Airglow monitoring by one-pixel detector
Nuclear Instruments and Methods in Physics Research Section A : Accelerators, Spectrometers, Detectors and Associated Equipment, 2019The night time airglow is a dynamic phenomenon that acts as a background for the detection of the extensive air shower (EAS) fluorescence. It is a mandatory task to monitor this background for the ground-based telescopes and for the planned space-based ...

HF induced airglow: Double patches!
Physics and Chemistry of the Earth, Part B: Hydrology, Oceans and Atmosphere, 2000Abstract HF induced airglow has been observed at high latitudes on 21 February 1999 during a geomagnetically quiet period (Kp=1). This observation is unique because two patches were generated simultaneously on one occasion. The EISCAT Heating experiment (69.59° N, 19.23° E) was operated at 4.04 MHz (O-mode) in the local zenith from 16:48 to 18:28 UT ...

Airglow I: Four Main Airglow Emissions
2002Airglowln a dark moonless night away from city light, a certain amount of light is observed to come from space whereby big letters can be read. Excluding light from stars, zodiac, galaxies and that scattered by the atmosphere, it is observed that the remaining light, which is about 40%, is produced by self luminescence of atmosphere.

Abstract Airglow OH emissions originate from the mesopause and provide optical signatures of various physical and chemical processes occurring in this region of the upper atmosphere. Emissions from different vibrational levels of the mesopause OH (in the ground electronic state) may peak at different heights. roughly between 80 and 90 km.

Variations of airglow intensity, Volume Emission Rate (VER), and VER peak height induced by the CO2 increase, and by the F10.7 solar cycle variation and geomagnetic activity were investigated to quantitatively assess their influences on airglow.

Jupiter's Nightside Airglow and Aurora
Science, 2007Observations of Jupiter's nightside airglow (nightglow) and aurora obtained during the flyby of the New Horizons spacecraft show an unexpected lack of ultraviolet nightglow emissions, in contrast to the case during the Voyager flybys in 1979. The flux and average energy of precipitating electrons generally decrease with increasing local time across the

Abstract This survey of excitation processes for singlet O 2 in planetary atmospheres is intended to provide an introduction to the following papers in which laboratory investigations and field measurements are discussed in more detail. The three singlet states, a 1 Δ g , b 1 Σ g + and c 1 Σ u − , contribute to features in the airglows of ...
