TLDR
Emission features from ionized carbon dioxide and carbon monoxide were measured and the Lyman alpha 1216-angstrom line of atomic hydrogen and the 1304-, 1356-, and 2972-angston lines of atomic oxygen were observed.Abstract:
Emission features from ionized carbon dioxide and carbon monoxide were measured in the 1900- to 4300-angstrom spectral region. The Lyman alpha 1216-angstrom line of atomic hydrogen and the 1304-, 1356-, and 2972-angstrom lines of atomic oxygen were observed.read more

The composition of the atmosphere at the surface of Mars
TL;DR: The current status is summarized of investigations of the Martian atmosphere, in which use was made of the mass spectrometers that function as the analytical component of the molecular analysis experiments on the two Viking landers.

Ionization, luminosity, and heating of the upper atmosphere of Mars
Jane L. Fox,Alexander Dalgarno +1 more
TL;DR: In this article, a model based upon Viking data is constructed of the Martian atmosphere, and a comprehensive quantitative discussion is given of the measurements of the ultraviolet dayglow, and detailed assessment is made of the heating of the neutral and ionized components of the atmosphere arising from the absorption of ultraviolet solar radiation.

Mariner 6 and 7 Ultraviolet Spectrometer Experiment: Analysis of hydrogen Lyman-alpha data
TL;DR: In this article, the authors analyzed four Lyman alpha airglow measurements of the limb and disk of Mars, made by ultraviolet spectrometers on Mariner 6 and 7 in 1969 and Mariner 9 in 1971, to determine the amount and distribution of atomic hydrogen above 80 km.

Rocket measurement of the nitric oxide dayglow
TL;DR: A scanning ultraviolet spectrometer was flown from Wallops Island, Virginia, on NASA Aerobee 4.85 on November 17, 1963, at 1:15 P.M. EST to an altitude of 184 km as mentioned in this paper.

Planetary ultraviolet spectroscopy.
TL;DR: Ultraviolet spectroscopy can determine if the atoms and molecules basic to life are present in a planetary atmosphere: in particular, molecular nitrogen and the photodissociation products of water vapor.

Rocket spectrophotometer airglow measurements in the far ultraviolet
TL;DR: In this paper, the results of three rocket spectrophotometer flights which studied far ultraviolet night and day airglow in the earth's atmosphere above 100 km were presented, where the results were obtained for the 1216 A Lyman α radiation of atomic hydrogen, both night and daylight, and dayglow profiles for the 1304 and 1356 A atomic oxygen and the 1200 A atomic nitrogen emission.
