Top and middle: temperature model for the two different solutions found in the GCM retrieval with optical absorbers. For visual reasons, the size of the atmosphere has been doubled. The temperature structure in the top represents the one of the first solution, the green one in Fig. 9. In the middle, there is the thermal structure corresponding to the second, violet solution of Fig. 14. Bottom: temperature map (equatorial cut) of WASP-121 b GCM simulation.
