Sulphuric acid closure and contribution to nucleation mode particle growth
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) concentrations as well as solar spectral irradiance and particle number concentrations with size distributions. The measurements were performed as a part of the EU project QUEST (Quantification of Aerosol Nu...

متن کاملIon – Induced Nucleation of Sulphuric Acid and Water
The classical ion-induced nucleation theory is applied to study the formation of new aerosol particles in the binary vapor mixture of sulfuric acid and water in the presence of pre-existing aerosol particles and ion source. The results of a case study for the defined steady state conditions (T = 273 K, RH = 50%) show that the total (free molecules + hydrates) number concentrations of sulfuric a...
متن کاملAtmospheric 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 place in spring 2003 in Hyytiälä (Finland). During the campaign numerous aerosol particle formation events occurred of which 15 were accompanied by gaseous sulphuric acid measurements. Our detailed anal...
