Global distribution of mean cloud particle sizes ⟨a⟩ in micronson HAT-P-7b. The color coding is the same as in Fig. 3: the day-side profiles are shown in red, the night-side profiles in blue, the black dot-dashed line is the anti-stellar point (ϕ, θ) = (180^deg, 0^deg). Top left: 1D structures as function of (p_gas) [bar] of the probed 97 profiles. Top right: global 2D map of mean particle size shows that sub-micron cloud particle dominates the night-side atmosphere at p_gas = 10⁻² bar. Bottom left: 2D cut through the equatorial plane. Bottom right: 2D cut along the terminator. The slice plots’ cut of is at ⟨a⟩ = 10⁻⁵ (μm). The dashed green lines indicate where these two slice plots overlap. For the viewing geometry of the slice plots in the bottom row,please see Fig. A.2.
