Particle number density (n_d [cm⁻³], bottom axis): green solid – mineral particles, green dashed – hydrocarbon haze (short dashed – total number density Σn(a_i) with a_i the size of the individual haze particle; long dashed – surface averaged n_surf as in Eq. (65) in, dash-dot – volume averaged n_Vol surface as in Eq. (66), both in Kawashima & Ikoma 2018). Mean particles size (⟨a⟩ [μm], top axis): mineral particles – brown; hydrocarbon hazes – orange (⟨a⟩ (Eq. (A.3)) – solid lines; (Eq. (A.6)) – dashed lines; (Eq. (A.8)) – dotted lines, as in Eq. (38) in Kawashima & Ikoma 2018 – dash-dot).
