Scattered light apparent geometric albedo A_g,λ (Eq. (32)) of our HD 189733b simulation output compared to Evans et al. (2013)’s individual HST STIS measurements. The total contribution is indicated by the solid blue line; TTHG cloud particle scattering by the dashed orange line; Rayleigh cloud particle scattering by the teal dash-dotted line; H₂ Rayleigh scattering by the brown solid line. Left (0.29−0.6 μm): the Rayleigh and TTHG model is generally consistent with the B band HST STIS measurements, but does not predict the low albedo of the V band. Right (0.29−5 μm): extended spectra from 0.3−5 μm, showing the convolved B band and V band measurements from Evans et al. (2013). A_g,λ becomes negligible beyond 5 μm.
