SOME MEASUREMENTS OF SKY EMISSION IN THE 5-25 MICROMETER REGION

Abstract

An experimental study of the thermal radiation from the atmosphere is described, and some preliminary results are presented. These consist of moderately low-resolution spectra obtained with the instrument looking directly upward for various clear-sky weather conditions at Willow Run, Michigan. Comparisons are made with spectra representing band-model predictions based on standard atmospheric temperature and water vapor profiles adjusted to values measured at ground level. The agreement is satisfactory in the centers of the molecular bands; the uncertainties in the 10-12-micrometer continuum region are discussed.
