Abstract

EXCEDE is a Defense Nuclear Agency and Air Force Geophysics Laboratory program designed to study atmospheric radiative processes resulting from the controlled deposition of energetic electrons from rocketborne electron accelerators. On October 19, 1979, the 2600-kilogram EXCEDE SPECTRAL payload was successfully lauched from Poker Flat, Alaska, into a dark, clear and aurorally inactive night atmosphere. The stabilized payload contained: a 60 kilowatt (3 kV) electron accelerator, an array of ultraviolet, visible, and cryogenic infrared spectrometers, photometers, and both photographic film and video cameras. Atomic and molecular emissions induced in the atmosphere by the pulsed, rocketborne electron accelerator and radiating in the 0.15 to 22 micron wavelength region were recorded at altitudes from 70 to 128 km. Observed emissions included: the N2 Lyman Birge Hopfield system, the N2 Herman Kaplan system, the N2 first and second positive systems, the N2 Wu Benesch infrared system and the N 2 + first negative and Meinel systems.
