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. The Earth Observing System Data and Information System is a key core capability in NASA’s Earth Science Data Systems Program. It provides end ...
Outgoing longwave radiation ( OLR) is the longwave radiation emitted to space from the top of Earth's atmosphere. [1] : 2241 It may also be referred to as emitted terrestrial radiation. Outgoing longwave radiation plays an important role in planetary cooling. Longwave radiation generally spans wavelengths ranging from 3–100 microns (μm).
It is a direct measure of the radiative heating of the surface by the atmosphere. The clear-sky surface downward longwave radiation depends on the vertical profiles of the atmospheric temperature, moisture, and presence of other gases ( Ellingson, 1995; Ellingson et al., 1993; Lee and Ellingson, 2002 ): (8.1)
Other articles where longwave radiation is discussed: atmosphere: Radiation: …emitted from Earth is called long-wave radiation; it falls within the infrared portion of the spectrum and has typical wavelengths of 4 to 30 micrometres (0.0002 to 0.001 inch). Wavelengths of radiation emitted by a body depend on the temperature of the body, as specified by Planck’s radiation law. The…

Feb 19, 2022 · Figure 4.3.1.3 4.3.1. 3: Darker urban surface absorb more heat during the day causing the urban heat island effect. Net shortwave radiation is the difference between incoming and outgoing shortwave radiation expressed as: K*= (S+D) - (S+D)a. During the day, K* is a positive value as incoming always exceeds outgoing shortwave radiation.
Oct 22, 2021 · 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 shortwave radiation ...
