Left panel: the solid lines denote the Na₂S cloud-mass fractions as a function of pressure for the f_sed = 0.01, 0.3, and 1 models, shown in red, blue, and gray, respectively. The dashed lines denote the mass fractions derived from equilibrium chemistry, that is, in the absence of mixing and settling. For a comparison, the four vertical lines denote the three different X_max values used in the homogeneous cloud models. Right panel: mean cloud particle radii derived for the f_sed = 0.01, 0.3, and 1 cloud models. Again for comparison, the vertical dotted line denotes the particle size a = 0.08μm adopted for the homogeneous cloud models.
