Size Matters More Than Chemistry for Cloud-Nucleating Ability of Aerosol Particles
Size-resolved cloud condensation nuclei (CCN) spectra measured for various aerosol types at a non-urban site in Germany showed that CCN concentrations are mainly determined by the aerosol number sizeExpand

Role of sulphuric acid, ammonia and galactic cosmic rays in atmospheric aerosol nucleation
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 thatExpand

Measurement of fine particulate and gas-phase species during the New Year's fireworks 2005 in Mainz, Germany
Abstract The chemical composition and chemically resolved size distributions of fine aerosol particles were measured at high time resolution (5 min) with a time-of-flight aerosol mass spectrometerExpand

PTR3: An Instrument for Studying the Lifecycle of Reactive Organic Carbon in the Atmosphere.
We have developed and characterized the novel PTR3, a proton transfer reaction-time-of-flight mass spectrometer (PTR-TOF) using a new gas inlet and an innovative reaction chamber design. The reactionExpand

Quantifying transport into the lowermost stratosphere using simultaneous in-situ measurements of SF 6 and CO 2
The seasonality of transport and mixing of air into the lowermost stratosphere (LMS) is studied using distribu- tions of mean age of air and a mass balance approach, based on in-situ observations ofExpand

Molecular understanding of sulphuric acid–amine particle nucleation in the atmosphere
Nucleation of aerosol particles from trace atmospheric vapours is thought to provide up to half of global cloud condensation nuclei. Aerosols can cause a net cooling of climate by scattering sunlightExpand

Ion-induced nucleation of pure biogenic particles
Atmospheric aerosols and their effect on clouds are thought to be important for anthropogenic radiative forcing of the climate, yet remain poorly understood. Globally, around half of cloudExpand

Laboratory studies of the homogeneous nucleation of iodine oxides
Laboratory experimental results of iodine oxide nucleation are presented. Nucleation was induced following UV photolysis of CF3I or CH2I2 in the presence of excess ozone. Measurements were performedExpand

Enhanced organic mass fraction and decreased hygroscopicity of cloud condensation nuclei (CCN) during new particle formation events
In a forested near-urban location in central Germany, the CCN efficiency of particles smaller than 100 nm decreases significantly during periods of new particle formation. This results in an increaseExpand
