Fig. 1

Energy from the visible sunlight absorbed by the planet's surface raising the temperature of the soil below as the heat is transmitted to lower levels. The air above is also warmed through the contact with the hot surface skin, which also emits energy to space as infrared radiation.

The temperature of the surface skin of the earth (blue) and of the air at 1.2 m above the ground (red) over 24 h. The air is assumed to have a thermal conductivity of 0.03 W m−1 K−1 and a thermal capacitance of 1.006 kJ Kg−1 K−1.For a maximum solar intensity of: a – 200 Wm−2, b – 400 Wm−2, c – 600 Wm−2, d – 800 Wm−2, e – 1000 Wm−2, f – 1200 Wm−2, g – 1500 Wm−2 and h – 2000 Wm−2.
