Vertical volume mixing ratios of CO, CO₂, H₂, and H₂O for the 1-bar atmosphere scenario of GJ 1132b with two end-member oxygen fugacities (IW-3 and IW+3). The initial atmospheric composition is set by the outgassing calculation. We consider fo₂ = IW-3 and A_c = 10⁻² for the low oxygen fugacity end-member (top panel) and fo₂ = IW+3 and A_c = 10⁻⁶ for the high oxygen fugacity end-member (bottom panel). Different mixing efficiencies are shown (eddy coefficient K_zz) affecting the molecular abundances at the quench point (e.g., CO₂/CO). The pressure-temperature profiles of both scenarios are shown in Fig. 5 (top panels).
