| 摘 要： | 通过辐射传输计算考察了火山气溶胶及Ｏ３变化对到达地面的不同波长紫外直射、漫射和总辐照度，以及ＵＶＢ辐照度的影响，对模拟结果与在北京西北郊实际观测到的皮纳托博火山喷发前后ＵＶＢ辐照度的变化作了比较，并就二差别的一些原因进行了讨论。

| Abstract: | Through radiation transfer calculations,the effects of variations in volcanic aerosols and ozone on direct,diffuse and total ultraviolet spectral irradiancies and UVB irradiancies arriving at the surface have been investigated.Simulation results and observed UVB irradiancies changes in the north-west suburb of Beijing before and after eruptions of Mt. Pinotobo have been compared.Some causes related to the difference batween them have been discussed. |

| Keywords: | ultraviolet irradiancies UVB volcanic aerosol ozone |
