(a) Properties of a vertical slice in the circumplanetary disk at the centrifugal radius, from five pressure scale heights (left) to the midplane (right). Evolution of the abundance of H₂O, NH₃ and CO₂ ice as the parcel of gas and dust sinks to the midplane after accretion in the reset case: (b) in the partial reset case (c) and the inheritance case (d). Solid lines trace the relevant properties and abundances for the low viscosity (t_visc = 10⁴ yr) case and the dashed line describes the high viscosity (tvisc = 10³ yr) case.
