Equatorial cut of the temperature and water abundance for the 8 GCM simulations with optical absorbers (TiO and VO). The equilibrium temperature of the planet (ranging from 1400 to 2100 K) is specified. From the center outward, the five solid black lines are the 1.434 × 10⁷, 10³, 1, 10⁻², and 10⁻⁴ Pa pressure levels. The hotter the equilibrium temperature, the larger the day-night thermal and chemical dichotomy. Water is completely dissociated below 10³ Pa on the dayside for the hottest simulations.
