How much solar radiation is absorbed
WebSolar radiation contains a considerable amount of ultraviolet radiation, of which especially the short wavelength part below 315 nm is considered to be harmful to life on earth. The range between 280 and 315 nm is designated as UV-B radiation. The stratospheric ozone layer acts as a very efficient natural filter for UV-B radiation. WebJul 28, 2024 · About 30% of the solar energy that reaches Earth is reflected back into space. The rest is absorbed into Earth’s atmosphere. The radiation warms the Earth’s surface, and the surface radiates some of the energy back out in the form of infrared waves.
