OHS: OH-airglow Suppressor for the Subaru Telescope [PDF]
, 2000 This paper describes an OH-airglow Suppressor (OHS) for the infrared Nasmyth focus of the Subaru telescope. OHS has the capability of eliminating 224 airglow-lines in the $J$- and $H$-bands, which are major sources of background radiation at near ...

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.

Journal of Geophysical Research: Space Physics, 2020 Near‐epicentral mesopause airglow perturbations, driven by infrasonic acoustic waves (AWs) during a nighttime analog of the 2011 M9.1 Tohoku‐Oki earthquake, are simulated through the direct numerical computation of the 3D nonlinear Navier‐Stokes ...

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.

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 ...

Observations of the Near-infrared Spectrum of the Zodiacal Light with CIBER [PDF]
, 2010 Interplanetary dust (IPD) scatters solar radiation which results in the zodiacal light that dominates the celestial diffuse brightness at optical and near-infrared wavelengths.

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 ...

Measurements of the Diffuse Ultraviolet Background and the Terrestrial Airglow with the Space Telescope Imaging Spectrograph [PDF]
, 2000 Far-UV observations in and near the Hubble Deep Fields demonstrate that the Space Telescope Imaging Spectrograph (STIS) can potentially obtain unique and precise measurements of the diffuse far-ultraviolet background.
