Fig. 3: Physical and activation properties of aerosols from different air mass clusters.

a The mean particle number size distribution (dNa/dlogD), b CCN number concentration at a supersaturation of 0.2% in column A (NCCN,0.2%,A), c total aerosol number concentration within a diameter ranging from 18.8 to 685.4 nm (Na), d median diameter of dry particles (Dmedian), and (e) hygroscopicity calculated by NCCN,0.2%,A (κccn,0.2%,A). The error bar represents one standard deviation. The trajectories of the air mass clusters are in Fig. 1.
