Cloud properties for a MSG model with SiO nucleation, at 1500 K, and log(ɡ) = 4.0. Left: optical depth of the cloud (orange), gas (blue), and total (green) throughout the atmosphere at λ ≈ 1.1 µm (solid curves) and λ ≈ 10.0 µm (dashed curves). The τ = 1.0 level is shown for reference (dash-dotted red line). Middle and right: composition of the cloud particles in units of volume fractions V_s /V_tot (middle) and the relative gas-phase element depletions ${ϵ}_i/{ϵ}_i^0$ (right).
