Sub-10 nm particle growth by vapor condensation – effects of vapor molecule size and particle thermal speed
Sub-10 nm particle vapor condensation vapor molecule size particle thermal speed
2010/10/18
The growth of freshly formed nanoparticles has been investigated. A new analytical expression based on a recently developed exact solution for the condensational growth rate has been derived. Based on...
Aerosol fluxes and particle growth above managed grassland
Aerosol fluxes particle growth managed grassland
2009/8/11
Particle deposition velocities (11–3000 nm diameter) measured above grassland by eddy covariance during the EU GRAMINAE experiment in June 2000 averaged 0.24 and 0.03 mm s−1 to long (0.75 m) and...
The potential contribution of organic salts to new particle growth
potential contribution organic salts new particle growth
2009/5/7
Field and lab measurements suggest that low-molecular weight (MW) organic acids and bases exist in accumulation and nucleation mode particles, despite their relatively high pure-liquid vapor pressures...
Sulphuric acid closure and contribution to nucleation mode particle growth
Sulphuric acid closure nucleation mode particle growth
2009/2/8
Sulphuric acid concentrations were measured and calculated based on pseudo steady state model with corresponding measurements of CO, NOx, O3, SO2, methane and non-methane hydrocarbon (NMHC) concentrat...
An inverse modeling procedure to determine particle growth and nucleation rates from measured aerosol size distributions
inverse modeling procedure nucleation rates aerosol size distributions
2009/1/13
Classical nucleation theory is unable to explain the ubiquity of nucleation events observed in the atmosphere. This shows a need for an empirical determination of the nucleation rate. Here we present ...
Size and composition measurements of background aerosol and new particle growth in a Finnish forest during QUEST 2 using an Aerodyne Aerosol Mass Spectrometer

2008/12/31
The study of the growth of nucleation-mode particles is important, as this prevents their loss through diffusion and allows them to reach sizes where they may become effective cloud condensation nucle...
