Ultraviolet spectroscopy and remote sensing of the upper atmosphere
TL;DR: A review of the field of airglow analysis can be found in this article, where the basic processes leading to excitation of atomic and molecular energy states are discussed and the current status of knowledge of individual emission features seen in the air glow is examined for the purpose of selecting those species most useful as diagnostics of the state of the upper atmosphere and ionosphere.

Longitudinal structure of the equatorial anomaly in the nighttime ionosphere observed by IMAGE/FUV
TL;DR: In this article, the authors examined the global characteristics of the nighttime equatorial anomaly (EA) by constructing a constant local time map (LT map), in which pixels within an assigned local time range are extracted from the IMAGE/FUV nightglow images obtained over an observation period of 3 days or more and are put together to compose a global distribution map of emission intensities at that local time.

Satellite vacuum ultraviolet airglow and auroral observations
TL;DR: In this article, global observations of the airglow, aurora, and solar scatter radiance of the earth's atmosphere have been made in the 1100- to 2900-A wavelength region.

Excitation of oxygen permitted line emissions in the tropical nightglow
Brian A. Tinsley,Andrew B. Christensen,J. A. Bittencourt,H. Gouveia,P.D. Angreji,H. Takahashi +5 more
TL;DR: In this article, it is concluded that radiative recombination is the major source of the tropical oxygen permitted line emissions, accompanied by a small contribution from ion-ion recombination.

Geocoronal hydrogen: An analysis of the Lyman-alpha airglow observed from OGO-4
R. R. Meier,P. Mange +1 more
TL;DR: In this article, OGO-4 observations of hydrogen Lyman-alpha airglow surrounding earth, measuring dependence on solar zenith angle, were used to measure the dependence of the solar zener angle on the Lyman alpha airglove surrounding earth.

Electron Impact Excitation of the Dayglow
TL;DR: Equilibrium velocity distributions of F region photoelectrons produced by solar ionizing radiation, discussing dayglow as impact result as mentioned in this paper, discussed day glow as the impact result and discussed the impact of solar ionization radiation.

Quenching of metastable states of atomic and molecular oxygen and nitrogen
TL;DR: In this article, the quenching coefficients of O2 and N2 were investigated by means of a combination of laboratory and observational data, and it was found that O2 has very small quench coefficients, whereas N2 has a higher quench coefficient approaching the gas-kinetic value.

Calculations of auroral intensities from electron impact
TL;DR: In this article, the energy deposited in the excited states of N2, O2, and O from the slowdown of electrons in the 0.1-30-kev range is calculated from extensive sets of electron impact cross sections of Green et al.
