Atmospheric mixing ratios for atmospheres with water fractions of 100%, and 0.1% under stellar forcing in the YMDF model and with 400K internal hitting at the bottom boundary (two vertical panels on the left), and 360-days evolution of the mixing ratios of photodissociation-driven species with concentrations above 10⁻⁴ in the uppermost atmospheric layer of these two atmospheric regimes (two horizontal panels on the right).
