Paper Abstract

Over the next five years the Naval Research Laboratory (NRL) will fly a series of ultraviolet satellite instrument packages to measure vertical profiles of atmospheric airglow emission. The objective of this program is to test new techniques for optical remote sensing of the mesosphere, thermosphere, and ionosphere using limb scanning spectrographs. Emphasis will be placed on day- and night-remote sensing of the F-region through measurement of profiles of airglow emission from the O+ ion. Other objectives include remote sensing of vertical profiles of neutral density, minor species and temperature. These observations will be used to study the composition, photochemistry, thermodynamics, and couplings between atmospheric regions. A phased approach will be used which provides for: (1) comprehensive multi-parameter measurements; (2) high spectral resolution studies; and (3) long-term operational observations from DoD weather satellites. The first of these payloads is the multi- sensor experiment called the remote atmospheric & ionospheric detection (RAIDS). RAIDS, a collaboration between NRL and The Aerospace Corporation, contains two spectrographs, three scanning grating spectrometers, and three photometers. Space flight for RAIDS will be provided by the Air Force Space Test Program (STP). The phase 2 component is the high resolution airglow/aurora spectroscopy (HIRAAS) experiment, a collaboration between NRL and the Naval Postgraduate School. HIRAAS will fly aboard the STP ARGOS Satellite in early 1996. The third phase of this program involves flight of a series of five limb scanning instruments called the special sensor ultraviolet limb imager (SSULI) aboard Defense Meteorological Satellite Program weather satellites in the last quarter of this decade. The long- term observations from these satellite experiments will provide a comprehensive database of mesospheric, thermospheric, and ionospheric density profiles from which to search for the effects of global change.
