摘要
本文报道成都地区天空光光谱的测量与分析。测量了不同方位不同倾角的天空光谱,测量结果表明,同一天中天空光光谱分布基本保持不变,不同时段,不同方位和不同倾角的天空光光谱强度不同。与天顶角为零的天空光谱(天顶光谱)比较,不同方位和不同倾角的天空光谱中包含了大气吸收的有用信息,可用于大气污染状况的研究与分析。
Sky - light spectra with different azimythal and different obliquity were measured and analyzed in Chengdu area. The results indicate that the distribution of sky- light spectra primarily retained the same in a day; but the intensities of sky- light spectral vary with different period of time, different obliquity and different azimythal. Compare with spectra of zenith - light spectra （0° zenith angle）, the sky - light spectra include the available information of the atmosphere absorption which can be used for study and analysis of atmosphere pollution status.
