Airborne Measurements of Optical Atmospheric Properties in Western Washington.

Abstract

This report presents daytime atmospheric optical data collected chiefly with airborne instruments during a field expedition to western Washington in the summer of 1974. Results from seven flights are presented. The data include the natural irradiance upon horizontal plane surfaces, scalar irradiances, total volume scattering coefficients, atmospheric beam transmittances, path radiances, directional path reflectances, and directional terrain reflectances. Data for daytime conditions ranging from clear skies to completely overcast were derived for downward-looking paths of sight inclined at six zenith angles (95, 100, 105, 150, and 180 degrees) from altitudes of 1200 meters above ground level and lower. All data were measured with a broad band sensitivity representing pseudo-photopic spectral response with a mean wavelength of 557 nanometers. (Author)
