Toward a Dynamic Model for Topside Ionospheric Irregularities: Spherical Harmonic Decomposition

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Ionospheric irregularities arise from highly dynamic and turbulent processes related to magnetosphere‐ionosphere coupling and can lead to electromagnetic signal distortion or loss of lock events in global navigation satellite system signals, representing a hazard associated with space weather events. For this reason, understanding and modeling

Fifty-year investigation of the correlation between the geomagnetic field and climate

地球与行星物理论评
After 50 years of research on the correlation between the geomagnetic field and climate, we have gained a deeper understanding that the regulation of climate by geomagnetic field changes is far more complex than previously imagined.

Machine Learning‐Ready Data Sets for the Analysis and Nowcasting of Atmospheric Radiation at Aviation Altitudes

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Nowcasting and forecasting of the radiation environment in the Earth's lower atmosphere are critical for the safety of aircraft and spacecraft crews and passengers. Currently, this problem is addressed by employing statistical and physics‐based models that take into account particle transport and precipitation.

Analysis of Ionospheric Correlation Time Variations Based on Long‐Term GIMs Data

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Ionospheric correlation time measures the temporal correlation of the ionosphere and is an important parameter for characterizing the temporal connection of ionospheric variability. Ionospheric correlation times are obtained from high resolution global ionospheric TEC maps spanning 2005 to 2020.

Analysis on Global Es Layer Response to the May 2024 Geomagnetic Storm Through a Combination of Tianmu‐1 and COSMIC‐2 Radio Occultation Observations

Space Weather, Volume 24, Issue 3, March 2026.
Abstract The sporadic E (Es) layer, a key manifestation of ionosphere‐neutral atmosphere coupling, is highly sensitive to geomagnetic storms. Using more than 25,000 daily radio occultation profiles from the Tianmu‐1 and COSMIC‐2 constellations, this study investigates the global response of the Es layer to the May 2024 storm.

Climatology of Equatorial Plasma Bubbles: Role of Gravity Wave Seeding and Ionospheric Preconditioning

Space Weather, Volume 24, Issue 3, March 2026.
Abstract This study investigates the linkage between mesopause gravity waves and equatorial plasma bubbles (EPBs) from 2012 to 2015 using the collocated nightglow measurements, O2 (762 nm) and OI (630 nm), observed by the Visible and near‐Infrared Spectral Imager onboard the International Space Station under the Ionosphere, Mesosphere, upper Atmosphere,

Global Ultra-Low-Frequency Geomagnetic Pulsations Associated with the March 24, 1991 Geomagnetic Storm

Terrestrial, Atmospheric and Oceanic Sciences, 2008
On 24 March 1991, global ultra-low-frequency (ULF) pulsations (1.1 - 3.3 mHz) observed in the magnetosphere as well as on the ground were studied via analyzing magnetic field data obtained from a global network, comprising ground-based observatories and ...

Validation of Ionospheric Models at Mid‐ and High‐Latitudes: Climatological Performance of WACCM‐X (SD) and TIE‐GCM in foF2

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Modeling the high‐latitude ionosphere‐thermosphere system is imperative to understanding the impacts of space weather on modern technology, such as communications and navigation systems. At low‐ and mid‐latitudes, physics‐based and empirical models are well‐developed and capture the variability of the ionosphere to a good degree of accuracy ...

Application of a recently developed method of oriented drill coring to accumulative tephra layers: identification of the Matuyama–Brunhes geomagnetic reversal in Akan caldera-forming eruption deposits

Earth, Planets and Space
We adapted a recently developed technique of oriented drill coring (100 m in depth) for paleomagnetic measurements, including additional techniques such as half-cutting of the drill cores and accurate cube sampling using an apparatus that precisely ...
