Consistency between parameterisations of aerosol hygroscopicity and CCN activity during the RHaMBLe discovery cruise
Results from a measurement study performed in the Tropical Atlantic on board the RHaMBLe Discovery Cruise D319 are presented. Measurements of aerosol composition, hygroscopicity and CCN activity were used to test the ability of a single parameter model to describe water uptake in suband supersaturated conditions. It was found that the magnitude and temporal variability of the sub-saturated wate...
متن کاملHygroscopicity 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 کاملComposition and hygroscopicity of the Los Angeles Aerosol: CalNex
[1] Aircraft-based measurements of aerosol composition, either bulk or single-particle, and both subsaturated and supersaturated hygroscopicity were made in the Los Angeles Basin and its outflows during May 2010 during the CalNex field study. Aerosol composition evolves from source-rich areas in the western Basin to downwind sites in the eastern Basin, evidenced by transition from an external t...
متن کاملMeasurements of size-resolved hygroscopicity in the California coastal zone
Aircraft – based measurements of aerosol hygroscopicity, both in the form of size-resolved, diameter growth factors and in the dependence of particle light scattering on relative humidity, are presented for the marine boundary layer of the southern California coastal zone. The chemical composition of the aerosol is collated with the hygroscop-5 icity data, both to examine the nature of aerosol ...
متن کاملMeasurements of the Aerosol Light-Scattering Coefficient at Ambient and 85% Relative Humidity on the ONR Pelican During ACE-2
Associated with the renewal of funding in 2002, and the successful attainment of several of the studies early goals, the current goals of the study have been modified and now include the interaction of marine aerosols with marine boundary layer (MBL) clouds. New goals include: 1) assessment of the relative impacts of purely meteorological and aerosol factors on cloud albedo, 2) determination of...
