Calculation of ion contribution to growth. a The average relative electrostatic enhancement 4(β ±0/β 00)(N 0/N tot) between ions and aerosols of diameter d (solid line). The dotted line is (β ±0/β 00), and the dashed line is (N 0/N tot). b The relative size of the ion condensation, Γ (Eq. (6)) in %, in an atmosphere with a condensible gas concentration of 1 × 106 molecules cm−3 as a function of aerosol diameter d and ionization rate q (left hand axis) or ion density (right hand axis). The contour lines show the relative size of the growth due to ion condensation in % of the usual condensation growth. The mass ratio (m ion/m 0) is set to 2.25, and the mass of the neutral molecule is set to 100 AMU
