Evolution of the most abundant oxygen-bearing species for the three test streamlines. The solid lines represent the gas phase of each species, while the dashed lines represent the ice species. CH₂O₂ represents the most abundant organic species in the CPD. We note the change in y-axis range between the top and bottom rows. For water and CH₂O₂ the opacity of the line for t > 40 orbits is slowly reduced to better see the other lines on the plot.
