Consider a location in the tropics where the average flux of solar radiation at the top of the atmosphere is 400 W/m2 . A cloud scatters 50 % of the incident solar radiation back to space, and it has an infrared absorptivity of 1.0. What is the lowest cloud top height for a net positive heating effect on climate? Assume the ground temperature is 30o C and the lapse rate is 6o C per km throughout the troposphere.
