Blackbody reflective thermometer
WebS, the irradiance and hence the radiative equilibrium temperature at the earth surface is increased by the presence of the atmosphere. With a L = .8 and a S = .1 and E = 241 Wm-2, Stefans Law yields a blackbody temperature at the surface of 286 K, in contrast to the 255 K it would be if the atmospheric absorptance was independent of wavelength ... WebSep 1, 2024 · For any temperature and wavelength, an ideal standard blackbody radiant source could completely absorb all radiation incident upon it, and at the same time it emits all the energy that it absorbs. That is to say, ε λ = 1, while the ideal standard blackbody radiant source does not exit. Thus, People pay more attention for the standard radiant ...
