Reflected light models of WASP-80 b for a variety of cloud species produced with PICASO and VIRGA, considering a Bond albedo of 0.25. The full and dashed lines correspond to models with sedimentation efficiencies fsed of 0.1 and 3, respectively. The models are compared to our measured secondary eclipse spectrum (black and white points, binned by a factor of 2) for wavelengths below 1.6 μm, where the contribution from thermal emission is minimal, as shown by the pink dotted line. The short-wavelength spectrum is best explained by either chromium (Cr), intermediate-sedimentation sodium sulfide (Na2S), potassium chloride (KCl), or low-sedimentation zinc sulfide (ZnS) clouds.
