Abstract : The solar spectrum from 3390/cm to 4060/cm as observed through the earth's atmosphere was measured during a balloon flight on September 30, 1965, at Chico, California. The atmospheric spectral transmittance for altitudes up to 3 1 km are presented both graphically and in a tabular form. The integrated absorption for each spectrum is also tabulated at 1/2 wavenumber intervals. The water vapor absorption measured at floating altitude is shown to increase proportional to (sec theta 0) to the 1/2 power thus precluding significant absorption contributions from local outgassing. Assuming uniform mixing above 3 1 km, the mixing ratio for water vapor is 0.00005 g/g, consistent with earlier results. (Author)
