Laboratory study on new particle formation from the reaction OH + SO2: influence of experimental conditions, H2O vapour, NH3 and the amine tert-butylamine on the overall process
Laboratory study new particle formation the reaction OH + SO2 H2O vapour NH3 the amine tert-butylamine the overall process
2010/8/16
Nucleation experiments starting from the reaction of OH radicals with SO2 have been performed in the IfT-LFT flow tube under atmospheric conditions at 293±0.5 K for a relative humidity of 13–61%. The ...
Observations of the 2008 Kasatochi volcanic SO2 plume by CARIBIC aircraft DOAS and the GOME-2 satellite
the 2008 Kasatochi volcanic SO2 plume CARIBIC aircraft DOAS the GOME-2 satellite
2010/8/13
The 2008 Kasatochi volcanic eruption emitted ≈1.5–2.5 Tg SO2 into the upper troposphere and lower stratosphere. Parts of the main volcanic plume (gases and particles) reached central Europe a week aft...
One conceivable mechanism of UV-light induced SO2 Oxidation to H2SO4
One conceivable mechanism of UV-light SO2 Oxidation to H2SO4
2010/8/12
The electron-excited chemistry of sulfur dioxide oxidation induced by UV irradiation of air with trace O3 and SO2 is considered. The importance of this mechanism is evaluated based on recent laborator...
Formaldehyde and its relation to CO,PAN,and SO2 in the Houston-Galveston airshed
Formaldehyde CO PAN SO2 Houston-Galveston airshed
2010/3/16
The Houston-Galveston Airshed (HGA) is one of the major metropolitan areas in the US that is classified as a nonattainment area of federal ozone standards. Formaldehyde (HCHO) is a key species in unde...
Hit from both sides: tracking industrial and volcanic plumes in Mexico City with surface measurements and OMI SO2 retrievals during the MILAGRO field campaign
tracking industrial and volcanic plumes Mexico City surface measurements OMI SO2
2009/12/31
Large sulfur dioxide plumes were measured in the Mexico City Metropolitan Area (MCMA) during the MILAGRO field campaign. This paper seeks to identify the sources of these plumes and the meteorological...
Kinetic modeling of nucleation experiments involving SO2 and OH: new insights into the underlying nucleation mechanisms
Kinetic modeling nucleation experiments SO2 OH underlying nucleation mechanisms
2009/11/9
Nucleation is an important source of atmospheric aerosols which have significant climatic and health implications. Despite intensive theoretical and field studies over the past decades, the dominant n...
Tula industrial complex (Mexico) emissions of SO2 and NO2 during the MCMA 2006 field campaign using a mobile mini-DOAS system
Tula industrial complex emissions Mexico mobile mini-DOAS system
2009/9/11
The Mexico City Metropolitan Area (MCMA) has presented severe pollution problems for many years. There are several point and mobile emission sources inside and outside the MCMA which are known to affe...
East Asian SO2 pollution plume over Europe – Part 2: Evolution and potential impact
East Asian SO2 pollution Europe Evolution potential impact
2009/7/23
We report on the first observation-based case study of an aged East Asian anthropogenic SO2 pollution plume over Europe. Our airborne measurements in that plume detected highly elevated SO2 mole fract...
Exploring atmospheric boundary layer characteristics in a severe SO2 episode in the north-eastern Adriatic
atmospheric boundary layer severe SO2 episode north-eastern Adriatic
2009/7/15
Stable atmospheric conditions are often connected with the occurrence of high pollution episodes especially in urban or industrial areas. In this work we investigate a severe SO2 episode observed on 3...
DRIFTS and Knudsen cell study of the heterogeneous reactivity of SO2 and NO2 on mineral dust
DRIFTS Knudsen cell study heterogeneous reactivity SO2 NO2 mineral dust
2009/3/11
The heterogeneous oxidation of SO2 by NO2 on mineral dust was studied using Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) and a Knudsen cell. This made it possible to characteri...

2009/3/11
A detailed study of the levels, the temporal and diurnal variability of the main compounds involved in the biogenic sulfur cycle was carried out in Crete (Eastern Mediterranean) during the Mediterrane...
Gas-particle interactions above a Dutch heathland:I. Surface exchange fluxes of NH3, SO2, HNO3 and HCl
Gas-particle interactions Dutch heathland NH3 SO2 HNO3
2009/2/27
A field measurement campaign was carried out over a Dutch heathland to investigate the effect of gas-to-particle conversion and ammonium aerosol evaporation on surface/atmosphere fluxes of ammonia and...
The uptake of SO2 onto Saharan mineral dust from the Cape Verde Islands was investigated using a coated wall flow tube coupled to a mass spectrometer. The rate of loss of SO2 to the dust coating was ...
Effects of SO2 oxidation on ambient aerosol growth in water and ethanol vapours
SO2 oxidation ambient aerosol growth water ethanol vapours
2009/2/7
Hygroscopicity (i.e. water vapour affinity) of atmospheric aerosol particles is one of the key factors in defining their impacts on climate. Condensation of sulphuric acid onto less hygroscopic partic...
