The May 2024 Storm: The Cusps and Dayside Magnetopause in Simulated Soft X‐Rays

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The coronal mass ejection (CME) arriving at Earth on 10 May 2024 caused the most intense geomagnetic storm in the last two decades, resulting in highly unusual cusp and magnetopause dynamics. We simulate soft X‐Ray emission due to solar wind charge exchange with exospheric neutrals to image the global dayside dynamics, focusing on the impact ...

Seasonal and Diurnal Variability of Thermospheric Metastable Helium Observed by Multi‐Platform Observations and Numerical Modeling

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Metastable helium (He∗ ${\text{He}}^{\ast }$) in the thermosphere emits at 1,083 nm and provides a powerful diagnostic of thermospheric composition, solar radiation, and transport. Its detection remains challenging because of its extremely low density and high‐altitude.

Quasi‐Homologous Solar Flares and Impacts on Thermospheric Density and Satellite Orbital Drag

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Quasi‐Homologous Flaring (QHF) activity from active regions on the Sun releases intense electromagnetic radiation in recurrent bursts over extended periods. In this letter, we present the effects of recurrent impulsive extreme ultraviolet (EUV) heating on thermospheric neutral density and the resulting atmospheric drag on satellites based on ...

Tidal Variability in the Lower Thermosphere: Relative Importance of ENSO, QBO, PJO, MJO, and Lyα

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Atmospheric tides in the lower thermosphere play an important role in regulating upper‐atmospheric conditions relevant to space weather. However, their spatial and temporal variability remains poorly understood, apart from seasonal variations. Previous studies have shown that tides can be influenced by meteorological and solar conditions. This

Measuring and Mapping Urban NO2 Pollution Heterogeneity Using a Custom Pandora Spectrometer Experiment and Observations From TEMPO

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Nitrogen dioxide (NO2) is a primary pollutant present at high concentrations in urban areas. Ground based measurements remain sparse and satellite observations rely on retrievals, so understanding intraurban, diurnal‐scale changes in NO2 is challenging.
