Abstract : The report presents atmospheric optical data collected in the daytime chiefly with airborne instruments during a field expedition to central New Mexico in the Fall 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, 100, 105, 120, 150, and 180 degrees) from altitudes of 4500 meters above ground level and lower in four spectral regions, as follows: three narrow band optical filters with mean wavelengths of 478,664, and 765 nanometers; and one broad band sensitivity representing the photopic response with a mean wavelength of 557 nanometers.
