Converged structures for the 10 bar desiccated (upper panel) and outgassing (lower panel) O₂-dominated TRAPPIST-1 atmospheres. The 10 bar atmospheres are similar in structure to the 100 bar atmospheres above 10 bar (10⁶ Pa). The desiccated atmospheric structures exhibit a strong temperature inversion in the lower atmosphere due to absorption by O₃ and O₂–O₂. The outgassing atmospheric structures and associated surface temperatures exhibit a continuum from Venus-like hotter atmospheres to colder temperature profiles similar to the desiccated cases.
