The effect of solar radiation and albedo on temperature
The sun emits solar radiation (lime colored spheres) which travel down to the Earth's surface.
Once solar radiation collides with the Earth's surface, some of the radiation is reflected (white spheres) while another portion is absorbed and then emitted as infrared radiation (referred to as "heat" represented by red spheres).
The portion reflected and absorbed is determined by the albedo of the Earth, set at 30%.
To model that heat is absorbed into the earth and escapes slowly, we will have the heat move up much more slowly than reflected energy.
