WebThe Stefan-Boltzman Law determines the energy flux, or W per unit area, emitted by the planet. On average, the planet emits radiation over its entire surface, which we can assume is a sphere (4pr2). To determine the total energy emitted by the planet, we simply multiply the Stefan-Boltzman energy flux by the planetary surface area: sT44pr2 WebThe radiosity of an opaque, gray and diffuse surface is given by = +, = + (), where ε is the emissivity of that surface;; σ is the Stefan–Boltzmann constant;; T is the temperature of that surface;; E e is the irradiance of that surface.; Normally, E e is the unknown variable and will depend on the surrounding surfaces. So, if some surface i is being hit by radiation from …

"There are several measured types of solar irradiance. • Total Solar Irradiance (TSI) is a measure of the solar power over all wavelengths per unit area incident on the Earth's upper atmosphere. It is measured perpendicular to the incoming sunlight. The solar constant is a conventional measure of mean TSI at a distance of one astronomical unit (AU). " - Total radiating surface

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 ... Web(Hint: remember the intensity of the longwave earth radiation will be a function of the absolute temperature of the radiating surface from which it is emitted). Total net radiation. The net radiation is the difference between the radiation coming into the Earth from the sun and the energy radiated by the Earth to space.
