摘要
本文讨论了利用自动太阳光谱仪测量地面的紫外辐射光谱,并进一步计算了NO_2的光分解系数.光谱测量范围为310—375nm.测量结果表明,在北京地区秋季NO_2的光解系数变化在(1—4)×10^(-3)S^(-1),有明显的日变化.
We measured UV radiation spectrum reaching the ground by the Automatic Solar Spectrophotometer, and calculated NO2 photolysis rate further. The range of spectrum varies from 310 nm to 375 nm. The results show that NO2. photolysis rate varies obviously everyday within the range from 1×10-3s-1 to 4×10-3s-1 in the autumn of Beijing .
