Little Things Do Matter Gas-phase sulfuric acid is important during atmospheric particle formation, but the mechanisms by which it forms new particles are unclear. Laboratory studies of the binary nucleation of sulfuric acid with water produce particles at rates that are many orders of magnitude too small to explain the concentration of sulfuric acid particles found in the atmosphere. Sipilä et al. (p. 1243) now show that gas-phase sulfuric acid does, in fact, undergo nucleation in the presence… 

Sulfuric acid nucleation: power dependencies, variation with relative humidity, and effect of bases

Abstract. Nucleation of particles composed of sulfuric acid, water, and nitrogen base molecules was studied using a continuous flow reactor. The particles formed from these vapors were detected with

The role of nitric acid in atmospheric new particle formation.

Within the atmospheric concentration range, nitric acid can enhance the formation rates of sulfuric acid-ammonia clusters, especially at low temperature, low sulfuric Acid concentration and high ammonia concentration, considering the thermodynamic stability combined with the realistic atmospheric concentrations of precursors.

Homogenous nucleation of sulfuric acid and water at close to atmospherically relevant conditions

Abstract. In this study the homogeneous nucleation rates in the system of sulfuric acid and water were measured by using a flow tube technique. The goal was to directly compare particle formation

Total sulfate vs. sulfuric acid monomer concenterations in nucleation studies

Abstract. Sulfuric acid is known to be a key component for atmospheric nucleation. Precise determination of sulfuric-acid concentration is a crucial factor for prediction of nucleation rates and

Contribution of sulfuric acid and oxidized organic compounds to particle formation and growth

Abstract. Lack of knowledge about the mechanisms underlying new particle formation and their subsequent growth is one of the main causes for the large uncertainty in estimating the radiative forcing

Molecular understanding of atmospheric particle formation from sulfuric acid and large oxidized organic molecules

High-resolution mass spectra of ion clusters observed during new particle formation experiments performed at the Cosmics Leaving Outdoor Droplets chamber at the European Organization for Nuclear Research confirm that oxidized organics are involved in both the formation and growth of particles under ambient conditions.

Observation of neutral sulfuric acid-amine containing clusters in laboratory and ambient measurements

Abstract. Recent ab initio calculations showed that amines can enhance atmospheric sulfuric acid-water nucleation more effectively than ammonia, and this prediction has been substantiated in

Mineral dust photochemistry induces nucleation events in the presence of SO2

Evidence is provided for an alternate pathway in which a series of reactions under solar UV light produces first gaseous sulfuric acid as an intermediate product before surface-bound sulfate in the vicinity of dust particles.

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.



Dependence of nucleation rates on sulfuric acid vapor concentration in diverse atmospheric locations

[1] Correlations between concentrations of newly formed particles and sulfuric acid vapor were analyzed for twenty one nucleation events measured in diverse continental and marine atmospheric

Atmospheric sulphuric acid and aerosol formation: implications from atmospheric measurements for nucleation and early growth mechanisms

We have investigated the formation and early growth of atmospheric secondary aerosol particles building on atmospheric measurements. The measurements were part of the QUEST 2 campaign which took

Chemical composition of atmospheric nanoparticles formed from nucleation in Tecamac, Mexico: Evidence for an important role for organic species in nanoparticle growth

We report Thermal Desorption Chemical Ionization Mass Spectrometer (TDCIMS) measurements of the composition of ambient 10–33 nm diameter particles formed from nucleation on 16 March 2006 in Tecamac,

Chemical composition of atmospheric nanoparticles during nucleation events in Atlanta

[1] We report the first direct, in situ measurements of the chemical composition of size-segregated atmospheric nanoparticles in the 6–15 nm diameter range. These measurements were made of ambient

Binary nucleation in acid–water systems. II. Sulfuric acid–water and a comparison with methanesulfonic acid–water

This work presents a systematic investigation of binary nucleation rates for sulfuric acid and water and the effect of temperature on these rates at isothermal, subsaturated conditions. The results

Measurements of gas phase sulfuric and methane sulfonic acid (MSA) have been performed using a relatively new atmospheric pressure selected ion chemical ionization mass spectrometric technique at two

Atmospheric New Particle Formation Enhanced by Organic Acids

The results imply that the interaction between organic and sulfuric acids promotes efficient formation of organic and sulfate aerosols in the polluted atmosphere because of emissions from burning of fossil fuels, which strongly affect human health and global climate.

Laboratory‐measured nucleation rates of sulfuric acid and water binary homogeneous nucleation from the SO2 + OH reaction

We have measured H2SO4‐H2O nucleation rates (J) at atmospheric pressure, 288 K and 10–55 % relative humidity (RH). H2SO4 was produced from the SO2 + OH → HSO3 reaction and was measured with a
