Coincident ENA and Narrowband Radio Emissions as Diagnostics of Inward Plasma Transport at Saturn

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Saturn's kilometric radiation (SKR) and Energetic Neutral Atom (ENA) emissions are important diagnostics of the planet's magnetospheric dynamics, intensifying during global plasma injections and displaying characteristic planetary periodicity. Related to the SKR emissions are myriametric narrowband radio emissions that typically appear in the ...

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

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

Foreshock Ion Properties at Earth's Bow Shock: Dependence on Upstream Conditions and Shock Geometry

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Solar wind ion reflection at collisionless shocks regulates foreshock plasma dynamics, yet the quantitative dependence of foreshock ion properties on upstream and shock‐related parameters remains unclear, causing difficulties in predicting foreshock disturbances.

Near‐Earth Cosmic Ray Modulation Index ϕ and Neutron Monitor Cutoff Rigidities at Hourly Cadence: Toward an Improved Monitoring of Solar‐Terrestrial Radiation Environment, Space Weather, and Space Climate

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic rays (CRs) are energetic particles originating from galactic and extragalactic sources. When arriving into the solar system and the Sun's heliosphere, they are diverted and modulated by the magnetic activity of the Sun. This modulation can be quantified by the modulation parameter ϕ $\phi $ determined with the Force‐field approximation (
