Physics‐Based Ensemble of Models for F2 Peak Parameters of the Ionosphere: Comparison With COSMIC‐2 Measurements

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Space weather events can significantly alter the ionospheric electron density, affecting signal transmission and navigation accuracy in satellite‐based systems. Consequently, there is an urgent need for reliable forecasting of the Thermosphere‐Ionosphere (TI) system.

Evaluating the Accuracy of Magnetospheric Magnetic Field Models Using Cluster Spacecraft Magnetic Field Measurements

Universe, 2021
Magnetic fields in the inner magnetosphere can be obtained as vector sums of the Earth’s own internal magnetic field and magnetic fields stemming from currents flowing in the space plasma. While the Earth’s internal magnetic field is accurately described

Evolution of Reversed Electron Energy Spectra in Earth’s Radiation Belts Observed by CIRBE

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Following an intense geomagnetic storm (Dst < −150 nT) on 5 November 2023, electron fluxes in the outer radiation belt were reduced by more than three orders of magnitude at energies below ∼700 keV while they were enhanced at ∼1–3 MeV, leading to reversed energy spectra.

Parameterization of the Latitudinal Dependence of ULF Waves in the Magnetosphere via Long‐Term Statistical Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Ultra‐low frequency (ULF) waves are crucial drivers of energetic electron radial diffusion in Earth's radiation belts. However, present radial diffusion coefficients are predominantly derived for equatorially mirroring electrons, relying on ULF wave power models from near‐equatorial spacecraft.

Neural Network Imputation of the Pitch‐Angle‐Resolved Medium‐Energy Electron Flux Data in LEO

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Pitch‐angle‐resolved electron flux data are crucial for investigating variations in electron flux within the magnetosphere and the underlying mechanisms, such as radial diffusion and wave‐particle interactions. The Medium‐Energy Electron Detector (MEED) onboard the Fengyun‐3E (FY‐3E) satellite in Low Earth Orbit (LEO) provides 18‐directional ...

Integrated Multi‐Physics Characterisation of the Northern Kiruna Mining District With Machine‐Learning‐Assisted Interpretation

Geophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Integrated earth modelling aims to combine all available geoscientific information to derive one common earth model. However, combining multiple parameters in a meaningful way remains challenging. In this study, we aim to improve mineral exploration workflows through the integration of new magnetotelluric data with other geophysical and ...
