| Abstract: | A two stream model has been used to calculate the variation of optical depth and their effects to ultraviolet radiation of each extinction material.With the model,the relation among season,solar zenith angle and ultraviolet radiation has been discussed,and the variation of ultraviolet radiation under different clouds has also been studied.The comparative research of ultraviolet radiation among Kunming,Beijing and other abroad area at the same latitude has also been done. |

| Keywords: | ultraviolet radiation two stream model optical depth |
