AB  - During 11-18 September 2014, the size-resolved aerosol Cloud Condensation Nuclei 
      (CCN) activity and mixing state were measured using Cloud Condensation Nuclei 
      Counter (CCNC), Aerosol Particle Mass (APM) and Scanning Mobility Particle Sizer 
      (SMPS). The results showed that aerosols mainly existed as an internal mixture. 
      For 76, 111, 138 and 181 nm particles, black carbon (BC) accounted for 5.4%, 10%, 
      l0.7% and 6.7% of the particle mass, but as high as 51%, 57%, 70% and 59% of the 
      particle number concentrations, respectively, suggesting that BC was a type of 
      important condensation nuclei in the atmosphere and made significant 
      contributions to particle numbers. The occasionally observed external mixtures 
      were mainly present in 111 and 138 nm particles. The critical supersaturation was 
      0.25%, 0.13%, 0.06% and 0.015% for 76, 111, 138 and 181 nm particles, 
      respectively. Precipitation and haze had significant effects on the particle CCN 
      activity. The hygroscopicity parameter K was 0.37, 0.29 and 0.39 in rainy, clear 
      and hazy days, respectively. Particle density and CCN activity were impacted by 
      chemical compositions. Compared with clear days, higher contents of inorganic 
      salts and lower contents of organics were found on hazy days, accompanied by 
      lower particle density and higher CCN activity.
