Abstract : The report presents atmospheric optical data collected in the daytime in Germany chiefly with airborne instruments during a field expedition in the spring of 1970. Results from six flights are presented. The data include irradiance, directional reflectance of terrain, total volume scattering coefficients, atmospheric beam transmittance, path radiance, and directional path reflectance. Data for sunlight and overcast conditions were derived for downward-looking paths of sight inclined at seven zenith angles (93, 95, 97, 100, 120, 150, and 180 degrees) from maximum altitudes of 2400 to 5100 meters AGL and lower in four spectral regions, as follows: two narrow band optical filters with mean wavelengths of 478 and 664 nanometers; and two broad band sensitivities, one representing the S-20 multiplier phototube incorporating an ultraviolet rejection filter with a mean wavelength of 532 nanometers, the other representing the photopic response with a mean wavelength 557 nanometers.
