T(z) corresponding to four models presented in this work: average granule (top left; solid blue), average intergranule (top right; solid red), average dark magnetic elements (bottom left; solid green), and average quiet Sun (bottom right; solid black). Standard deviation from the mean values are indicated by the vertical colored lines. The vertical black dashed lines show the location of the τ_c = 1 level in each of these models. Dashed and dotted color lines represent well-known, one-dimensional semi-empirical models for similar solar structures. The z scale in these models has been shifted so that the τ_c = 1 coincides with that of the models introduced in this work.
