Variation of methane saturation and particle radius with pressure. (a) Methane saturation in Uranus atmosphere obtained from CMM after several terrestrial days of simulations. (b) Distance traveled by a methane droplet falling from the 1.2-bar level with different initial radii and the saturation conditions illustrated in panel a before its complete evaporation. The distances are computed by integrating Eqs. (2)–(3) and assuming no vertical mixing. (c) Aerosol-2 profiles derived in IRW22.
