The Earth's surface radiates the net equivalent of 17 percent of incoming solar energy as thermal infrared.

The amount of energy a surface radiates always increases faster than its temperature rises.

The Sun's apparent surface, the photosphere, radiates more actively when there are more sunspots.

The entire rear surface of her body radiated in the heat of the morning sun.

The computer will judge just as rapidly by the infrared light which the surface radiates even in the dark.

The surfaces of these parts are radiating the energy into the bordering rooms.

From the Stefan-Boltzmann law, this surface will radiate 460 watts.

At body temperature, a surface can radiate over 500 watts per square meter.

Matte-black surfaces will radiate much more efficiently than shiny bare metal in the visible spectrum.

The main negative feedback is the energy which the Earth's surface radiates into space as infrared radiation.
