Figure 3From: On the average temperature of airless spherical bodies and the magnitude of Earth’s atmospheric thermal effectEmergent linear relationship between cos θ and the regolith shortwave absorption term [1 − A ( θ )] cos θ , where θ is the solar incidence angle and A ( θ ) is the surface albedo as a function of θ defined by Eq. ( 6) (see Figure2).Back to article page
