Differences to the opacity contribution of observable molecular species due to disequilibrium chemical kinetics. The difference metric, , is defined such that a positive difference implies stronger absorption after accounting for disequilibrium chemistry (i.e., p(τ_x (λ) = 1) occurs higher in the atmosphere). Only H₂O, CO, and CO₂ are plotted because these molecules offer the greatest detection prospect in the near-infrared (see Fig. 11). All opacities are plotted at a spectral resolution of R = 1000. Four equatorial regions are considered: (i) the antistellar point, (ii) the morning terminator, (iii) the substellar point, and (iv) the evening terminator.
