Abstract
The Atmospheric Ultraviolet Radiance Analyzer (AURA) has been designed to furnish global UV emissions measurements in the 115-175 nm range of sufficient sensitivity for observations of the weak emissions from the tropical arcs and the aurora from a nearly circular high-inclination orbit. Excellent S/N is obtained by AURA in the case of day airglow measurements. Two UV observation channels are available, each of which is based on a 1/8 Ebert-Fastie spectrometer and a telescope with a scanning mirror; each can furnish data in any one of three operational modes.
