Earth heat balance equation

WebThe largest values of heat flux coincide with mid-ocean ridges, and the smallest values of heat flux occur in stable continental interiors. Earth's internal heat budget is fundamental to the thermal history of the Earth. The flow of heat from Earth's interior to the surface is estimated at 47±2 terawatts (TW) [1] and comes from two main ... WebEquation [7-2] applies to the no-atmosphere case and hence the Earth with no atmosphere has a surface temperature of 255 K. This temperature is the same as the radiating temperature at the top of our Earth with an atmosphere whose absorptivity (and hence emissivity) is 1 at all emitted infrared radiation wavelengths.
