IR Atmospheric Measurements

Abstract

Atmospheric radiance data obtain enpassant during LWIR observations of satellites may be used to produce a near real-time extinction model for the 20 micrometers transmission window. Work is described and some interim results are presented on an experiment intended to characterize atmospheric absorption scaling with wavelength. Measuring precision of background limited radiometers is improved by long period signal averaging. A facility for accomplishing this is described. Radiant intensity measurements of asteroids and deep space satellites are presented.
