Abstract
The interpretation of solar granulation is discussed in terms of the equation of radiative transfer. This is solved for non-uniform two-dimensional media in the absence of radiative equilibrium. The solution is obtained as a functional relation for the attenuation coefficient κ in terms of the total intensity J and the emission function ∊ , and estimates of some of the parameters of simple models are made by fitting mean values of J and κ to tabulated values of Sykes (4) and Plaskett (3). Typical data concerning the horizontal variations in intensity at normal emergence are discussed in terms of the remaining parameters of the models, and the need is indicated for similar information at other angles of emergence.Keywords
