Measuring 557.7 NM Airglow Changes Associated with Upper Atmospheric Ion Cloud Releases

Abstract

Ground-based airglow measurements at 557.7 nm were conducted during the SECEDE II barium cloud releases to gather information on a proposed coupling between the ion clouds and the E-layer through charge transport. The twilight background signal at release time was found to be too large for the measuring the small effect with the available equipment. After the tests the field data were used in an instrument performance study. The results of this study will be useful in designing equipment for future measurements of this type.
