Evolution of the H₂O line-to-continuum ratio observed by Odin in the atmosphere of Jupiter (black points). The blue stars represent the results obtained with our K_zz Model B. The green and pink dots correspond to different values of the y₀ parameter with the same model. The red triangles stand for our nominal parameters of y₀ and p₀ and K_zz Model A (profile from Moses et al. 2005). The orange dots depict the results obtained with the vertical profiles of Model A after rescaling their respective column densities to the temporal evolution modeled by Lellouch et al. (2002) with their chemistry-2D transport model.
