Assume a planet with a one-layer atmosphere and values of solar constant S = 1,000 W/m² and albedo α = 0:25. Let us assume there is some dust in the atmosphere, so that 50 percent of the Sun’s energy is absorbed by the atmosphere and 50 percent by the surface. Draw a diagram like Figure 4.5 to show the fluxes, and calculate the planet’s surface temperature.
