Variation of the Infrared Solar Spectrum Between 700/Cm1 and 2240/Cm1 with Altitude

摘要

A grating spectrometer with a cooled detector was flown on three balloon flights. Spectra in the region from 4 microns to 14.3 microns were obtained at various altitudes from the ground through 30 km with a resolution considerably better than that achieved in previous flights. Some of the spectra were obtained over long paths at float altitude, during the sunset. Data from these flights are presented in this report with a discussion of the significant features of the observed absorptions. Special emphasis is put on the new features observed during the sunset.
