Spatial and Temporal Variability of SWIR Air Glow Measurements: Postprint
Abstract
It is well know that luminance from photo-chemical reactions of Hydroxyl ions in the upper atmosphere(-85 km altitude) produces a significant amount of night time radiation in the short wave infrared (SWIR) band between 0.9 and 1.7 um wave length. This has been demonstrated as effective illumination source for night time imaging applications. In addition it has been shown demonstrated as an effective illumination and be used to characterize atmospheric tidal wave actions in the sky glow region. These spatio-temporal variations manifest themselves as traveling wave patterns whose period and velocity are related to the wind velocity at 85km as well as the turbulence induced by atmospheric vertical instabilities. Ground to space observation systems especially those employing adaptive optics are adversely affected by high altitude turbulence and winds. In this paper we propose the use of sky glow observations to predict and characterize image system degradation due to upper atmosphere turbulence.
