Investigations of Ultraviolet Emissions from the Ionosphere.

Abstract

The work of Contract F19628-93-C-0092 has improved the accessibility and utilization of databases containing ultraviolet (UV) measurements of the ionosphere obtained from satellite and Space Shuttle experiments. These experiments were the Ultraviolet Backgrounds on S3-4 satellite, the Auroral Ionospheric Remote Sensor (AIRS) on the PolarBEAR satellite, the Horizon Ultraviolet Program (HUP), and shuttles STS-4 and STS-39. These databases were used to analyze the ionosphere and to validate the Atmospheric Ultraviolet Radiation Integrated Code (AURIC). The S3-4 experiment measured the UV emissions from the ionosphere looking in nadir while in a polar orbit. Data were collected simultaneously from three instruments. The telemetry tapes, processed into VAX compatible tapes, are stored at the Phillips Laboratory/Geophysics Directorate, where they remain active in ionospheric analysis. The AIRS data contain a series of ionospheric images recorded mainly at high latitudes and at selected wavelength. These have been placed on a set of optical disks and are accompanied by software that allows quick looks at the images or the acquiring of a raw image for further processing. They have been used for comparisons with ground-based all-sky-camera measurements of the aurora and with the Defence Meteorologic Satellite Program (DMSP) measurements for Auroral Oval correlations. The Atmospheric Ultraviolet Radiance Analyzer (AURA) satellite instrument is functional and awaits final calibration.
