Simultaneous Observations of Quasi‐Orthogonal Nighttime MSTIDs at Conjugate African‐European Midlatitude Stations on 4 October 2018

Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract Two quasi‐orthogonal nighttime medium‐scale traveling ionospheric disturbances (MSTIDs) were observed by conjugate midlatitude all‐sky imagers in Sutherland (32.4° ${}^{\circ}$S, 20.8° ${}^{\circ}$E; magnetic latitude: ∼ ${\sim} $−40.9° ${}^{\circ}$) and Asiago (45.87° ${}^{\circ}$N, 11.53° ${}^{\circ}$E; magnetic latitude: ∼40.3° ${\sim} 40.3{

Approximation of Daily AMS‐02 Spectra With Machine Learning Methods

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Almost three thousand daily AMS‐02 proton spectra from 2011 to 2019 offer the most precise and extensive data set of cosmic ray spectra covering a wide energy range. As such, they offer a unique opportunity to test machine learning algorithms for approximating cosmic ray proton spectra based on the inputs usually available to solar modulation ...

Evolution of Terrestrial Planetary Bodies and Implications for Habitability

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.

A Comparative Study of VTEC Estimates Derived From S/X VLBI and VGOS Observations

Space Weather, Volume 23, Issue 12, December 2025.
Abstract The ionosphere, which strongly varies in time and space, is one of the largest error sources for microwave measurements, if not accounted for accurately. Especially for single‐frequency observations, precise ionospheric models are needed to correct for the ionospheric delays. This study explores the utility of Very Long Baseline Interferometry
