Incoming radiation formula

WebAccording to analyses of stratigraphic distributions of oxidized and reduced mineral deposits, the atmosphere of the early Earth (4 Byr ago) was anoxic near the surface, with the O 2 mixing ratio less than 10, −4, and it is generally accepted that today's oxygen-rich atmosphere is the product of photosynthesis and organic– carbon burial.An anoxic early … WebThe Stefan-Boltzmann equation then gives the energy flux emitted at the sun’s surface. S S = (5.67 × 10 –8 W·m –2 ·K –4 ) (5800 K) 4 = 63 × 10 6 W·m –2. The surface area of a sphere with a radius r is 4πr 2. If r S is the radius of the Sun, the total energy it emits is S S 4πr s2. As the radiation is emitted from this spherical ...
