GG281 Lecture Notes - Boltzmann Equation, Radiant Flux
Document Summary
Fact: significant heat and pressure= hydrogen atoms fuse. Solar flux density= solar luminosity over surface area of sun. Amt of energy emitted from a body is prportional o the 4th power of its temperature. Earth albedo is 0. 3%, therefore absorbs 70% Earth should have a mean temperature, ghg is responsible for maintain heat that we need to survive. Net radiation is tied into albedo because the reflective capacity of a surface influences the amount of radiation reflected back into space. Plancks law, defines the shape of the curve of radiation emission. Wiens law: objects emit of different temperature emit a spectra that peak at different wave lengths,
