Abstract : Calculations of the total radiation emerging from planetary atmospheres optically thicker than those of the earth. For Rayleigh scattering and Lambert reflectivity, the flux is determined for a wide range of solar elevations, ground reflectivities, and optical depths. For very large surface reflectivities there is more radiation downward onto a planet at the bottom of a thick atmosphere than is received at the top because the radiation that does penetrate undergoes multiple reflection. The total radiation absorbed by the surface plus the corresponding diffuse upward radiation always equals the input flow. Bond albedo is determined by numericaly integration. It approaches the value of the ground reflectivity as optical thickness approaches zero, and approaches 1 as it becomes very large. (Author)
