Top: 1D nucleation rate log ₁₀J_∗ [cm^-3 s^-1] trajectories ~12 s into the simulation for latitudes θ = 0° (left), 45° (right). The initial, most efficient nucleation regions occur at p_gas< 100 mbar for all atmospheric profiles. Dayside equatorial profiles at φ = 0°, 45° have no nucleation occurring from ~10−100 mbar, where the gas temperature is too high for the nucleation process. The greatest magnitude of nucleation of seed particles is at nightside, mid-high latitude regions at ~1 mbar.
