The simple picture also assumes a steady state, but in the real world, the diurnal cycle as well as the seasonal cycle and weather disturbances complicate matters.
Solar heating applies only during daytime. During the night, the atmosphere cools somewhat, but not greatly, because its emissivity is low. Diurnal temperature changes decrease with height in the atmosphere.
Within the region where radiative effects are important, the description given by the idealized greenhouse model becomes realistic. It reradiates in all directions, both upwards and downwards; in equilibrium by definition the same amount as it has absorbed.
This results in more warmth below. Increasing the concentration of the gases increases the amount of absorption and reradiation, and thereby further warms the layers and ultimately the surface below.
Greenhouse gases Main article: Greenhouse gas By their percentage contribution to the greenhouse effect on Earth the four major gases are:   Atmospheric gases only absorb some wavelengths of energy but are transparent to others.
The absorption patterns of water vapor blue peaks and carbon dioxide pink peaks overlap in some wavelengths.
Carbon dioxide is not as strong a greenhouse gas as water vapor, but it absorbs energy in longer wavelengths 12—15 micrometers that water vapor does not, partially closing the "window" through which heat radiated by the surface would normally escape to space.Chess Hockey Volleyball.
