Evolution of the H₂O abundance profile in the stratosphere of Jupiter for y₀ = 1.1 × 10⁻⁷ above a pressure level p₀ = 0.2 mbar (SL9 parameters) and K_zz Model B. These profiles are obtained from the photochemical model and a comparison with the observations. The red dotted abundance profile represents the initial profile of H₂O at the time of the SL9 comet impacts in 1994. Each solid curve represents the abundance profile of H₂O at dates corresponding to Odin observations. The black dashed profile represents the abundance of H₂O that we predict for 2030.
