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 ...

TRACERS Small‐Scale Field‐Aligned Currents and Intense GPS Amplitude and Phase Scintillations in the Nightside Auroral Region

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We present conjugate observations of ionospheric small‐scale magnetic perturbations (dB) $(dB)$ and GPS scintillations from the Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) and the Canadian High Arctic Ionospheric Network (CHAIN) during a storm‐time substorm on 9 August 2025 in the nightside auroral region ...

Synchronous Advance of the Alpine Glaciation Across the Northern and Southern Tibetan Plateau During the Mid‐Pleistocene Transition

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Chronological studies of glacial sediments from the Shishapangma and Yarlung Tsangpo River valley indicate that Quaternary glaciation on the southern Tibetan Plateau commenced at ∼0.75–0.83 Ma. However, the oldest glacial deposits in the northern plateau are dated to only ∼0.46 Ma, markedly later than the Middle Pleistocene glacial ...

Physics‐Embedded Deep Learning Reveals the Memory Effect of Ionospheric Electron Density in Response to Solar EUV Forcing

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Precise characterization of the electron density profile is crucial for optimizing high frequency communications. Reconstruction models often assume an instantaneous ionospheric response to solar forcing or using time delays, neglecting the time‐integrated cumulative “memory effect” of plasma dynamics.
