Sunshine Wallpapers

Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light

On Earth, sunlight is filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon

When the direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat

When it is blocked by the clouds or reflects off other objects, it is experienced as diffused light

The World Meteorological Organization uses the term "sunshine duration" to mean the cumulative time during which an area receives direct irradiance from the Sun of at least 120 watts per square meter
