Variation of the Infrared Solar Spectrum between 2800 and 5100 cm^−1 with Altitude*

Abstract

A prism spectrometer capable of scanning the region from 2800 to 5100 cm-1 was flown on a balloon in conjunction with a biaxial pointing control 17 January 1963. Spectra were obtained at various altitudes from the ground through 23 km. These data are presented in this report. The experimental results are compared with the spectra calculated using results given by Zachor. The total absorptances are also compared with theoretical values predicted using procedure suggested by Plass and the laboratory results of Howard, Burch, and Williams.
