[From sun to earth].
Sun emits a vast array of electromagnetic radiations. After a long but fast journey, the spectrum of visible and ultraviolet light, and infrared radiations reaches the furthermost boundaries of the Earth. Only a fraction of them reaches the biosphere. Photogeoclimatology primarily depends on this energy and is modulated by the latitude, soil relief, seasons and nycthemeral cycle.
