infrared radiation

That portion of the electromagnetic spectrum lying between visible light and microwaves.

The wavelength range is approximately between 720 and 1 mm. In meteorology, this range is often further divided into the solar infrared and terrestrial radiation, with the division occurring around 4 μm. Dominant absorbers of infrared radiation include the earth's surface, clouds, water vapor, and carbon dioxide. By Kirchhoff's law, these are also good emitters of infrared radiation.
