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 [ DuntleyS. Q. GordonJ. I. TaylorJohn H. WhiteC. T. BoileauA. R. TylerJ. E. AustinR. W. HarrisJ. L., Appl. Opt. 3, 549 ( 1964)].
