Morphological Features of Severe Ionospheric Weather Associated with Typhoon Doksuri in 2023

Remote Sensing
The atmospheric gravity waves (AGWs) generated by severe typhoons can facilitate the transfer of energy from the troposphere to the ionosphere, resulting in medium-scale traveling ionospheric disturbances (MSTIDs).

Beyond the Electrostatic Approach: Numerical Simulations of Martian Ionospheric Irregularities

AGU Advances, Volume 7, Issue 5, August 2026.
Abstract Numerical simulations play an essential role in the study of ionospheric irregularities. In the past few decades, electrostatic simulations have successfully simulated the nonlinear evolution of terrestrial ionospheric irregularities. However, the Mars Atmosphere and Volatile EvolutioN (MAVEN) observations reveal that the Martian ionospheric ...

Intercalibration of the Plasma Density Measurements in Earth's Topside Ionosphere

, 2021
Over the last 20 years, a large number of instruments have provided plasma density measurements in Earth's topside ionosphere. To utilize all of the collected observations for empirical modeling, it is necessary to ensure that they do not exhibit ...

Longitudinal Variation of Ionospheric Irregularities and Response of the Ionosphere During 10–13 May and 10–13 October 2024 Geomagnetic Storms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We examine the response of the ionosphere to the 10–13 May 2024 and 10–13 October 2024 geomagnetic storms, the two recent great geomagnetic storms of solar cycle 25. We identified the occurrence of ionospheric irregularities during the two geomagnetic storms.

The applicability of existing topside ionospheric models to the South African region

South African Journal of Science, 2010
The modelling of the electron density profile (Ne) for the topside ionosphere is challenging due to the limited availability of measured data. Over the past few years, a range of approaches to topside ionospheric modelling and representation of the Ne variation over the topside altitude range have been developed.

Investigating the Leptokurtotic Nature of Low‐Latitude GNSS Scintillations With a Multiscale Approach

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We investigate the statistical nature of Global Navigation Satellite System (GNSS) signal fluctuations through the multiscale analysis of a strong scintillation event recorded at the Ionospheric Observatory of the Luigi Broglio Space Center in Malindi, Kenya.

Influence of Magnetosonic Waves on the Venusian Ionosphere: The Role of Electron Landau Heating

The Planetary Science Journal
Plasma waves around terrestrial planets mediate energy transfer between electromagnetic fields and charged particles, significantly influencing the dynamics of their space plasma environments. While such interactions are well documented at Earth and Mars,

Assessing GNSS Reflectometry for High‐Latitude 3D Ionospheric Imaging

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract This study investigates whether Global Navigation Satellite System Reflectometry (GNSS‐R) measurements from low‐Earth‐orbit (LEO) satellites can improve three‐dimensional (3D) ionospheric electron density imaging, with a focus on high‐latitude regions. Conventional ionospheric tomography is limited by sparse ground‐based receiver coverage over

Four-Dimensional Topside Electron Density Modeling Using Multi-Stage Deep Learning Approaches

Remote Sensing
Accurate modeling of topside ionospheric electron density is essential for improving GNSS positioning and understanding upper-atmosphere dynamics. A new four-dimensional (spatial and temporal) topside electron density model is developed using global GNSS

Response of Topside Ionospheric Electron Density During Solar Flares Using 2014–2024 Swarm Satellite Measurements

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract This paper presents a global statistical investigation into the topside ionosphere electron density response to X‐class solar flares during geomagnetically quiet conditions (Kp ≤ $\mathit{\le }$ 2) using Swarm satellites (462–511 km) data from 2014 to 2024.
