Surface Temperature with Absorption (simple, two-layer atmosphere) Remember: what goes in must come out! OTA So (1 - a) = OTA Layer I 4 OTZ OTH OTZ = 20TH Layer 2 OTH +OTA = 2012 OTZ So (1- a) 4 +OTA = OTA GroundConstants and geophysical values: Assume the radius of the Sun to be 6.96 x 108 meters, and the 'radius' (by this, I mean the distance from the Sun to the Earth's orbit) of the Earth to be 1.5 x 1011 meters. The StefanBoltzmann constant is 5.67 X 10'8Wm'2K'4. The 'solar constant' (for our sun) can be treated as 1370Wm'2. The solar ux at the surface of the sun is 6.4 X 107Wm'2. You can assume the Earth system reects 30% of incident solar radiation. Problem 2 Layers of atmosphere Figure 1 shows a schematic of a simplied 2layer atmosphere.
