On the location and structure of the artificial 630-nm airglow patch over Sura facility [PDF]
, 2007 International audienceResults are presented of the artificial optical emission of the atomic oxygen red line (the radiation of level O(1D) with a wavelength of 630 nm) from the HF-pumped ionosphere, obtained in September 2004 at the SURA heating facility

HF pump-induced electron heating and artificial airglow at high latitudes: Aspect angle dependence [PDF]
, 2002 Large electron temperature increases (~3000 K) in the ionospheric F-region, produced by powerful HF wave injection, were measured using the EISCAT incoherent scatter radar near Tromsø, Norway, on 7 October 1999.

The first coordinated observations of mid-latitude E-region quasi-periodic radar echoes and lower thermospheric 557.7-nm airglow [PDF]
Annales Geophysicae, 2005 We present the first coordinated observations of quasi-periodic (QP) radar echoes from sporadic-E (Es) field-aligned irregularities (FAIs), OI 557.7-nm airglow, and neutral winds in a common volume over Shigaraki, Japan (34.9° N, 136.1° E) on the ...

Computing uncertainties in ionosphere‐airglow models: II. The Martian airglow [PDF]
Journal of Geophysical Research: Space Physics, 2012 One of the objectives of spectrometers onboard space missions is to retrieve atmospheric parameters (notably density, composition and temperature). To fulfill this objective, comparisons between observations and model results are necessary. Knowledge of these model uncertainties is therefore necessary, although usually not considered, to estimate the ...

Simulation and analysis of radiant intensity for critical [PDF]
E3S Web of ConferencesAtmospheric oxygen A-band (759-767nm) airglow has strong radiation intensity in the visible band, and the global atmospheric temperature field can be obtained based on the oxygen A-spectrum line.

The observation of chemiluminescent NiO* emissions in the laboratory and in the night airglow [PDF]
Atmospheric Chemistry and Physics, 2011 The recent finding of an orange spectral feature in OSIRIS/Odin spectra of the night airglow near 87 km has raised interest in the origin of the emission.

Ultrafast Kelvin waves in the MLT airglow and wind, and their interaction with the atmospheric tides [PDF]
Annales Geophysicae, 2018 Airglow and wind measurements from the Brazilian equatorial region were used to investigate the presence and the effects of the 3–4-day ultrafast Kelvin waves in the MLT.

Earth and Planetary Physics, 2017 One of the important effects of the ionospheric modification by high-power waves is the airglow enhancement. Both the thermal electrons and the dissociation recombination contribute to generate the airglow emissions during HF heating.
