Abstract : This report presents new atmospheric optical data measured by airborne optical and meteorological sensors recorded near Crater Lake, Oregon, during the first day of a three day period in August 1966. Two data gathering descents were made, from 7800 m to 1400 m, and from 8800 m to 2700 m. The times of these descents were 0913 and 0930 and 1045 to 1101, Pacific Daylight Time. Atmospheric beam transmittances were measured also by a ground station located south of Crater Lake at an altitude of 2070 m. Data presented are altitude profiles of heading of aircraft, temperature, relative humidity, equilibrium luminance, horizontal path function, attenuation length, nadir luminances, and downwelling and upwelling illuminances and their ratios.
