Hygroscopicity distribution concept for measurement data analysis and modeling of aerosol particle mixing state with regard to hygroscopic growth and CCN activation
This paper presents a general concept and mathematical framework of particle hygroscopicity distribution for the analysis and modeling of aerosol hygroscopic growth and cloud condensation nucleus (CCN) activity. The cumulative distribution function of particle hygroscopicity, H(κ,Dd) is defined as the number fraction of particles with a given dry diameter, Dd, and with an effective hygroscopici...
متن کاملAerosol hygroscopicity and CCN activation kinetics in a boreal forest environment during the 2007 EUCAARI campaign
Measurements of size-resolved cloud condensation nuclei (CCN) concentrations, subsaturated hygroscopic growth, size distribution, and chemical composition were collected from March through May, 2007, in the remote Boreal forests of Hyytiälä, Finland, as part of the European Integrated project on Aerosol Cloud Climate and Air Quality Interactions (EUCAARI) campaign. Hygroscopicity parameter, κ ,...
متن کاملMeasured and modelled cloud condensation nuclei number concentration at the high alpine site Jungfraujoch
Atmospheric aerosol particles are able to act as cloud condensation nuclei (CCN) and are therefore important for the climate and the hydrological cycle, but their properties are not fully understood. Total CCN number concentrations at 10 different supersaturations in the range of SS = 0.12–1.18% were measured in May 2008 at the remote high alpine research station, Jungfraujoch, Switzerland (358...
متن کاملAerosol hygroscopicity and cloud condensation nuclei activity during the ACExp campaign: implications for cloud condensation nuclei parameterization
Aerosol hygroscopicity and cloud condensation nuclei (CCN) activity under background conditions and during pollution events are investigated during the AerosolCCN-Cloud Closure Experiment (ACExp) campaign conducted at Xianghe, China in summer 2013. A gradual increase in size-resolved activation ratio (AR) with particle diameter (Dp) suggests that aerosol particles have different hygroscopicitie...
متن کاملInteractive comment on “CCN activity and organic hygroscopicity of aerosols downwind of an urban region in central Amazonia: Seasonal and diel variations and impact of anthropogenic emissions” by Ryan Thalman et al
Study by Thalman et al. presents results of κCCN and mixing state derived from sizeresolved CCN observations collected during the GoAmazon2014/5 campaign. From κCCN and additinal aerosol chemical composition measurements, the authors then estimate the hygroscopicity of the organic fraction κorg. The results presented in the study, together with those presented by Pöhlker et al (2016) in another...
