Composition of the atmospheric gas in chemical equilibrium with respect to the most abundant molecules, atoms, and ions (number density nx [cm−3 ]) from the night- (top) to the dayside (bottom) on WASP-18b. The day- and nightside have very different chemical atmosphere gas compositions. The dayside is dominated by atomic H, the nightside by H2. The next most abundant gas species are CO, H, or H2, depending on (θ, ϕ). C/O is over plotted to visualise where clouds form. C/O remains at its initial (solar) value on the dayside where no clouds are forming, but increases on the nightside. A complete account of all species per element is provided in Appendix A.
