Gravity Wave Activity in the Stratosphere and Mesosphere During Hurricane Sam

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Multi‐instrument observations of gravity wave (GW) activity during Hurricane Sam (2021) were made using AIRS (Atmospheric Infrared Sounder) satellite data, ERA5 reanalysis, and TIMED/SABER temperature profiles. Two GW extraction methods, vertical high‐pass filtering and empirical mode decomposition, were applied to quantify wave‐induced ...

Analysis for the results of geomagnetic storms measured by Macau Science Satellite-1

Earth and Planetary Physics
Strong flares and/or coronal mass ejections (CMEs) could bring us disastrous space weather, destroy crucial technology in space, and cause a large-scale blackout during some extreme cases.

RESPONSE OF BIOLOGICAL SYSTEMS TO GEOMAGNETIC STORMS

Acta Biomedica Scientifica, 2018
At present, influence of weak magnetic fields associated with solar and geomagnetic activity on biological systems is gaining more interest. Taking into account the accumulated data on the influence of geomagnetic storms on different biological levels ...

Height‐Dependent Evolution of the Ionospheric Response to the May 2024 Superstorm: Global GNSS‐POD, GNSS‐RO, and Ground‐Based Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Capturing global ionospheric response during extreme geomagnetic storms remains a major observational challenge. During 10–11 May, 2024 superstorm, we investigate the height‐dependent response of the F‐region using multi‐constellation GNSS‐POD limb‐sounding measurements from COSMIC‐2, Spire, PlanetiQ, and FengYun‐3 satellites. Approximately 12,

Probing the high latitude ionosphere from ground-based observations: The state of current knowledge and capabilities during IPY (2007-2009) [PDF]

, 2008
During the International Polar Year (IPY), one area of great interest is co-coordinated, multi-instrument probing of the ionosphere at high latitudes. This region is important not only for the applications that rely upon our understanding of it, but also

Comparing Solar Structure Detection Methods in SDO/AIA Observations and the Application to Raw Uncalibrated Data

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Recent advances in solar physics increasingly rely on automated identification of coronal structures using machine learning. Yet most studies emphasize scientific performance without evaluating feasibility for onboard deployment to prioritize downlink observations.

WACCM‐RR: A Regionally‐Refined Version of the Whole Atmosphere Community Climate Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract We introduce the Whole Atmosphere Community Climate Model with Regional Refinement (WACCM‐RR) and study the impact of directly resolving gravity waves (GWs) in the mesosphere and lower thermosphere (MLT; 70–140 km). Two simulations of 2010 are compared: “Non‐RR” is a standard WACCM case with a horizontal resolution of ∼1° (111 km) globally ...
