using Global Navigation Satellite System Total Electron Content and High Frequency sounding observations.

Uplift of the ionosphere by tropospheric and thermospheric Lamb waves induced by the 2022 Tonga volcanic eruption

open access: yesGeoscience Letters
On 15 January 2022, the Tonga submarine volcano eruption generated atmospheric shocks, air pressure perturbations, tsunamis, etc., inducing traveling atmospheric disturbances (TADs) and traveling ionospheric disturbances (TIDs).

High Latitude Thermosphere and Ionosphere Density Response to the May 2024 Geomagnetic Storm Observed by the LLITED CubeSat Mission

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The May 2024 G5 geomagnetic storm produced significant disturbances in the ionosphere and thermosphere, particularly at high latitudes. Using high‐resolution in situ ion and neutral density measurements from the NASA Low‐Latitude Ionosphere/Thermosphere Enhancements in Density (LLITED) CubeSat at 430 km altitude, this study documents notable ...

Revisiting the Ionospheric Disturbances Over Low Latitude Region of China During Super Typhoon Hato

open access: yesSpace Weather
The ionosphere exhibits complex variations due to the influences from above and below. To distinguish the source of ionospheric disturbances is important for understanding the variation process and the coupling mechanism among different regions.

Large‐Scale Traveling Ionospheric Disturbances Over the Asian‐Pacific Sector During 10–11 May 2024 Geomagnetic Superstorm: Ionosonde Observation and MAGE Simulation

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The large‐scale traveling ionospheric disturbances (LSTIDs) over the Asian‐Pacific sector during the 10–11 May 2024 superstorm are investigated using ionosonde observation and simulation from a whole geospace model—Multiscale Atmosphere Geospace Environment (MAGE), which fully couples multiple magnetosphere, ionosphere and thermosphere models.
