The objective of this research is to quantify the light from the overcast sky using spectroradiometry and digital imaging to measure the photometric, colorimetric, and polarimetric properties of the light with high spectral, spatial, and temporal resolution. These observations, taken under different meteorological conditions, will constitute a better description of the physical characteristics of skylight than hitherto available and thus provide a new standard for evaluating different atmospheric radiative transfer models. Broader impacts of the work include contributing not only to atmospheric optics, but also to the understanding of cloud effects on radiative transfer and climate and to the education of undergraduate students.

本研究的目的是量化的光从阴天使用分光辐射度和数字成像测量的光度，色度和偏振特性的光与高光谱，空间和时间分辨率。这些观测资料是在不同气象条件下进行的，它们将构成比现有资料更好的描述天空物理特性的资料，从而为评价不同的大气辐射传输模式提供一个新的标准。 这项工作的更广泛的影响不仅包括对大气光学的贡献，而且还包括对云对辐射传输和气候的影响的理解以及对本科生的教育。
