Abundance profiles of gases as a fraction of the total elemental reservoir of oxygen, carbon, nitrogen, sulphur, and fluorine. The abundances are calculated with FastChem Cond (Kitzmann et al. 2024), using SONORA Elf Owl temperature structures (shown in the right panel; Mukherjee et al. 2024) that are representative of Y-, T-, L- and late M-type dwarfs. Oxygen and carbon are carried by multiple gaseous molecules (H₂O, CO, and CH₄), which are shown as their separate and summed profiles. The condensation points of important cloud species are indicated as arrowheads for reference.
