INVESTIGATION OF THE INFRARED EMISSION SPECTRUM OF THE ATMOSPHERE AND EARTH.

Abstract

Comparisons between sky emission measurements in the window region of 4.7 microns, and transmission measurements over a path length of about 35o m with emissivities and transmissivities calculated from the transmission data of PLASS, STULL, and WYATT indicate that the theoretical data have to be corrected by a factor of o.2 - o.4. Scattered solar radiation could not be indicated in the sky emission spectrum at 4.7 microns by a comparison of day- and nighttime measurements. Extinction coefficients were derived from interference filter actinograph measurements, and were used in an investigation about the continuum absorption in the near infrared windows. Further developments in the construction of a helicopter radiometer for measurements of the scattered solar radiation are reported. (Author)
