Energy balance models (EBM) are simple climate models that try to predict the average surface temperature of the Earth from solar radiation, emission of radiation to outer space, and Earth’s energy absorption and greenhouse effects.


In a steady state, the Earth has an effective temperature corresponding to the amount of radiation it emits, according to the Stefan-Boltzmann law. This effective temperature is not the same as the average surface temperature however, because the surface temperature depends on radiation and absorption effects of the atmosphere and the oceans. Energy balance models try to account for these effects and try to predict the average surface temperature of the Earth accordingly: The temperature is per definitionem the only output of an EBM.

For some outline data, see solar radiation.
