Abstract

We describe a sounding rocket experiment to investigate mechanisms governing the interactions between two of the fundamental components of the solar-terrestrial system: the solar ionizing radiation and the Earth's upper atmosphere. The experiment was designed to characterize the Extreme Ultraviolet (EUV) emissions resulting from these interactions in terms of physical parameters so that EUV remote sensing can be gainfully employed as a quantitative diagnostic of the terrestrial atmosphere and plasma environment. Although several EUV observations of the Earth's airglow have been made, these measurements have never been complemented with simultaneous measurements of the solar EUV flux, thereby making the interpretations somewhat ambiguous. The payload consisted of (1) a high resolution (-1.5 Å) spectrometer to measure the EUV emissions (980-1360 A) of the Earth's dayglow, (2) a moderate resolution (-10 Å) EUV spectrometer (250-1450 Å), to measure the solar irradiation responsible for the photoelectron production, and (3) a hydrogen Lyman Alpha photometer to monitor the solar irradiance and geocoronal emissions. The experiment was con-ducted from a four-stage Black Brant XII sounding rocket launched from NASA Wallops Flight Facility in Wallops Island, Virginia, on September 30, 1988.
