The influence of the Earth's magnetosphere on the high-energy solar protons [PDF]

open access: yes
In the Earth's polar regions the intensity of the solar protons with the energy above the critical energy of geomagnetic cutoff is the same as in the interplanetary space. The penumbra in the polar regions is small and the East-West effect is also small.

Frequency‐Dependent Latitudinal Distributions of Plasmaspheric Plume Hiss Directionality and Amplitude

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Plasmaspheric plume hiss plays a crucial role in shaping Earth's electron radiation belts and influencing magnetosphere–ionosphere energy coupling. However, its generation mechanism remains contested between cyclic‐linear and localized‐nonlinear models. By analyzing over 64,000 high‐resolution plume hiss wave segments from the Van Allen Probes

Magnetopause Boundary Layers in Low Mach CME‐Driven Storm Environment

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Magnetopause boundary layers (BLs) play an important role mediating plasma and energy exchange between the solar wind/magnetosheath and Earth's magnetosphere. Energy exchange across the magnetopause is enhanced during storms, yet little work has been done investigating BLs during storms.

Error enhancement in geomagnetic models derived from scalar data [PDF]

open access: yes
Models of the main geomagnetic field are generally represented by a scalar potential gamma expanded in a finite number of spherical harmonics. Very accurate observations of F were used, but indications exist that the accuracy of models derived from them ...

Nonlinear Gyrokinetic Simulation of the Magnetosphere‐Ionosphere Feedback Coupling

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract A nonlinear gyrokinetic simulation is applied to the magnetosphere‐ionosphere (M‐I) coupling system to investigate spontaneous growth of auroral structures and electron acceleration self‐consistently. Perturbations of electron density, potential and field‐aligned current in the auroral ionosphere develop through the feedback instability ...
