Retrieved temperature, mixing ratios, and haze parameters from all three retrieval set ups. Left: retrieved volume mixing ratios for all three retrieval cases shown at the approximate depth of the haze layer. Right: haze opacity in dashed lines and temperature in solid lines as a function of pressure and altitude. Where available we show the N. A. Teanby et al. (2006) mixing ratios and temperature profile. Despite varying assumptions and haze schemes, all retrievals indicate a haze layer in approximately the same pressure location. Note that the POSEIDON haze location is inferred from the pressure contribution functions and is shown as a shaded region.
