WebBecause the atmosphere emits and absorbs radiation, the surface of the Earth is much warmer than it would be in the absence of an atmosphere. The luminosity of the sun, L0 … Solar luminosity is related to solar irradiance (the solar constant). Solar irradiance is responsible for the orbital forcing that causes the Milankovitch cycles, which determine Earthly glacial cycles. The mean irradiance at the top of the Earth's atmosphere is sometimes known as the solar constant, I☉. … See more The solar luminosity (L☉), is a unit of radiant flux (power emitted in the form of photons) conventionally used by astronomers to measure the luminosity of stars, galaxies and other celestial objects in terms of the output … See more • Sackmann, I.-J.; Boothroyd, A.
