Venus composition profiles for selected species predicted with our photochemistry model for scenario 1 (PH₃ flux, solid blue line) and scenario 2 (PO flux, solid orange line). The shaded areas show the 99% ranges of the MC runs of scenario 1 (shaded blue) and scenario 2 (shaded orange). For comparison, a range of observations is shown with black lines. We additionally show the observational ranges from Greaves et al. (2020, 2021b) and upper limits of Trompet et al. (2021).
