Obtained particle size as function of pressure for the cloud models applied to GJ1214b. The intensity of the rain in terms of the volume density of condensates (ρ_c = x_cρ_gas) is indicated by the color bar. Three values of the nuclei production rate are considered (as indicated by color) and results are plotted with and without accounting for coagulation. The diffusivity parameter is fixed at K_zz = 10⁸ cm² s⁻¹. Particle radii are larger in runs that include coagulation.
