Vertical distributions of the major species, after H₂ and He, at four longitudes: substellar meridian, evening limb, antistellar meridian, and morning limb. We show the mole fractions given by the zonal wind thermochemical kinetics model (solid lines), by a one-dimensional model in the vertical direction including thermochemical kinetics and vertical eddy diffusion (dashed lines), and by chemical equilibrium adopting the (p,T) vertical profile at each longitude (dotted lines). Note that abundances above the 10^-4–10^-5 bar level may not be reliable due to the lack of photochemistry in our model and, in the case of the zonal wind model, to a likely change in the circulation pattern.
