Abstract

The scheme of computing the temperature change due to long wave radiation, developed by Manabe and Strickler and incorporated into the general circulation models developed at the Geophysical Fluid Dynamics Laboratory of ESSA, is compared with a group of other numerical schemes for computing radiative temperature change (e.g., the scheme of Rodgers and Walshaw). It is concluded that the GFDL radiation model has the accuracy comparable with other numerical models despite various assumptions adopted.
