Electrical Conductivity of Hydrous Ultramafic Melts With Implications for Origin of Low Velocity Layer Atop of the 410 km Seismic Discontinuity

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Low‐velocity layers (LVLs) above the 410‐km discontinuity are commonly attributed to partial melt generated by dehydration melting when hydrous mantle transition‐zone material rises into the upper mantle, where water solubility in nominally anhydrous minerals decreases.

Residual Magnetization Accumulation Enables Rapid Pre‐Polarized Surface NMR Groundwater Detection

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Surface nuclear magnetic resonance (SNMR) directly detects subsurface water, but its field application is constrained by the trade‐off between signal enhancement and survey throughput. Conventional pre‐polarization strengthens SNMR signals but requires long polarization pulses that markedly prolong acquisition. Here we show that repeated short

Ultra‐Low‐L Sub‐MeV Electron Microbursts During the May 2024 Super Storm

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract During the May 2024 super storm, we identified sub‐second microburst‐type relativistic electron precipitation events at McIlwain's L∼2 $L\sim 2$ in low‐Earth orbit using the Gamma‐ray Burst Monitor (CGBM) onboard the CALorimetric Electron Telescope on the International Space Station.

Latitudinal Discrepancy Between Thermospheric Density and Temperature Associated With Neutral Composition Effect

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In this study, multi‐source thermospheric observations and TIEGCM simulations were used to explore the latitudinal variations of thermospheric temperature and total mass density at equinoxes. At nighttime, temperature and density exhibit consistent latitudinal patterns, with higher values at high latitudes.

Physics‐Aware AI‐Driven 4D Temperature Reconstruction With Enhanced Non‐Uniform Vertical Resolution in Near Space (20–80 km)

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Near‐space temperature is crucial for atmospheric dynamics and aerospace applications, yet data sets with refined vertical resolution remain scarce. We present the Atmospheric Spatio‐Temporal Reconstruction Network (AtmoST‐Net), which integrates high‐resolution SABER observations with dual‐source reanalysis, combining non‐uniform vertical ...
