At our distance from the Sun, the intensity of solar radiation is 1370 W/m^2 . As discussed in class and in the textbook, the temperature of the Earth is affected by the greenhouse effect of the atmosphere. This phenomenon describes the effect of absorption of infrared radiation by the surface so as to make the surface temperature of the Earth higher than if it were airless. The average global surface temperature of the Earth is ~288 K. Calculate the surface...
