Fig. 2: Time series of aerosol physical and activation properties and the CCN spectra.

a Time series of daily-mean dry particle number size distribution and (b) dry aerosol number concentration (Na), median diameter (Dmedian), and CCN number concentration (NCCN) at various supersaturation (SS) conditions; c Relationships between NCCN and SS at Yadong and other stations. The error bar represents one standard deviation.
