Sentences with phrase «on radiative transfer equations»
Jeff, the 1C value for a forcing of 3.7 W / m ^ 2 (the canonical value for doubled CO2 based on radiative transfer equations and spectroscopic data) is derived by differentiating the Stefan - Boltzmann equation that equates flux (F) to a constant (sigma) x the fourth power of temperature.

I would argue that if we use a simple radiative model with a variety of assumptions, no upper atmosphere cooling but only warming will occur with increased CO2 (see # 333), based on the radiative transfer equations and the Second Law of thermodynamics, but when other complexities are introduced, this might change.

The core science, the radiative transfer equations that determine the way increasing CO2 increases the temperatures gradient between the emission altitude and the surface, derived from military research on heat seeking missile and detection systems.
The direct radiative forcing calculation is based on an empiric al equation derived from well - established atmospheric radiative energy transfer models and serves as a first - order proxy for global warming impact.»
But the reason that the models are failing to reproduce what we see that they are based on an approximation of the radiative transfer equation which does not apply to the boundary layer where the ice is melting.
And, there is plenty of empirical data at every level: There is empirical data on the basic absorption lines of the various atmospheric constituents, there is a wealth of empirical data backing up the basic equations of radiative transfer that are applied in calculating the greenhouse effect in just the same way that engineers and scientists use these equations everyday in other calculations, there is empirical spectra looking both up from the surface of the earth and down from satellites.
