Methane mixing ratio profiles derived from the microphysical model for Uranus atmosphere when methane condensation is included (a) and excluded (b) in the simulations. In all the simulations, we set K_eddy(p ≥ 0.4 bars) = 0.5 m² s⁻¹. For comparison purposes, the profile derived from Voyager 2 data is also displayed. If condensation is not included in the simulations, high supersaturations occur in the troposphere, as shown in panel c, where the red line represents saturation when condensation is included in the simulations. The blue curve represents saturation when condensation is not included in the simulations.
