In climate science, longwave radiation ( LWR) is electromagnetic thermal radiation emitted by Earth's surface, atmosphere, and clouds. It may also be referred to as terrestrial radiation. This radiation is in the infrared portion of the spectrum, but is distinct from the shortwave (SW) near-infrared radiation found in sunlight. [1] : 2251.
The incoming longwave radiation from the atmosphere is absorbed in the top millimeters, unlike incoming shortwave radiation that penetrates much deeper (Section 5.4.3.2). Thus, the outward longwave radiation is determined by the temperature of the literal surface or skin temperature of the sea, which is less than one millimeter thick.
The Earth's thermal emitted radiation is mostly in the infrared (or longwave) part of the spectrum, where Earth's atmosphere is not transparent. Thus, much of the emission to space is from the higher levels of the atmosphere. The balance between incoming and outgoing energy is called the Earth's radiation budget.
Aug 10, 2016 · Emitted LONGWAVE Radiation. Heat resulting from the absorption of incoming shortwave radiation is emitted as longwave radiation. Radiation from the warmed upper atmosphere, along with a small amount from the Earth's surface, radiates out to space.
Mar 9, 1997 · Longwave radiation is radiation with wavelengths longer than 4 micros. Also referred to as infrared radiation or terrestrial radiation. Definition source: National Aeronautics and Space Administration.
Absorbed energy gets re-radiated the in the form of infrared, also known as longwave radiation. Infrared radiation is invisible to our eyes, but we feel it as heat. In the atmosphere, greenhouse gases and clouds absorb and re-radiate heat, affecting the temperature of our planet. Global Change Infographic.
Oct 22, 2021 · Introduction. The Earth’s climate is closely linked to the flow of energy in and out of the Earth-atmosphere system. At equilibrium, the outgoing longwave radiation (OLR) and the reflected...
