Colour and Brightness of the Sky

Nature, 1951
IN a recent flight in a De Havilland ‘Comet’ aircraft, measurements were made of the chromaticity (colour), luminance (brightness) and polarization of the sky as observed at heights of 20,000 and 40,000 ft., and of the colour temperature and illumination of the sun's light at 40,000 ft. The results are briefly reported in this communication.
