> From the previous pictures in pages 4, 5 and 6, we know that the temperature
of a location is generally influenced by three factors:
> How concentrated of the sun ray will be reached to that area.
> The thickness of the atmosphere that the solar rays must pass through.
> The value of albedo of the material that located in that area.

4.1.2.3 Earth's Energy Budget
> Rnet = (Kin - Kout) + (Lin – Lou)
Rnt = net radiation, K = shortwave radiation, L = longwave radiation
Solar energy derived from the sun will be received by the earth surface and it
will modify both short and long wave radiation in reflection.

Earth surfaces that absorb a lot of energy (low albedo) tend to be warmer
(emit more long wave radiation)
