Snapshots of the latitudinally (left) or longitudinally (right) averaged T–P profile for two evolved models of Kepler-13Ab (top) and KELT-1b (bottom) at various longitudes or latitudes respectively. These models include radiative forcing, via Newtonian cooling, at all pressures. This cooling is based upon a combination of the equilibrium 1D radiative timescale profile (grey) including the observed day-night temperature difference in the outer atmosphere, and 1D sub-stellar and non-irradiated 1D models in the deep atmosphere. The overall result is a combined Newtonian cooling model with a day-side (at the sub-stellar point) forcing profile that corresponds to the red dashed line and a night-side forcing profile that corresponds to the blue dashed line.
