Simulating Bouncing Packets Driven by Ducted Lightning‐Generated Whistlers: Comparison With SAMPEX Observations

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Bouncing packets are quasi‐periodic microbursts separated by the electron bounce period. Solar Anomalous and Magnetospheric Particle Explorer observations revealed relativistic (>1 MeV) inner‐belt bouncing packets with “crown,” “decaying,” and “flat” envelopes.

Observational Analysis on the Relationship Between Chorus Waves and MeV Microburst Electron Precipitation

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Microbursts are thought to be a key contributor to radiation belt electron loss, with chorus waves considered a primary driver of this precipitation. However, the conditions under which chorus waves produce MeV electron loss remain poorly constrained.

IMF By‐Controlled Dawn–Dusk and Hemispheric Asymmetries of Kelvin–Helmholtz Waves and Reconnection Geometry Under Negative Dipole Tilt

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Along with magnetic reconnection, Kelvin‐Helmholtz (KH) waves are the main mechanisms controlling the solar wind‐magnetosphere interaction, enabling plasma transport into the magnetosphere due to secondary reconnection, diffusion and wave‐particle interactions.

Evolution of Reversed Electron Energy Spectra in Earth’s Radiation Belts Observed by CIRBE

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Following an intense geomagnetic storm (Dst < −150 nT) on 5 November 2023, electron fluxes in the outer radiation belt were reduced by more than three orders of magnitude at energies below ∼700 keV while they were enhanced at ∼1–3 MeV, leading to reversed energy spectra.

Early Eocene Compressional Deformation in the Northeastern Tibetan Plateau Recorded by Magnetic Fabrics of the Longzhong Basin

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Intracontinental deformation records how early Eocene India–Asia collisional stress propagated into continental interiors. How rapidly compression reached the far field, and whether coeval Paleo‐Pacific slab dynamics contributed, remain debated. The Longzhong Basin, ∼1,900 km north of the collisional zone, provides a key test.

Repeat Station Activities

, 2011
A repeat station is a site whose position is accurately known and where accurate measurements of the geomagnetic field vector are made at regular intervals in order to provide information about the secular variation of the geomagnetic field.
