Webthe spectrum of the sun contains absorption lines due to Earth's atmosphere as well as the Sun's outer atmosphere. The continuous spectrum of light from a hot star, after passing through a cool gas cloud shows absorption features where light has been absorbed by the atoms of the cool gas. WebZenith angle (θz) is the angle between the sun's rays and a line perpendicular to the Earth's surface. We calculate it using the latitude (ϕ), declination angle (δ), and hour angle (ω). At solar noon, the hour angle is 0. Incoming TOA solar radiative flux (S0) represents the solar energy received at the top of the Earth's atmosphere. flys maschineThe solar constant (GSC) is a flux density measuring mean solar electromagnetic radiation (total solar irradiance) per unit area.

WebProminences are dense clouds of material suspended above the surface of the Sun by loops of magnetic field. Prominences and filaments are actually the same things except that prominences are seen projecting out above the limb, or edge, of the Sun. Both filaments and prominences can remain in a quiet or quiescent state for days or weeks. WebSolar flux just outside Earth's atmosphere is referred to as the “solar constant” and has a value of approximately 1373 W m − 2. Reflectance, scattering, and absorption of light in the atmosphere can reduce this amount by 15–80% before reaching Earth's surface.

WebBecause the Sun (or any star) is a sphere of radius R, we state it has a surface: A = 4 π R2. With the Sun's radius R = 6,96 × 108m, we can compute its surface temperature T: There is also another way to get the value of T by using Wien's law: λmaxT = b where λmaxis the most intensive wavelength, and b the Wien constant (b = 2,90 × 10-3mK).
