Nitrogen oxides and the airglow

The chemospheric processes lead to various possibilities for description of the contribution of nitrogen oxides in the airglow. An excitation of the Vegard-Kaplan system is indicated when nitric oxide is formed by a three-body collision process involving molecular nitrogen. A bimolecular association leading to nitrogen peroxide must show a continuous airglow during dark hours as well as in a sunldit atmosphere. Electronic systems emission of NO2 is also possible because of a reaction between ozone and nitric oxide. A reaction leading to an excitation of the O2 red atmospheric band system with its peculiar emissions is also discussed. Since these various processes causing day, twilight, and night airglow occur in the mesosphere and at the mesopause level, dynamic effects may lead to strong variations in the airglow.
