Night airglow phenomenology

Semiannual oscillation of the mesospheric airglow at 7.4°S during the PSMOS observation period of 1998–2001

“…In the present work, a database of the OI5577 mesospheric component, O2b and OH(6,2) intensities, and TOH, with more than 6 h of continuous observation per night, was used to analyze the nocturnal, day-to-day and seasonal variations. The mesospheric component of OI5577 was obtained by subtracting the ionospheric F region component estimated as 20% of the simultaneously observed OI630 nm intensity (Silverman, 1970).…”

Seasonal variations of the nighttime O(1S) and OH (8‐3) airglow intensity at Adelaide, Australia

“…This is typically observed [e.g., Donahue et al , ; Fukuyama , ; Takahashi et al , ; Deutsch and Hernandez , ; Clemesha et al , ; Liu and Shepherd , ], although the response typically shows some hysteresis in that the decline in the emission intensity after solar maximum is slower than the decline in solar activity. Silverman [] discussed the variation of 558 nm intensity with solar cycle at some length and noted that a number of authors had found that the dependence was not symmetric over the solar cycle. Indeed, whether a sinusoid as fitted here is the best form is fit is not obvious given the form of the F 10.7 cm flux or sunspot number (rapid rise and slower falloff).…”

On the Origin of STEVE: Particle Precipitation or Ionospheric Skyglow?

“…Other optical emissions observed in the Earth's upper atmosphere are collectively known as airglow (and often referred to as dayglow or nightglow; Solomon, , and references therein). Airglow is the emission of light at discrete wavelengths throughout the spectrum and is produced by chemical reactions of incoming solar radiation with atoms and molecules in the upper atmosphere (Silverman, ; Solomon, ).…”
