Total flux πF_n and degree of polarization P_s of starlight with λ = 0.55 μm that is reflected by a cloud covered model planet. The bottom of the clouds is at 1.0 bar, while the cloud top pressure varies. For the horizontally homogeneous planets, the cloud top pressures are as follows: 0.1 bar (red, dotted line), 0.2 bar (green, dashed line), 0.3 bar (blue, dashed-dotted line), 0.4 bar (grey, dashed-triple-dotted line), 0.5 bar (magenta, long-dashed line). The spatially inhomogeneous planet (black, solid line) has a cloud top pressure of 0.1 bar in the zones, and 0.2 bar in the belts.
