Sentences with phrase «radiative emission reaches»
In this explanation what is changing is the altitude at which emission occurs, and at higher levels it is colder, so this level needs to warm up to maintain the radiative balance; what would happen once the altitude of radiative emission reaches above the tropopause?

RCP4.5 was updated from earlier GCAM scenarios to incorporate historical emissions and land cover information common to the RCP process and follows a cost - minimizing pathway to reach the target radiative forcing.
In order to reach such radiative forcing levels, greenhouse gas emissions (and indirectly emissions of air pollutants) are reduced substantially, over time (Van Vuuren et al. 2007a).
whereF is radiant - energy flux at the emitting surface; εis emissivity, set at 1 for a blackbody that absorbs and emits all irradiance reaching its emitting surface (by Kirchhoff's law of radiative transfer, absorption and emission are equal and simultaneous), 0 for a whitebody that reflects all irradiance, and (0, 1) for a graybody that partly absorbs / emits and partly reflects; and σ ≈ 5.67 x 10 — 8 is the Stefan - Boltzmann constant.
