Equatorial F‐Region Responses to the Main Phase of the 10 May 2024 Geomagnetic Storm Over the South American Sector: Observations and Model Simulations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study examines the equatorial ionospheric response over the South American sector during the onset of the extreme 2024 Mother's Day geomagnetic storm, which began at ∼17 UT on 10 May and reached the G5 level. Pronounced disturbances in ionospheric electrodynamics were observed under both daytime and nighttime conditions. Variations in the

Coordinate Systems and Transforms in Space Physics: Terms, Definitions, Implementations, and Recommendations for Reproducibility

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract In space physics, acronyms for coordinate systems (e.g., GEI, GSM) are commonly used; however, differences in their definitions and implementations can prevent reproducibility. In this work, we compare definitions in online resources, software packages, and frequently cited journal articles and show that implementation differences can lead to ...

Coupled Thermosphere–Ionosphere Dynamics During the 17 January 2013 Storm: GITM–TIDAS Comparison With Millstone Hill ISR Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This article analyzes a weak geomagnetic storm on January 17–18, 2013, using a first‐principles model (Global Ionosphere Thermosphere Model (GITM) with an empirical assimilative ionospheric model (TIDAS), evaluated against observations in the form of Millstone Hill (MH) incoherent scatter radar (ISR) altitude profiles and global navigation ...
