Ozone depletion in the stratosphere is now recognized as a major environmental problem, because which results in a significant increase in solar ultraviolet radiation that reaches the surface of the Earth. The purpose of this study is to know daily accumulations of DUV, which is one of the biologically weighted ultraviolet radiation, corresponding to cloud amount and simplified weather classification. Through analysis of observed spectral ultraviolet irradiances, global solar radiation and cloud amounts at Sapporo, Kanazawa, Tsukuba, Kagoshima and Naha, the followings were shown : (1)The level of daily accumulated DUV at 5 observation points. (2) The relation between DUV and cloud amount. (3) The daily accumulated DUV corresponding to simplified weather classification in each region and in each month.
