Equilibrium Temperature
The planetary equilibrium temperature is a theoretical temperature that the planet would be at when considered simply as if it were a black body being heated only by its parent star. In this model, the presence or absence of an atmosphere (and therefore any greenhouse effect) is not considered, and one treats the theoretical black body temperature as if it came from an idealized surface of the planet.
Other authors use different names for this concept, such as equivalent blackbody temperature of a planet, or the effective radiation emission temperature of the planet. Similar concepts include the global mean temperature, Global radiative equilibrium, global-mean surface air temperature, which includes the effects of Global warming.

Famous quotes containing the words equilibrium and/or temperature:
“They who feel cannot keep their minds in the equilibrium of a pair of scales: fear and hope have no equiponderant weights.”
—Horace Walpole (1717–1797)
“This pond never breaks up so soon as the others in this neighborhood, on account both of its greater depth and its having no stream passing through it to melt or wear away the ice.... It indicates better than any water hereabouts the absolute progress of the season, being least affected by transient changes of temperature. A severe cold of a few days’ duration in March may very much retard the opening of the former ponds, while the temperature of Walden increases almost uninterruptedly.”
—Henry David Thoreau (1817–1862)
