Description

Today, the ozone depletion in the stratosphere is recognized as a major environmental problem, because which results in a significant increase in solar ultraviolet (UV) radiation that reaches the surface of the Earth. The CFC utilized as a refrigerant of air conditioner causes the ozone layer depletion. The purpose of this study is to clarify the change with the time in the clear sky day on DUV, which is one index of the biologically weighted ultraviolet solar radiation, in order to make the ultraviolet radiation defense effective at the individual action level. Through analysis of observed spectral ultraviolet irradiances, UV-B, UV-A and global solar radiation at Kanazawa Institute of Technology, the followings were shown : (1) The distinctive feature of DUV change by the time in a day compared to global solar radiation. (2) The difference of DUV values per unit flux of global solar radiation by the season. (3) The existence of the size of DUV value between morning and afternoon.
