DTIC AD0752115: Approximate Values of Intensity of Natural Ultraviolet Radiation for Different Amounts of Atmospheric Ozone

The present report deals with the results of measurements and computations of ultraviolet sky, solar, and sun+sky (global) intensity for 15 wavelengths between lambda = 297.5 and 380 nm and for 12 values of total amount of atmospheric ozone covering the interval of 0.240 to 0.460 cm in increments of 0.020 cm. The variation of ultraviolet intensity in dependence on Northern Latitude and season and the influence of an assumed reduction of atmospheric ozone is examined. The variation of the short wavelength limit of the terrestrial solar spectrum is furthermore discussed. The results on ultraviolet intensity for selected values of ozone and solar altitude are presented in tables. Diagrams demonstrate the variation of global intensity in dependence on the principal parameters. The present data are based on the results of extensive measurements of ultraviolet sky intensity at Davos, Switzerland (1950 m a.s.l.), and completed by a theoretical computation of direct solar intensity for elevations of 0 to 5 km s.s.l.
