Первый слайд презентации: Solar Radiation or Solar Irradiance
Kalinovskiy Ilya 2nd year, DP28 Teacher: Yurieva A.V
Visible light and infrared radiation reach the surface, warming the surface to livable conditions. The primary source of energy to the Earth is radiant energy from the Sun. This radiant energy is measured and reported as the solar irradiance.
Ultraviolet radiation in the UV-A, B, and C wavelengths is absorbed at higher and higher altitudes. Extreme ultraviolet and soft X-ray radiation is absorbed by the atmosphere above 60 miles.
SDO's investigations are designed to understand the source of the Sun's energy, and how that energy is stored and released by the layers of the Sun's atmosphere. One part of that research is how the changes in the solar irradiance, or photon output, are produced.
Слайд 6: What is Solar Irradiance?
Irradiance is the amount of light energy from one thing hitting a square meter of another each second.
Photons that carry this energy have wavelengths from energetic X-rays and gamma rays to visible light to the infrared and radio. Important spectral irradiance variations are seen in many wavelengths, from the visible and IR to EUV and X-ray.
