【摘要】 依据已经建立起来的昆明地区紫外辐射传输方案,计算并讨论了大气中中低云、气溶胶粒子以及不同地理纬度和海拔高度对UV辐照度的影响。研究结果表明,在考虑了大气层中臭氧的吸收和空气分子散射的情况下,UV辐照度随地理纬度的增高和海拔高度的降低均有明显而强烈的改变。云对紫外辐照度有很大的影响,而且低云对UV辐照度的削弱作用大于中云的削弱作用。大气中气溶胶粒子对紫外辐射的影响在UV-A波段和UV-B波段具有不同的表现。更多还原

【Abstract】 Based on the model calculation the surface biologically-active UV irradiance in Kunming area,the influence of clouds with low and middle heights、aerosol、latitude、altitude have been discussed.It has been indicated that with the different input value of latitude and height,the surface UV irradiance of Kunming changes rapidly.And the cloud has an evident influence on the UV irradiance.Furthermore,the model result shows that the aerosol atmosphere can efficiently affect UV-A and UV-B irradiance.更多还原
