Top: 1D mean grain size log ₁₀⟨ a ⟩ [μm] trajectories at latitudes θ = 0° (left), 45° (right). Cloud particles are typically ~0.1 μm from 0.01−1 mbar. Seed particles are present between 1−100 mbar for many profiles. Bottom: zonal mean (left) and meridional mean (right) average grain size log ₁₀⟨ a ⟩ [μm] as a function of pressure. The smallest grains are found on the dayside at pressures 1−100 mbar at the equatorial regions. The grain sizes are typically sub-micron above ~5 bar and micron sizes below this pressure level.
