Abstract:
Solar irradiance scattered from the earths atpssphere was measured in the middle ultraviolet from an Air Force satellite launched in July 1962. The radiomelter defined a wavelength region centered at 2550A with a bandpass at half maximum of about 140A. The effecevve field of view was 1.2 x 10 to the -4 sterad. Due to the late afternoon launch, the minimum angle between the sun direction and the local zenith at the satellite during the flight was 49 deg. The radiance values reached a maximum at these positions and decreased as the vehicle moved toward the shadow region. The maximum radiance value measured was 2.0 0.3 x 10 to the -9 wsq cm -sterad-A. No signal was observed when the vehicle passed over the dark side of the earth. The results compare well with recent theoretical calculations and other experimental measurements. Author
