Early Morning Equatorial Ionization Anomaly From GOLD Observations
Journal of Geophysical Research: Space Physics, 2020 AbstractDuring geomagnetically quiet and solar minimum conditions, spatial variations of the early morning thermosphere‐ionosphere (TI) system are expected to be mainly governed by wave dynamics. To study the postmidnight dynamical coupling, we investigated the early morning equatorial ionization anomaly (EIA) using Global‐scale Observations of the ...

Reverse Fountain and the Nighttime Enhancement in the Ionospheric Electron Density Over the Equatorial Region: A Case Study [PDF]
, 2020 This paper focuses on the linkage between reverse fountain effect and anomalous enhancement in the nighttime electron density over the equatorial ionosphere often referred as the ionospheric nighttime enhancement (INE). The Global Positioning System (GPS)

Reconfiguration of Mercury's Exosphere During Strong Space Weather Events
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Mercury is exposed to various space weathering processes, which alter the surface and cause emission of atoms and molecules into the exosphere. The exosphere thus allows remote insights into the surface composition and erosion processes, with the emission of refractory elements such as Ca and Mg typically being dominated by micrometeoroid ...

Characterizations of the diurnal shapes of OI 630.0 nm dayglow intensity variations: inferences [PDF]
Annales Geophysicae, 2002 Measurements of OI 630.0 nm thermospheric dayglow emission by means of the Dayglow Photometer (DGP) at Mt. Abu (24.6° N, 73.7° E, dip lat 19.09° N), a station under the crest of Equatorial Ionization Anomaly (EIA), reveal day-to-day changes in the ...

Neutral Wind Control of Jupiter's Non‐Auroral Ionosphere
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract We use JAMMIES (JAMMIES is Another Model Making Ionospheric EStimates), a new model of Jupiter's non‐auroral ionosphere, to demonstrate that neutral wind‐driven field‐aligned plasma transport can explain decades of measurements inconsistent with a solar‐dominated ionosphere. Two observations highlight these inconsistencies: a minimum in H3+ ${\

Space Weather, Volume 24, Issue 9, September 2026.Abstract This study presents a survey of high‐latitude ionospheric scintillation using GNSS radio occultation (RO) data from the PlanetiQ satellite. The analysis examines 483 high‐latitude RO tracks between January and May 2023, with 371 tracks exhibiting scintillation events.
