Globally averaged (solid, filled) and minimum (dashed, empty) temperatures as a function of surface pressure for Gl 581 c (black circles) and HD 85512 b (gray squares). For comparison, the surface temperature of the 1D model for Gl 581 c is also shown (dotted curve). The error bars on the 200 mbar case show the temperatures reached by varying the surface albedo between 0.1 and 0.5.
