Excitation of vibrational emission bands in aurora and airglow

Abstract

The major results of the theoretical study of infrared radiation in the vibrational-rotational bands of minor molecular constituents in the terrestrial thermosphere are reviewed. Various mechanisms of vibrational excitation of radiating molecules are discussed for both quiet and disturbed conditions (e.g., aurorally enhanced electric fields, etc.). Intensities of infrared emissions and correlations between some of them and emissions in other spectral regions are analyzed, as well as the role that infrared radiation plays in the thermospheric energetics.On revoit les principaux rtsultats de I'Ctude theorique du rayonnement infrarouge dans les bandes de vibration-rotation des constituants molCculaires mineurs dans la thermosphkre terrestre. On discute differents mecanismes d'excitation vibrationnelle des molCcules rayonnantes, dans des conditions paisibles ou perturbees (champs Clectriques intensifies par I'aurore, par exemple, etc ...). Les intensites des Cmissions infrarouges, ainsi que les corrClations entre certaines d'entre elks et les Cmissions dans d'autres regions spectrales sont analysCes, de m&me que le r61e jouC par le rayonnement infrarouge dans I'CnergCtique thermospherique.[Traduit par la revue]Can.

Vibrational Kinetics of NO and N2 in the Earth's Middle Atmosphere During GLE69 on January 20, 2005

“…The primary sources of vibrationally excited NO in the upper atmosphere have been discussed by Kockarts (1980), Caledonia and Kennealy (1982), Gordiets et al. (1982), Gordiets (1986), Sharma et al. (1996), Kirillov and Aladjev (1998), Cartwright et al.…”

The purpose of those papers was to examine the mechanisms responsible for the production of NO(X 2 Π,v > 0) in the upper atmosphere and infrared radiation of NO under quiescent and aurorally excited conditions.…”

Special attention in the papers was devoted to the infrared 5.3 and 2.7 μm emissions of NO molecules radiated in the spontaneous transitions…”
