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.

Observations of Atmospheric Radiation Increases During GLE 77 From New Airborne and Ground Level Instruments

Space Weather, Volume 24, Issue 10, October 2026.
Abstract On 11 November 2025, at approximately 10:20 UTC, the 77th Ground Level Enhancement (GLE) occurred. This paper presents a comprehensive data set encompassing observations from ground‐level neutron monitors across the United Kingdom (UK), radiation monitors on radiosonde flights from the UK and the Netherlands, and radiation monitors onboard ...

Shark preferences: Only subtle effects of electromagnetic field exposure and substrate type on small‐spotted catshark (Scyliorhinus canicula) behaviour

Journal of Fish Biology, Volume 109, Issue 4, Page 2166-2178, October 2026.
Abstract Offshore wind energy plays a crucial role in the transition to low‐carbon power generation. The expansion of offshore wind farms (OWFs) introduces anthropogenic electromagnetic fields (EMFs) from subsea power cables. Elasmobranchs, including sharks and rays, are sensitive to natural electric and magnetic fields used for navigation and prey ...

The Dense MORB Fraction Controls the Dynamic Stability and Hydration Potential of the Mantle Transition Zone

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The mantle transition zone (MTZ; ∼410–660 km depth) is a major reservoir of water and mid‐ocean ridge basalt (MORB)‐like materials, yet how composition and hydration regulate its physical stability remains unclear. Using geodynamical modeling, we examine the joint effect of water content and dense MORB fraction on the density, viscosity, and ...

Chorus Wave‐Induced Ionospheric Variability

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Electron microbursts are short‐lived but intense electron precipitation and constitute a significant source of electron losses into the ionosphere and lower atmosphere. They are primarily produced by wave‐particle interaction with chorus waves in the magnetosphere.

Neutral Wind Control of Jupiter's Non‐Auroral Ionosphere

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract We use JAMMIES (JAMMIES is Another Model Making Ionospheric EStimates), a new model of Jupiter's non‐auroral ionosphere, to demonstrate that neutral wind‐driven field‐aligned plasma transport can explain decades of measurements inconsistent with a solar‐dominated ionosphere. Two observations highlight these inconsistencies: a minimum in H3+ ${\
