Auringonsäteilyyn

Auringonsäteilyyn refers to the electromagnetic radiation emitted by the Sun. This radiation travels through space and reaches the Earth's atmosphere and surface. The spectrum of solar radiation includes ultraviolet (UV) rays, visible light, and infrared (IR) radiation.

Upon reaching Earth, a portion of the solar radiation is reflected back into space by clouds, atmospheric particles, and the Earth's surface. The remaining radiation is absorbed by the atmosphere and the surface, contributing to the Earth's energy balance and temperature.

Visible light is the part of the spectrum that humans can see, enabling vision and playing a crucial role in photosynthesis for plants. Ultraviolet radiation, though invisible, has significant biological effects, including vitamin D production in the skin and sunburn. Excessive UV exposure can also increase the risk of skin cancer. Infrared radiation is perceived as heat and is a major contributor to the warming of the Earth's surface.

The intensity of auringonsäteilyyn varies depending on factors such as latitude, time of day, season, and atmospheric conditions. These variations influence weather patterns, climate, and the availability of solar energy. Understanding auringonsäteilyyn is essential for fields ranging from meteorology and climatology to solar energy technology and human health.
