Fast Computerized Ionospheric Tomography Using GNSS‐TEC in Densely Observed Regions

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract In recent years, the range of technologies affected by the ionosphere has been steadily expanding. Technologies such as Global Positioning System, which have become indispensable in modern society, can suffer from degraded accuracy due to ionospheric structures.

Modeling Regional Electric Field Using EISCAT3D Observations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract EISCAT3D, which is in its final stage of construction, will be the next generation incoherent scatter radar (ISR) system to provide the full ion velocity vector across hundreds of kms in vertical and horizontal directions. This presents a tremendous opportunity to study the three‐dimensional nature of ionospheric electrodynamics.

The Performance of DIXSG on Characterizing Global and Regional Ionospheric Disturbances Utilizing Geodetic Receiver Network‐A Case Study

Space Weather, Volume 23, Issue 10, October 2025.
Abstract As the 25th solar cycle enters a highly active phase, the resulting ionospheric irregularities induce disturbances in signals of Global Navigation Satellite System (GNSS), significantly disrupting its global stable positioning, navigation, and timing services.

Characteristics of Large‐Scale Traveling Ionospheric Disturbances During the 10 May 2024 Geomagnetic Storm

Space Weather, Volume 23, Issue 10, October 2025.
Abstract Based on the total electron content (TEC) observation in the Asian‐Australian and American sectors, this paper investigates the characteristics and hemispheric asymmetry of large‐scale traveling ionospheric disturbances (LSTIDs) during the 10 May 2024 superstorm. We found that the amplitudes and meridional phase velocities of LSTIDs in the two

Ionospheric Disturbances During the 4 December 2015, Mt. Etna Eruption

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract This study presents the detection and characterization of co‐volcanic ionospheric disturbances (CVIDs) associated with Mt. Etna's large‐scale lava fountain (Italy). Leveraging a dense and proximal GNSS network, we identify local Total Electron Content (TEC) perturbations extending up to ∼ ${\sim} $200 km south/southwest of the vent.

Quasi‐Constant Time Gap in Multiple Rings of Elves

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract We present evidence that the time delay between the multiple rings of elves is not caused by the ground reflection of the electromagnetic pulse produced by intracloud lightning. To investigate temporal differences of multi‐elves, we analyzed data from four storms occurring at various times and distances from the Pierre Auger Observatory in ...

The Thermosphere Was Poorly Predictable Not Only During but Also Before and After the Starlink Storm on 3–4 February 2022

Geophysical Research Letters
Observation‐based simulations of the ionosphere were performed with the NRLMSISE‐00 model for six locations around the globe during 1–9 February 2022, which includes the so‐called Starlink Storm. Unlike other studies, we focused on the magnetically quiet

Artificial Neural Network Model of High‐Latitude Ionospheric Electric Potential: Hemispheric and Equinoctial Asymmetries

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract The high‐latitude ionospheric electric field plays a key role in ionospheric plasma dynamics and energetics. Various ground‐ and satellite‐based observations have been utilized to develop empirical models of the convection electric field. Empirical modeling typically relies on statistical regression techniques, where predefined functions are ...
