Fig. 15

Dust κext [cm2 g-1] opacity for 5.8 μm interpolated across the globe of HD 189733b assuming latitudinal (north-south) symmetry. Top row: 10-4 bar, 10-3 bar. Middle row: 10-2 bar, 10-1 bar. Bottom row: 1 bar, 10 bar, respectively. We take 5.8 μm as representative of the infrared extinction due to cloud. The sub-stellar point is at φ = 0°, θ = 0°. The maximum extinction efficiency shifts from the dayside of the planet to the nightside with increasing depth. Deep in the atmosphere the most opaque region remains at ~225°...315°longitudes. Note: the colour scale for each plot is different.
