Short summary

We investigate the contribution of grown new particles to N_ccn at a rural mountain site in the North China Plain. The total particle number concentrations (N_cn) observed on 8 new particle formation (NPF) days were higher compared to non-NPF days. The N_ccn at 0.2 % supersaturation (SS) and 0.4 % SS on the NPF days was significantly lower than on non-NPF days. Only one of eight NPF events had detectable net contributions to N_ccn at 0.4 % SS and 1.0 % SS with increased κ values.
