Plasma Properties at the Orbits of Ganymede and Callisto: Survey of Juno Data

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The space environment around the Galilean moons is important for understanding the interaction of the magnetospheric plasma with their magnetosphere (in the singular case of Ganymede), their atmospheres and surfaces. Juno's orbital evolution brought the spacecraft close to the orbits of Ganymede and Callisto on multiple occasions over several ...

Variation of Global Ionospheric Scintillation and Its Effect on GPS Kinematic PPP‐AR Performance During Geomagnetic Storms in Solar Cycle 25: A Statistical Analysis

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Enhanced small‐scale ionospheric irregularities during geomagnetic storms can disturb Global Navigation Satellite System (GNSS) carrier‐phase tracking and are associated with reduced stability of ambiguity‐fixed precise point positioning (PPP‐AR), but their impact on kinematic positioning remains insufficiently quantified.

Ionospheric Mechanisms Leading to Plasma‐Bubble Zonal Drift Reversal and Deformation During the 12 November 2025 Geomagnetic Storm

Space Weather, Volume 24, Issue 10, October 2026.
Abstract We present a multi‐instrument analysis of the ionospheric response to the intense geomagnetic storm of 12 November 2025 over the American sector, with emphasis on the longitudinally asymmetric deformation, latitudinal expansion, and zonal drift reversal of equatorial plasma bubbles (EPBs).

ScintPi 4.0: A New GNSS‐Based Low‐Cost, Multi‐Constellation, Multi‐Frequency Ionospheric Scintillation and TEC Monitor for Education, Citizen Science, and Research Initiatives

Space Weather, Volume 24, Issue 10, October 2026.
Abstract ScintPi is a series of alternative ionospheric scintillation and total electron content (TEC) monitors. ScintPi monitors have been built by combining single‐board computers (Raspberry Pi) and commercial off‐the‐shelf (COTS) Global Navigation Satellite System (GNSS) receivers.

Modeling African equatorial ionosphere using ordinary Kriging interpolation technique for GNSS applications

, 2018
The ability to model the ionosphere accurately for single frequency users in satellite applications has gained some appreciable usage, most especially during quiet conditions in a mild (middle latitudes) ionosphere.

Observation of Shortwave Fadeout Events Using Chinese Dual Auroral Radar Network (CN‐DARN) During the Severe Solar Storm in May 2024

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Shortwave fadeout (SWF) is a typical dayside high‐frequency radio disturbance caused by solar flare‐induced ionospheric ionization enhancement. Using newly built Chinese Dual Auroral Radar Network (CN‐DARN) observations, we investigate two X‐flare‐driven SWFs during the May 2024 geomagnetic superstorm (SYM‐H = −518 nT), on 10 May (pre‐storm ...

Global Ionospheric TEC Forecasting Driven by a Unified Physical Index System via the Spectral Whitening Method

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Accurate forecasting of global ionospheric total electron content (TEC) is important for Global Navigation Satellite Systems (GNSS) performance and satellite communications. This study proposes a driver framework based on the spectral whitening method (SWM). We combine a new high‐latitude geomagnetic disturbance index with previously developed
