Convective Amplification of Ionospheric Feedback by a Finite‐Duration Inertial Alfvén‐Wave Source

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract We investigate the ionospheric feedback instability (IFI) driven by a finite‐duration localized source of inertial Alfvén waves. Wave‐excited conductance perturbations undergo Pedersen mobility drift in the convection and wave electric fields and are amplified.

Local Generation of Plasmaspheric Plume Hiss

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The statistical analysis of hiss waves observed in the plasmaspheric plume (Wu et al., 2026, https://doi.org/10.1029/2026gl121667) is significant for identifying nonlinear wave growth processes in the equatorial region. Because nonlinear growth rates greatly exceed linear growth rates, they enable the local generation of new wave packets in ...

Meter‐Scale Roughness of the Lunar Surface

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Small‐scale surface roughness is a key indicator of local geological processes, yet it has not previously been mapped globally on the Moon. We present global meter‐scale surface roughness maps generated from the Lunar Orbiter Laser Altimeter pulses, which record information about surface undulations within the instrument's ∼5 m individual ...

Cosmogenic 10Be as a Tracer for Recent Heliospheric Encounters With Interstellar Cold Clouds and Nearby Supernovae

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interstellar galactic cosmic rays and energetic particles of heliospheric origin.

Drift‐Resonance Driven by Field Line Resonance Gradients: A Mechanism for Non‐Dispersive Microinjection Events

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Ultra‐low‐frequency waves in the magnetosphere often produce field line resonances with strong spatial gradients in wave amplitude. We analyze a form of drift resonance driven by these gradients near the resonant field line. This mechanism differs fundamentally from conventional gradient‐ and curvature‐driven drift resonance and predicts an ...
