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.

Atmosphere, 2020 630.0 nm all-sky imaging data are used to detect airglow depletions associated with equatorial spread F. Pairs of imagers located at geomagnetically conjugate locations in the American sector at low and mid-latitudes provide information on the occurrence

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.

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.

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.

Geophysical Research Letters, 2019 This paper reports a special midlatitudinal medium‐scale traveling ionospheric disturbance (MSTID) event, accompanied by a poleward surge of airglow depletion/enhancement and a bifurcation of depletion during the magnetically quiet period.

Simplified Relations for the Martian Night-Time OH* Suitable for the Interpretation of Observations
Remote Sensing, 2022 Observations of excited hydroxyl (OH*) emissions are broadly used for inferring information about atmospheric dynamics and composition. We present several analytical approximations for characterizing the excited hydroxyl layer in the Martian atmosphere ...

Extraction of Quasi-Monochromatic Gravity Waves from an Airglow Imager Network
Atmosphere, 2020 An algorithm has been developed to isolate the gravity waves (GWs) of different scales from airglow images. Based on the discrete wavelet transform, the images are decomposed and then reconstructed in a series of mutually orthogonal spaces, each of which
