Understanding the Influence of Cloud on the Spectral Solar Ultraviolet Radiation

了解云对光谱太阳紫外线辐射的影响。由于某些云层条件，陆地光谱太阳紫外线可能会增强到晴朗天空之上。关于云对太阳紫外线光谱的影响以及由此产生的具有生物破坏性的紫外线，在科学知识方面存在重大差距。该项目将收集跨越12个月的每十分钟的天空条件和光谱紫外线的唯一数据集，以确定：辐照度增加的特定波长；破坏性紫外线增强的量；导致这些增强的云条件，并开发预测能力，以确定云层何时将增强太阳紫外线。

Understanding the Influence of Cloud on the Spectral Solar Ultraviolet Radiation. Terrestrial spectral solar UV may be enhanced above that of clear sky due to certain cloud conditions. There is a major gap in the scientific knowledge of the influence of cloud on the spectral solar UV and resultant biologically damaging UV. This project will collect the only dataset of sky conditions and spectral UV for each ten minute period spanning 12 months to determine: the specific wavelengths with increased irradiances; the amount of enhanced damaging UV; the cloud conditions that cause these enhancements and develop a predictive capability to determine when cloud cover will enhance solar UV.
