title: Atmospheric properties and reflectances of ocean water and other surfaces for a low sun.
abstract: Measurements of illuminance at sea level, directional luminous reflectances of ocean water and other surfaces, atmospheric beam transmittance, and path luminance for a day with an unobscured, low sun are presented. These data are applicable for visibility calculations for downward paths of sight.
