Temperature (top left), specific humidity (top right), relative humidity (bottom left), and area cloud fraction (bottom right) horizontally averaged over the dayside (orange) and nightside (grey) hemispheres, plotted against σ (pressure divided by surface pressure). These are shown for all three simulations: T1:T1e (solid line), ProC:T1e (dashed line), and Sun:T1e (dotted line). The top left panel also includes the hemisphere-averaged surface temperatures from Table 3 as a filled circle for T1:T1e, a filled cross for ProC:T1e, and a filled star for Sun:T1e.
