Abstract The problem of predicting the radio emission from the quiet Sun for meter and decameter waves may be formulated in terms of a standard radiative transfer problem with conservative scattering. One may therefore avoid the numerical complications involved in using a ray-tracing approach which incorporates a Monte-Carlo routine for representing scattering. The brightness and extent of the radio Sun are calculated for several values of the electron temperature and scattering parameter of Steinberg et al. (1971). It is concluded that the temperature and density model of Newkirk (1967) for solar maximum reasonably represents the observations. However, some observations appear to be inconsistent with scattering models and further observations are needed. It is shown (in Appendix B) that the standard ray-tracing technique incorporating a Monte-Carlo routine for the scattering may be replaced by a diffusion approximation.
