Atmospheric aerosols exert an important influence on climate through their effects on stratiform cloud albedo and lifetime and the invigoration of convective storms. Model calculations suggest that almost half of the global cloud condensation nuclei in the atmospheric boundary layer may originate from the nucleation of aerosols from trace condensable vapours, although the sensitivity of the number of cloud condensation nuclei to changes of nucleation rate may be small. Despite extensive… 
Ion-induced nucleation of pure biogenic particles
Ion-induced nucleation of pure organic particles constitutes a potentially widespread source of aerosol particles in terrestrial environments with low sulfuric acid pollution.
Molecular understanding of sulphuric acid–amine particle nucleation in the atmosphere
The results show that, in regions of the atmosphere near amine sources, both amines and sulphur dioxide should be considered when assessing the impact of anthropogenic activities on particle formation.
Studies on the connections between atmospheric sulphuric acid, new particle formation and cloud condensation nuclei
Atmospheric aerosol particles (small nm to μm sized particles floating in air) are an important part of the atmosphere and the climate system. Aerosols directly scatter sunlight and influence cloud
Impact of a hydrophobic ion on the early stage of atmospheric aerosol formation
It is shown how a hydrophobic pyridinium ion within a water cluster drastically changes the thermalization properties, which will in turn change the corresponding propensity for water cluster growth and facilitate homogeneous nucleation at the early stages of atmospheric aerosol formation.
Increased ionization supports growth of aerosols into cloud condensation nuclei
It is shown that the mass flux of ions to aerosols enhances their growth significantly, with implications for the formation of cloud condensation nuclei.
Global atmospheric particle formation from CERN CLOUD measurements
A global model of aerosol formation is built by using extensive laboratory measurements of rates of nucleation involving sulfuric acid, ammonia, ions, and organic compounds conducted in the CERN CLOUD chamber and shows that nearly all nucleation throughout the present-day atmosphere involves ammonia or biogenic organic compounds.
Oxidation Products of Biogenic Emissions Contribute to Nucleation of Atmospheric Particles
It is shown, in experiments performed with the CLOUD (Cosmics Leaving Outdoor Droplets) chamber at CERN, that sulfuric acid and oxidized organic vapors at atmospheric concentrations reproduce particle nucleation rates observed in the lower atmosphere.
Biogenic particles formed in the Himalaya as an important source of free tropospheric aerosols
Aerosols of biogenic and anthropogenic origin affect the total radiative forcing of global climate. Poor knowledge of the pre-industrial aerosol concentration and composition, in particular of
Mechanisms of Atmospherically Relevant Cluster Growth.
Amines are effective at assisting the formation and initial growth of clusters but become less important as cluster size increases, especially when hydration is considered, as this work shows how experiment and computation can provide important, complementary information to address problems of environmental interest.


Can cosmic rays affect cloud condensation nuclei by altering new particle formation rates?
Although controversial, many observations have suggested that low‐level cloud cover correlates with the cosmic ray flux. Because galactic cosmic rays have likely decreased in intensity over the last
A new source of tropospheric aerosols: Ion‐ion recombination
We propose a new source of aerosol particles in the lower atmosphere that is based on the formation, growth, and recombination of ubiquitous cosmogenically‐generated ions. This mechanism provides a
Atmospheric ion‐induced nucleation of sulfuric acid and water
[1] Field studies show that gas phase nucleation is an important source of new particles in the Earth's atmosphere. However, the mechanism of new particle formation is not known. The predictions of

Although aliphatic amines have been detected in both urban and rural atmospheric aerosols, little is known about the chemistry leading to particle formation or the potential aerosol yields from
The Role of Sulfuric Acid in Atmospheric Nucleation
Measurements of new particles observed immediately after their formation at atmospherically relevant sulfuric acid concentrations suggest that freshly formed particles contain one to two sulfuric Acid molecules, a number consistent with assumptions that are based on atmospheric observations.
Cloud–Aerosol Interactions from the Micro to the Cloud Scale
The effect of suspended particles (aerosol) on clouds and precipitation from the micro to the cloud scale has been well studied through laboratory, in-situ, and remote-sensing data but many

Abstract. Within the project EUCAARI (European Integrated project on Aerosol Cloud Climate and Air Quality interactions), atmospheric nucleation was studied by (i) developing and testing new air ion

These findings indicate that, at typical upper troposphere and lower stratosphere conditions, particles are formed by this nucleation process and grow to measurable sizes with sufficient sun exposure and low preexisting aerosol surface area.
