摘要：

使用太阳光度计测量了华南山区秋冬季节白天的大气透过率，分析结果表明：在10~12月中，测量地点的透过率具有明显的日变化、月变化特征。一般每日最大透过率出现在12:00左右，除去水汽波段936 nm，其余波段表现出10月的透过率较其余两月大，936 nm波段则相反；对于340～1020 nm的垂直透过率，除936 nm外，其余波段12月的垂直透过率明显低于其余两个月的测量值。10:00前的垂直透过率变化起伏较大，12:00后的垂直透过率变化较为平稳；不同月份的大气透过率或垂直透过率在10:00后相差不大，午后的大气透过率或垂直透过率一般要好于午前的结果。测量结果可为该地区的有关光学工程应用提供参考。

Abstract:

The sun photometer was used to measure the diurnal atmospheric transmittance of autumn and winter in a mountainous area of South China. The results show that the transmittance of measurement location has distinctive characteristics of daily and monthly variation. The daily maximal transmittance appears around 12:00. The remaining bands show that the transmittance in October is greater than the other two months excluding water vapor band 936 nm. The band 936 nm has reverse characteristics. The vertical transmittance of the band 936 nm shows calmer variation than those of the remain bands whose vertical transmittance in October and November are obviously greater than the vertical transmittance in December. The vertical transmittance of the whole bands presents more variation before 10:00 and the results after 12:00 show calmer variation. The atmospheric transmittance or vertical transmittance of different months shows less fluctuation after 10:00, and the atmospheric transmittance or vertical transmittance of afternoon are currently greater than those of morning. The results can be used as references for the optical engineerings which are applied in the region.

Key words: atmospheric optics, atmospheric transmittance, vertical transmittance, sun photometer, calibration, probability characteristic
