A low- or middle-latitude, more or less steady, faint photochemical luminescence visible in the upper atmosphere at night.


(Physical Geography) the faint light from the upper atmosphere in the night sky, esp in low latitudes

The object was below the airglow," Detlef Koschny, who studies near-Earth objects for the ESA, said in the agency's blog post on the fireball.
Shepherd and York University colleague Youngmin Cho studied unusual airglow profiles in the satellite data and found 11 events that showed an increase in airglow levels that would be visible to the human e/e.
To achieve this, the datasets of the two years were corrected for the changing light effects caused by the moon as well as 'seasonal vegetation, clouds, aerosols, snow and ice cover, and even faint atmospheric emissions (such as airglow and auroras) which change the way light is observed in different parts of the world.
BGU and TAU have already submitted a joint proposal to study Earth's airglow layer.
Tenders are invited for Photometer :- Airglow temperature imaging photometer will provide airglow intensity and rotational temperature and their spatial variability to study wave dynamical effects related to gravity waves, tides, planetary waves in the mesosphere and lower thermosphere.
WASHINGTON (CyHAN)- Bright swaths of red in the upper atmosphere, known as airglow, can be seen in this video captured by the International Space Station.
While Earth imaging has been the main focus of the research on CubeSat imaging systems [8-15], other applications, such as star tracking [12,16-19], horizon tracking [12,16], attitude calibration [20], proximity monitoring [8,17,21-23], heliospheric imaging [24], and airglow observations [25,26] have also been presented.
The guests of honour on this occasion included Lord Rayleigh (Robert Strutt, the fourth Baron Rayleigh) who was the first person to differentiate between the two types of natural light from the night sky, namely the aurora and the airglow.
