Abstract:

Theoretically derived values of the directional intensity of radiation emerging from both the top and the bottom of a Rayleigh scattering atmosphere are presented graphically. The model assumes a plane-parallel atmosphere illuminated by the sun, with either a completely absorbing planetary surface or Lambert ground reflection. By using Mullikins and Sekeras recent modification of Chandrasekhars radiative-transfer theory, the intensities were obtained for much larger values of the optical thickness of the atmosphere than was previously possible. These intensities are given for a wide range of optical thicknesses, solar zenith angles, and directions of emergence. Author
