Abstract
This article analyzed annual, seasonal and daily variations of total solar and ultraviolet (UV) radiation, based on observed data over Nanjing area from May 2001 to April 2002. The study shows that the daily variation of solar radiation and UV-radiation is bigger at noon, smaller in the morning and afternoon. When looking at it on an annual scale the variation is bigger in summer, smaller in winter. A linear regression equation has been set up to calculate quantities of UV-radiation that reaches the earth in a sunny day from daily-observed data.
