Extended Data Figure 4: Relative humidity and radiative budget for an idealized, cloud-free aquaplanet.
From: Increased insolation threshold for runaway greenhouse processes on Earth-like planets
a, Annually and zonally averaged relative humidity in a latitude–altitude plane. b, Distributions of absorbed (grey dashed) and emitted (grey dotted) flux and surface temperature (solid black) with latitude (annually and zonally averaged). The red line is the asymptotic-limit infrared flux for a saturated atmosphere. Results are shown for the case with insolation 375 W m−2.
