Scenario with hazes including heat conduction. Left: simulated temperature profiles on Uranus with the Irwin et al. (2022) haze scenario but no conduction (long-dashed orange line) and with haze and thermospheric conduction with the UC2 flux scenario (dashed green line). Right: same for Neptune (but with the NC1 flux scenario for the dashed green line). The solid blue line is the clear-sky case (Sect. 3) and the black symbols are the observed temperatures described in Fig. 1.
