Cloud condensation nucleus activity of secondary organic aerosol particles mixed with sulfate
[1] The cloud condensation nucleus (CCN) activity of organic-sulfate particles was investigated using a steadystate environmental chamber. The organic component consisted of secondary organic aerosol (SOA) generated in the dark from 24 ± 2 ppb a-pinene for conditions of 300 ± 5 ppb ozone, 40 ± 2% relative humidity, and 25 ± 1 C, with the organic mass loading in the chamber ranging from 23 to 37...

متن کاملSea spray aerosol as a unique source of ice nucleating particles.
Ice nucleating particles (INPs) are vital for ice initiation in, and precipitation from, mixed-phase clouds. A source of INPs from oceans within sea spray aerosol (SSA) emissions has been suggested in previous studies but remained unconfirmed. Here, we show that INPs are emitted using real wave breaking in a laboratory flume to produce SSA. The number concentrations of INPs from laboratory-gene...
متن کاملExperimental determination of chemical diffusion within secondary organic aerosol particles.
Formation, properties, transformations, and temporal evolution of secondary organic aerosol (SOA) particles depend strongly on SOA phase. Recent experimental evidence from both our group and several others indicates that, in contrast to common models' assumptions, SOA constituents do not form a low-viscosity, well-mixed solution, yielding instead a semisolid phase with high, but undetermined, v...
متن کاملAtmospheric Ice-Nucleating Particles in the Dusty Tropical Atlantic
Desert dust is one of the most important atmospheric ice-nucleating aerosol species around the globe. However, there have been very few measurements of ice-nucleating particle (INP) concentrations in dusty air close to desert sources. In this study we report the concentration of INPs in dust laden air over the tropical Atlantic within a few days’ transport of one of the world’s most important a...
