Assessment of Spacecraft Internal Charging in the Earth's Outer Radiation Belt

Space Weather, Volume 24, Issue 8, August 2026.
Abstract The internal charging effects triggered by energetic (>100 keV) electrons in the Earth's radiation belts can cause anomalies and failures of electronic components aboard spacecraft. Given the critical importance of safeguarding space assets, it is essential to estimate internal charging risks, which depend highly on the distribution of ...

Structurally‐Controlled Permeability Evolution and Mineralization in Geothermal Caprocks: The Fenice Capanne Mining District (Southern Tuscany, Italy)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The Neogene mineralized region of the Colline Metallifere in southern Tuscany (Italy) provides a natural laboratory to investigate feedback between fluid–rock interaction, structurally controlled fluid flow, and hydrothermal ore mineralization.

Sub‐MeV Electron Precipitation Driven by EMIC Waves: New Insights From CIRBE/REPTile‐2 Measurements

Geophysical Research Letters
Electromagnetic ion cyclotron (EMIC) waves are recognized as a key driver of relativistic (>1 MeV) electron loss in Earth's magnetosphere. Growing evidence also suggests that EMIC wave can efficiently scatter sub‐MeV electrons, although the precise ...

Quantifying Uncertainty in OMNI Solar Wind Measurements Projected From L1 to the Earth's Bow Shock

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Many routine measurements of the solar wind plasma and interplanetary magnetic field (IMF) are made at the L1 Sun–Earth Lagrange point; therefore, it is helpful to characterize the errors introduced in propagating these measurements to the near‐Earth environment.

Statistical Survey of Cosmic Noise Absorption in Conjunction With Plasma Wave Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Using a decade of observations from the Canadian Geospace Observatory Riometer Network (GO‐RIO), we selected an east‐west subset of stations near L∼7 $L\sim 7$ to classify cosmic noise absorption (CNA) (a proxy for enhanced D‐region ionization) into two morphologies, simultaneous and drifting, based on the relative timing of signals across the

Quasi‐Trapped Zebra Stripes: Radial Transport Driven by Dual‐Pulse Electric Fields

Geophysical Research Letters
Energetic electron spectra in Earth's inner radiation belt often exhibit regular stripe‐like features, known as “zebra stripes,” which are typically attributed to the drift motion of stably‐trapped electrons disturbed by electric field perturbations ...

Sensitivity of Bounce‐Averaged Diffusion Coefficients to the Latitudinal Variability of Lightning Generated Whistlers

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The development of statistical wave models that include the underlying variability of the wave distributions is an important next step toward more accurate radiation belt models. Lightning‐generated whistlers (LGW) are an important wave mode in the plasmasphere; previous time‐averaged diffusion coefficients have used assumptions about the wave

Global Validation of the Data‐Assimilative VERB‐3D Code for the Radiation Belts

Space Weather
Electrons within Earth's radiation belts exhibit large variability in space and time during geomagnetic storms, which could potentially damage satellites and harm astronauts in space.

Ray Tracing Method in a General Non‐Dipole Magnetic Field

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We present a new general mathematical formulation of the Eikonal equations for ray tracing, which can use any internal magnetic field model. The analytical and tractable expressions are conveniently based on a vector formalism, which is independent of any coordinate system.
