Rapid radiative transfer model

The '''Rapid Radiative Transfer Model''' (RRTM) is a simulation for the flow of electromagnetic radiation in and out of the Earth.<ref>{{Cite web |title=RRTM Help |url=http://climatemodels.uchicago.edu/rrtm/rrtm.doc.html |access-date=2023-02-22 |website=climatemodels.uchicago.edu}}</ref> It is a validated, correlated k-distribution band model for the calculation of solar and thermal-infrared atmospheric radiative fluxes and heating rates. The '''Rapid Radiative Transfer Model for GCMs''' (RRTM-G) is an accelerated version of RRTM that provides improved efficiency with minimal loss of accuracy for application to general circulation models. The latter divides the solar spectrum into 14 bands within which a total of 112 pseudo-monochromatic calculations are performed, and in the thermal infrared 16 bands are used within which 140 pseudo-monochromatic calculations are performed. RRTM-G is used in a number of general circulation models worldwide, such as that of the European Centre for Medium-Range Weather Forecasts.<ref>{{cite web|title=ECRAD: A new radiation scheme for the IFS|url=https://www.ecmwf.int/en/elibrary/16901-ecrad-new-radiation-scheme-ifs|accessdate=2017-10-22|first=Robin J.|last=Hogan|first2=Alessio|last2=Bozzo}}</ref>
