The zero-dimensional model above, using the solar constant and given average earth temperature, determines the effective earth emissivity of long wave radiation emitted to space.
This can be refined in the vertical to a one-dimensional radiative-convective model, which considers two processes of energy transport:
? upwelling and downwelling radiative transfer through atmospheric layers that both absorb and emit infrared radiation upward transport of heat by convection (especially important in the lower troposphere).
The radiative-convective models have advantages over the simple model: they can determine the effects of varying greenhouse gas concentrations on effective emissivity and therefore the surface temperature. But added parameters are needed to determine local emissivity and albedo and address the factors that move energy about the earth.
