You can think of a greenhouse gas as a form of albedo that operates on the infrared radiation emitted by the Earth.

In equilibrium these would be balanced by upward transfer of infrared radiation emitted by the surface, by sensible heat flux (warm air carried upward) and by latent heat flux (i.e. evaporation — moisture carried upward).

So, here is my newbie question: Fig 1 shows earth receiving higher levels of infrared radiations from sun then the infrared radiation emitted by earth.

Actually the judge asked a slightly incorrect question (probably unwise to correct him publicly), the question should be,» What is the molecular difference by which CO2 absorbs infrared radiation emitted from the Earth's surface but oxygen and nitrogen do not?»

ABM: The whole point about the greenhouse gases in a planetary atmosphere is that they absorb the infrared radiation emitted by the surface, and so Kirchhoff's law does not apply.

The greenhouse gases absorb some infrared radiation emitted by the surface of the Earth and in turn radiate the absorbed energy back to the surface.

Inside the greenhouse the visible light is absorbed by the plants and soil and is converted into heat, which is then emitted by the plants and soil in form of infrared radiation.

After the sun heats one side, the surface cools when it rotates into shadow and emits infrared radiation.

Although brown dwarfs have no nuclear fire in their belly, they are hot enough to emit infrared radiation, just like a human body.

Early in their lives, the radiation they emitted was largely blocked by the thick veil of their host nebula, visible only to telescopes at infrared and radio wavelengths.

At the same time the surface and the atmosphere emit infrared radiation back to space, which produces cooling.

The visible solar radiation mostly heats the surface, not the atmosphere, whereas most of the infrared radiation escaping to space is emitted from the upper atmosphere, not the surface.

In this purely radiative case, one can think of the atmosphere as emitting infrared radiation both upwards and downwards.

In 2009, the Spitzer Space Telescope discovered infrared radiation from a ring far beyond all the others encircling Saturn; sunlight heats the ring's dust, which emits its heat at infrared wavelengths.

The cooling mechanism involves the absorption of heat by the haze particles, which then emit infrared radiation, cooling the atmosphere by radiating energy into space.

The material is transparent to the visible sunlight that powers solar cells, but captures and emits thermal radiation, or heat, from infrared rays.

Because LEDs do not emit heat as infrared radiation like incandescent or fluorescent bulbs do, it must be removed from the device by conduction or convection.
