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

Geophysical 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).

Space Weather Disrupts Low‐Latitude Network RTK: Evidence From LSTIDs During June 2025 Geomagnetic Storm

Space Weather, Volume 24, Issue 6, June 2026.
Abstract The geomagnetic storm on 1 June 2025 generated pronounced large‐scale traveling ionospheric disturbances (LSTIDs) over China, captured by dense GNSS networks. It has been unclear whether network real‐time kinematic (NRTK) positioning, which relies on spatial interpolation from multiple reference stations, remains effective under such extreme ...

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.

First Detection of the Two‐Dimensional Vertical Propagation of Traveling Ionospheric Disturbances Associated With Atmospheric Gravity Waves in the Martian Ionosphere

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We report the detection of a traveling ionospheric disturbance (TID) captured by the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) Active Ionospheric Sounding (AIS) instrument aboard the Mars Express spacecraft at 150–250 km altitude.

Statistical study of traveling ionospheric disturbances over South Africa [PDF]

, 2019
This thesis provides a statistical analysis of traveling ionospheric disturbances (TIDs) in South Africa. The velocities of the TIDs were determined from total electron content (TEC) maps using particle image velocimetry (PIV).

Assessment of Ionospheric Model Performance Over the US During the Extreme G5 2024 Mother's Day Geomagnetic Storm

Space Weather, Volume 24, Issue 5, May 2026.
Abstract This study evaluates 17 ionospheric models' performance over the Continental United States (CONUS) during the 2024 Mother's Day geomagnetic storm, using ground‐based GNSS Total Electron Content (TEC) and single‐frequency (SF) precise Single Point Positioning (SPP) technique. The storm produced significant positive storm effects during its main

Daytime Ionospheric Density Enhancement Driven by Poleward Neutral Wind Shear Associated With Gravity Waves During the November 2025 Geomagnetic Storm

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The threefold daytime electron density increases, along with strong poleward meridional winds exceeding 200 m/s were captured by Sanya Incoherent Scatter Radar (SYISR) during the geomagnetic storm of 12 November 2025. The great ionospheric enhancements were extending to mid‐latitudes over 40° observed by total electron content (TEC) from ...
