Our radiative-convective (RC) model captures the basic dependency of surface temperature on τLW and joins previous asymptotic limits. Top: Average dayside surface temperatures of many GCM simulations (N = 251). Bottom: Average nightside surface temperatures. Dashed and dotted curves show previously derived asymptotic scalings in the optically thick (τLW ≫ 1, Pierrehumbert 2011b) and optically thin limits (τLW ≪ 1, Wordsworth 2015). The solid curve shows the RC model (Section 3). While the RC model closely matches the GCM dayside temperatures, it does not account for the wide spread in nightside temperatures. All shown simulations use n = 2 and (R, cp ) = (R, cp)N2.
