WebIn RRTM_SW, radiative transfer can be calculated with the discrete-ordinates model (DISORT), or with a faster, though less accurate 2-stream method derived from the collaborative 3ARM radiation model. Figure 1 shows fluxes and heating rates calculated by RRTM using DISORT with 16 streams (left panels). WebIn section 2, RRTM and the CCM3 longwave model are described in greater detail, and the modifications made to RRTM to prepare it for implementation into the GCM are discussed. Single-column comparisons of the radiation models are presented in section 3 for two clear-sky profiles and several cloudy-sky cases. def of oracle
