| Abstract: | A method of calculating the solar ultraviolet radiation reaching the ground over Beijing area is proposed, and the primary and secondary contribution of dominant factors affecting the solar ultraviolet radiation reaching the ground surface under the clear sky condition and actual sky condition are analysed. Possible extinction mechanism of the solar ultraviolet radiation reaching the earth's surface by water vapour which takes part in the most atmospheric photochemical reactions is discussed in detail. |
