Nightside Detection of a Large‐Scale Thermospheric Wave Generated by a Solar Eclipse
Geophysical Research Letters, 2018 The generation of a large‐scale wave in the upper atmosphere caused by a solar eclipse was first predicted in the 1970s, but the experimental evidence remains sparse and comprises mostly indirect observations. This study presents observations of the wind

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract During the geomagnetic storm on 10 May 2024, neutral density measurements from 14 Tianmu, Swarm, and GRACE‐FO satellites at ∼510 km altitude, combined with total electron content (TEC) observations, enabled the first global observational comparison of large‐scale traveling atmospheric and ionospheric disturbances (LSTADs/TIDs) via snapshots ...

Green Emissions of Atomic Oxygen at Sprite Tops Explained
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Green emissions from excited Oxygen in Sprite Tops (GhOSTs) are due to the 557 nm photons emitted from atomic oxygen (O) $(\mathrm{O})$ excited to the 1S state. In this work we compare the possible contribution of various mechanisms for excitation of O(S1) $\mathrm{O}({}^{1}S)$ under application of a lightning‐induced electric field to the ...

AGU Advances, Volume 7, Issue 3, June 2026.Abstract Strong Thermal Emission Velocity Enhancement (STEVE) is a nightsky optical phenomenon of great research interest in recent years. STEVE is recognized to be co‐located with a latitudinally narrow channel of fast westward ion drifts, also known as “subauroral ion drifts” (SAID).

Nitrogen oxides and the airglow
, 2021 The chemospheric processes lead to various possibilities for description of the contribution of nitrogen oxides in the airglow. An excitation of the Vegard-Kaplan system is indicated when nitric oxide is formed by a three-body collision process involving
