Atmospheric ozone profiles from high resolution UV spectra obtained with a balloon-borne spectrometer.

High resolution solar spectra at high and low sun angles in the 3200-3400-A region were obtained during balloon flights on 9 Feb. 1977 (altitude 41 km) and 17 Feb. 1977 (altitude 29 km). These data were analyzed using a layer-by-layer three-wavelength differential absorption method. Ozone volume-mixing ratio profiles, which agree with standard profiles, were derived. Suggestions are made for improving the accuracy of the results in future measurements.
