Abstract : The infrared solar spectrum from 1 to 10 microns was observed at various altitudes from the ground to 90,000 ft over Alamogordo, N. Mexico, April 18, 1960. By studying the variation with altitude of the 6.3 micron water vapor band and making certain assumptions concerning the pressure dependence of the absorption, it has been possible to determine the distribution of water vapor with altitude up to 90,000 ft. The method used is discussed in detail. The results are presented as an altitude profile of the mixing ratio and are found to be in good agreement with the results obtained by other investigators using different techniques. The amount of water vapor present above the peak altitude reached by the balloon is also determined from the spectra. It is found that there was at least 11 microns of precipitable water vapor present above 90,000 ft over Alamogordo at the time of the flight. (Author)
