The Spectrum of the Airglow

The Spectrum of the Airglow

Discussion of the nightglow, and description of the features that are peculiar to the twilightglow and the dayglow. It is pointed out that the airglow is the faint light emitted when atoms and molecules are dissociated high in the atmosphere. Its spectra yield clues to the physical conditions and ch...

Zusammenfassung:Discussion of the nightglow, and description of the features that are peculiar to the twilightglow and the dayglow. It is pointed out that the airglow is the faint light emitted when atoms and molecules are dissociated high in the atmosphere. Its spectra yield clues to the physical conditions and chemical processes in the region.
