An efficient and accurate correlated‐k parameterization of infrared radiative transfer for the troposphere, stratosphere and mesosphere (TSM) has been developed. A new approach of g‐quadrature, using the delta log(k) method with non‐uniform intervals, was found to be most efficient. Validation against line‐by‐line calculations for 1D and 2D fields are presented. The scheme is efficient enough to be run in TSMGCMs. Copyright © 2001 Royal Meteorological Society.
