Cloud Condensation Nuclei Activity and Hygroscopicity of Fresh and Aged Biomass Burning Particles
Abstract Biomass burning particles are one of the largest aerosol sources worldwide and contribute a significant fraction of the global cloud condensation nuclei (CCN) burden. Chemical aging experiments of sawgrass burning particles took place in a smog chamber by turning on the UV light after HONO...

| 520 | |a Abstract Biomass burning particles are one of the largest aerosol sources worldwide and contribute a significant fraction of the global cloud condensation nuclei (CCN) burden. Chemical aging experiments of sawgrass burning particles took place in a smog chamber by turning on the UV light after HONO or $ H_{2} $$ O_{2} $ injection. The CCN activity and corresponding hygroscopicity of fresh and aged particles were measured. Most of the fresh particles can serve as reasonable CCN, and the average activation diameters at 0.2% supersaturation were 114–125 nm in the experiments. The aging process caused that the mass fraction of organic aerosols decrease and condensed phase nitrate $ NO_{3} $− increase, and also the average atomic oxygen to carbon (O:C) ratios increase, which were the main reasons that the aged particles were more CCN active and hygroscopic. The average activation diameters decreased by 8–15% at 0.2% supersaturation after aging, and hygroscopic parameter κ increased by 30–42%. The chemical aging productions were a little different in experiments, but the CCN property and hygroscopicity change trends were quite similar. | ||

Cloud Condensation Nuclei Activity and Hygroscopicity of Fresh and Aged Biomass Burning Particles |
| abstract |
Abstract Biomass burning particles are one of the largest aerosol sources worldwide and contribute a significant fraction of the global cloud condensation nuclei (CCN) burden. Chemical aging experiments of sawgrass burning particles took place in a smog chamber by turning on the UV light after HONO or $ H_{2} $$ O_{2} $ injection. The CCN activity and corresponding hygroscopicity of fresh and aged particles were measured. Most of the fresh particles can serve as reasonable CCN, and the average activation diameters at 0.2% supersaturation were 114–125 nm in the experiments. The aging process caused that the mass fraction of organic aerosols decrease and condensed phase nitrate $ NO_{3} $− increase, and also the average atomic oxygen to carbon (O:C) ratios increase, which were the main reasons that the aged particles were more CCN active and hygroscopic. The average activation diameters decreased by 8–15% at 0.2% supersaturation after aging, and hygroscopic parameter κ increased by 30–42%. The chemical aging productions were a little different in experiments, but the CCN property and hygroscopicity change trends were quite similar. © The Author(s) 2018 |
