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.

A Gaussian Process Regression Framework for Slant Ionospheric Delay Interpolation and Uncertainty Quantification With Applications to PPP‐RTK

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Reliable slant ionospheric information is crucial for Precise Point Positioning Real‐time Kinematic (PPP‐RTK), yet its correction in low‐latitude regions remains difficult because of ionospheric variability, observable anomalies, and insufficiently reliable uncertainty characterization.

Power Spectral Characteristics of Martian Ionospheric Irregularities

The Astrophysical Journal
The intrinsic magnetic field of a planet plays a key role in its ionospheric dynamics. Mars lacks a global magnetic field, thus ionospheric plasma is weakly coupled to crustal and induced magnetic field.

Drifting Ionospheric Scintillation Simulation for L-Band Geosynchronous SAR

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
An L-band geosynchronous synthetic aperture radar (GEO SAR) is susceptible to the ionospheric scintillation induced by ionospheric irregularities due to its lower carrier frequency.

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 ...

On the factors controlling occurrence of F-region coherent echoes [PDF]

, 2002
International audienceSeveral factors are known to control the HF echo occurrence rate, including electron density distribution in the ionosphere (affecting the propagation path of the radar wave), D-region radio wave absorption, and ionospheric ...

Mapping Space Weather Induced PPP‐AR Uncertainty to UAV Power‐Line Inspection Safety Risk

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Space weather can affect the reliability of satellite‐based positioning and thereby disrupt industrial operations that increasingly depend on Global Navigation Satellite System (GNSS) services. This concern is becoming more relevant with the rapid growth of the low‐altitude economy, where unmanned aerial vehicles (UAVs) are increasingly used ...

Type‐III Solar Radio Bursts at Mars: A 16.5‐Year Catalog From Mars Express‐MARSIS at 0.1–5.5 MHz

Space Weather, Volume 24, Issue 10, October 2026.
Abstract The most intense radio feature in the Solar System are the solar Type‐III radio bursts, which are associated with electron beams that propagate along open magnetic field lines. Although solar radio bursts have been studied since the 1940s, observations remain mainly restricted within 1 AU.
