The heat energy that is emitted from all solids, liquids, and gases. In the context of the greenhouse issue, the term refers to the heat energy emitted by the Earth's surface and its atmosphere. Greenhouse gases strongly absorb this radiation in the Earth's atmosphere, and radiate some back towards the surface, creating the greenhouse effect. See radiation, greenhouse effect, enhanced greenhouse effect, global warming.

Radiation emitted by the Earthâ€™s surface, the atmosphere, and clouds. It is also known as terrestrial or long-wave radiation. Infrared radiation has a distinctive range of wavelengths (â€œspectrumâ€) longer than the wavelength of the red color in the visible part of the spectrum. In lay term also called heat radiation.

Long wavelength rays, sometimes called "heat waves". Half of the sun's energy is infrared, IR is stronger at high altitudes. Electric heaters, house radiators, and ordinary light bulbs also emit infrared energy. The rays cause the skin to feel hot and may contribute to the discomfort caused by exposure to bright light.
Electromagnetic radiation lying in the wavelength interval from 0.7 5m to 1000 5m (micrometers). Its lower limit is bounded by visible radiation, and its upper limit by microwave radiation. Most of the energy emitted by the Earth and its atmosphere is at infrared wavelengths. Infrared radiation is generated almost entirely by large-scale intramolecular processes. The tri-atomic gases, such as water vapor, carbon dioxide, and ozone, absorb infrared radiation and play important roles in the propagation of infrared radiation in the atmosphere. Source: EPO.

In meteorology, this range is often further divided into the solar infrared and terrestrial radiation, with the division occurring around 4 Î¼m.
