Sky luminance distributions for the upper and lower sky at ground level, 1.52 km and 6.10 km are presented for a clear day with a medium high sun. The directional luminous reflectances of a variety of natural terrains and man-made surfaces measured under a clear sky with a moderately high sun are also presented. These data are applicable for use in visibility calculations and supplement the data presented in an earlier article [S. Q. Duntley, J. I. Gordon, John H. Taylor, C. T. White, A. R. Boileau, J. E. Tyler, R. W. Austin, and J. L. Harris, Appl. Opt. 3, 549 (1964)].
给出了中等高度太阳的晴天时地面、1.52千米和6.10千米高度处天空上下半球的天空亮度分布。还给出了在中等高度太阳的晴空下测量的各种自然地形和人造表面的定向发光反射率。这些数据适用于能见度计算，并补充了早期一篇文章[S. Q. 邓特利、J. I. 戈登、约翰·H. 泰勒、C. T. 怀特、A. R. 博伊洛、J. E. 泰勒、R. W. 奥斯汀和J. L. 哈里斯，《应用光学》3, 549 (1964)]中给出的数据。
