säteilytasapainolla
Säteilytasapaino refers to the balance of incoming and outgoing radiation for a celestial body, most importantly for Earth. This balance is crucial for maintaining a stable temperature. Solar radiation, primarily in the form of visible light and ultraviolet radiation, is absorbed by the Earth's surface and atmosphere. A portion of this incoming energy is reflected back into space by clouds, ice, and the surface itself, a measure known as albedo. The remaining absorbed energy warms the planet.
Earth then emits energy back into space as thermal infrared radiation. In a state of radiative equilibrium,
The composition of the atmosphere plays a significant role in radiative balance. Greenhouse gases, such as
