Definition of the Subject and Its Importance

Solar UV radiation is the most energetic radiation that is able to penetrate the atmosphere and reach the Earth’s surface. Due to the very low intensities of the radiation in this wavelength range, its investigation started comparably late with respect to the other spectral regions of the solar spectrum. Dorno was the first to investigate systematically the seasonal and spectral variability of solar UV radiation at Davos, Switzerland. Starting in 1907, his measurements allowed to determine the distinct differences of radiation in this wavelength range, which were later explained by the absorption of atmospheric ozone (mainly located in the stratosphere). Using a specially designed spectroradiometer, he discovered the relationship between the cut-on of the solar spectrum in the UV-B and the path through the atmosphere. In view of his achievements, UV radiation at the time was also called Dorno radiation . In the 1960s, Paul Bener, also...
