title: Fast radiative-transfer model based on the correlated k-distribution method for a high-resolution satellite sounder.
abstract: A fast radiative-transfer model for the Atmospheric Infrared Sounder (AIRS) was developed by use of a correlated k-distribution method. Transmittances produced by the correlated k-distribution method are systematically displaced from those produced by a line-by-line method, and empirical correction is possible. A fast radiative model that includes this empirical correction has exhibited practical performance in tests of transmittance and brightness temperature that used an independent set of atmospheric profiles.
