Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract The observations from GRACE‐FO and DMSP satellites are utilized to analyze the ion‐neutral interaction near dusk during the 10–12 May 2024 super‐storm. The horizontal plasma convection dragged the anti‐sunward wind in the polar cap and sunward winds around the auroral and subauroral regions during whole storm times.

Atmospheric and Ionospheric Responses to Hunga‐Tonga Volcano Eruption Simulated by WACCM‐X
Geophysical Research Letters, 2023 High‐resolution Whole Atmosphere Community Climate Model with thermosphere/ionosphere extension is used to simulate the responses to the Hunga‐Tonga volcano eruption on 15 January 2022.

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract A new proton radiation belt was identified during the geomagnetic superstorm of 10–11 May 2024. To investigate its origin, we use an MHD‐test particle simulation to model solar energetic proton (SEP) trapping and the evolution of the initial trapped proton population during the storm.

Determination of the most pertinent EUV proxy for use in thermosphere modeling
, 2011 International audience[1] Two major issues in the specification of the thermo-spheric density are the definition of proper solar inputs and the empirical modeling of thermosphere response to solar and to geomagnetic forcings.

Open Magnetic Field Lines Partition Auroral Oval Segments Into Transpolar Arcs
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Transpolar arcs (TPAs) are auroral structures spanning the polar cap. One type appears in conjugate hemispheres and is thought to be located on closed field lines, but how closed flux enters the open polar cap remains debated. We address this using observation and simulation of conjugate TPAs after an interplanetary magnetic field (IMF) By ...

The stability of short-period extrasolar giant planets [PDF]
, 2008 A three-dimensional coupled thermosphere-ionosphere model for extrasolar giant planets (EXOTIM) has been developed. This is the first such model reported in the literature.

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract The atmosphere and ionosphere form a vertically coupled system in which disturbances in the lower atmosphere can modulate ionospheric variability. Using reanalysis data, ground‐based GNSS observations, and COSMIC‐2 profiles, we investigate gravity waves (GWs) generation and upward coupling during a southwest vortex (SWV) event over the Tibetan

AGU Advances, Volume 7, Issue 3, June 2026.Abstract In Low Earth Orbit (LEO), atmospheric drag is the dominant source of trajectory prediction error below approximately 700 km altitude, primarily due to inaccuracies in thermospheric density models. This work presents a method for temporally deconvolving Energy Dissipation Rates (EDRs) to produce single‐satellite density estimates, which can be ...
