RISInfrared Radiation Parameterizations in Numerical Climate Models
Publisher: American Meteorological Society
Abstract: Parameterizations for infrared radiation (IR) in clear atmosphere can be made fast and accurate by grouping spectral regions with similar radiative properties, and by separating the low pressure region of the atmosphere ...
Infrared Radiation Parameterizations for the Minor CO2 Bands and for Several CFC Bands in the Window Region
Publisher: American Meteorological Society
Abstract: Fast and accurate parameterizations have been developed for the transmission functions of the CO2 9.4- and 10.4-?m bands, as well as the CFC-11, CFC-12, and CFC-22 bands located in the 8-12-?m region. The parameterizations ...
