Global Wind Field Reconstruction in the Mesosphere and Lower Thermosphere (MLT) During Geomagnetic Storms by Fusing TIDI and SABER Data: A Generative Adversarial Network (GAN) Approach

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
ABSTRACT The Mesosphere and Lower Thermosphere establish an essential connection between Earth's lower atmosphere and upper atmosphere because wind patterns essential for atmospheric movement also influence energy distribution and chemical movements during geomagnetic storms that disrupt satellite operations and space weather prediction systems.

Electron Scattering by Highly Oblique Quasi‐Electrostatic Chorus Waves Under Realistic Magnetospheric Conditions

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Using Van Allen Probes data (2013–2015), we report that highly oblique chorus waves frequently occur in low‐density regions where fpe/fce≈3 ${f}_{\text{pe}}/{f}_{\text{ce}}\approx 3$. These waves exhibit an electric‐to‐magnetic energy ratio PE/c2PB>0.5 $\sqrt{{P}_{\mathrm{E}}/{c}^{2}{P}_{\mathrm{B}}} > 0.5$, much higher than the typical <0.1 ${

Bounce Resonance Between ULF Waves and Electrons in the Dayside Outer Magnetosphere

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Resonant interactions between ultra‐low‐frequency (ULF) waves and particles are critical for energy transfer in the Earth's magnetosphere, and have been extensively investigated in the inner magnetosphere. However, resonant processes between ULF waves and electrons in the dayside outer magnetosphere remain largely unexplored.

Contrasting Mechanisms of Heatwave‐Ozone Pollution Compound Events and Independent Heatwave Events in the Yangtze River Delta

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Heat waves do not always coincide with ozone pollution, yet the mechanisms controlling their divergence remain insufficiently understood. Here, we investigate why some heat waves evolved into heatwave‐ozone pollution compound events (HWOP), whereas others remained isolated heat wave events (IHW), over the Yangtze River Delta during summer 2024.

How the Relative Contribution of DP‐1 and DP‐2 Currents Reshapes the Global Current System During Substorms

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Geomagnetic disturbances in polar regions can be decomposed into two main patterns: the Disturbance Polar (DP) 1 and 2. How their relative contribution reshapes global current system remains unclear. In this study, we classified substorms from 2010 to 2022 into weak and strong DP‐2 events based on the ratio of the eastward to westward auroral ...

A 100-degree lithospheric magnetic field model constructed using MSS-1, Swarm-A, and CHAMP satellite data

Earth and Planetary Physics
By combining data from the Challenging Minisatellite Payload (CHAMP), Swarm-A, and newest Macau Science Satellite-1 (MSS-1) missions, we constructed a lithospheric magnetic field model up to spherical harmonic degree N = 100.

Influence of different data selection criteria on internal geomagnetic field modeling

Earth and Planetary Physics
Earth’s internal core and crustal magnetic fields, as measured by geomagnetic satellites like MSS-1 (Macau Science Satellite-1) and Swarm, are vital for understanding core dynamics and tectonic evolution.

MSCM: A geomagnetic model derived from Swarm, CSES, and MSS-1 satellite data and the evolution of the South Atlantic Anomaly

Earth and Planetary Physics
Measurements from geomagnetic satellites continue to underpin advances in geomagnetic field models that describe Earth’s internally generated magnetic field. Here, we present a new field model, MSCM, that integrates vector and scalar data from the Swarm,

Lithospheric long-wavelength magnetic anomalies and their geological origins: A review

地球与行星物理论评
At the altitude of low-Earth-orbiting satellites, most details of lithospheric magnetic anomalies observed near surface are attenuated, and only slowly decaying long-wavelength magnetic anomalies can be detected.
