Airglow Information and Ionospheric Processes [PDF]
, 1986 308-323A brief analysis on the airglow as an indicator of the ionospheric processes is made. Ionospheric-magnetospheric interaction and interrelation between neutral and ionizing components are examine.

Statistics and variability of the altitude of elves
Geophysical Research Letters, 2016 From June 2008 to January 2016 nearly 800 elves have been recorded by a low‐light camera in northeastern Spain. Elves occur in this region mainly over the lower topped cold air mass maritime thunderstorms, peaking from November to January.

HF-induced airglow at magnetic zenith: theoretical considerations [PDF]
Annales Geophysicae, 2005 Observations of airglow at 630nm (red line) and 557.7nm (green line) during HF modification experiments at the High Frequency Active Auroral Research Program (HAARP) heating facility are analyzed.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract This study presents a cross‐comparison of mesosphere and lower thermosphere (MLT) neutral temperatures between 88 and 110 km measured by ICON/Michelson Interferometer for Global High‐resolution Thermospheric Imaging (MIGHTI) and Thermosphere Ionosphere Mesosphere Energetics and Dynamics/Sounding of the Atmosphere using Broadband Emission ...

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Flares originate from the impulsive release of magnetic energy in the solar atmosphere. The rise in X‐ray flux enhances ionization/electron content in the upper atmosphere, modifying the photochemical and dynamical processes that govern the ionosphere‐thermosphere behavior.

First observation of the Venus UV dayglow at limb from SPICAV/VEX
Geophysical Research Letters, 2012 We present the first limb observations of the dayglow emissions by the UV channel of SPICAV aboard Venus Express between October and December 2011. The CO Cameron bands between 180–260 nm and CO2+ doublet at 289 nm are clearly identified for the first ...

Can the International Reference Ionosphere Model Predict Long‐Term Trends in the Ionosphere?
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The International Reference Ionosphere (IRI) model can partially reproduce ionospheric long‐term trends (LTTs), although not intentionally, provided that an appropriate effective ionospheric index is used. We evaluate how model predictions driven by a solar activity proxy (R12) and by an effective ionospheric proxy (IG12) can reproduce the ...
