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...
Particle formation in the Arctic free troposphere during the ASTAR 2004 campaign: a case study on the influence of vertical motion on the binary homogeneous nucleation of H2SO4/H2O
Arctic free troposphere ASTAR 2004 campaign binary homogeneous nucleation of H2SO4/H2O
2010/2/21
During the ASTAR (Arctic Study of Tropospheric Aerosol and Radiation) campaign nucleation mode particles (4 to 13 nm) were quite frequently observed at altitudes below 4000 m. However, in the upper fr...
Gaseous（DMS, MSA, SO2, H2SO4 and DMSO）and particulate（sulfate and methanesulfonate）sulfur species over the northeastern coast of Crete
MSA SO2 H2SO4 DMSO northeastern coast of Crete
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...
A novel model to predict the physical state of atmospheric H2SO4/NH3/H2O aerosol particles
novel model atmospheric H2SO4/NH3/H2O aerosol particles
2009/3/11
The physical state of the tropospheric aerosol is largely unknown despite its importance for cloud formation and for the aerosol's radiative properties. Here we use detailed microphysical laboratory m...
The Hohenpeissenberg aerosol formation experiment（HAFEX）：a long-term study including size-resolved aerosol, H2SO4, OH, and monoterpenes measurements
Hohenpeissenberg aerosol formation experiment HAFEX size-resolved aerosol H2SO4
2009/3/10
Ambient aerosol size distributions (>3 nm) and OH, H2SO4, and terpene concentrations were measured from April 1998 to August 2000 at a rural continental site in southern Germany. New particle formatio...
Impact of H2SO4/H2O coating and ice crystal size on radiative properties of sub-visible cirrus
H2SO4/H2O coating ice crystal size radiative properties sub-visible cirrus
2009/1/16
Recent laboratory experiments showed that at conditions resembling those near the tropopause region, small ice particles can be coated by a liquid H2SO4/H2O over-layer formed after the freezing of dil...
Estimating the NH3:H2SO4 ratio of nucleating clusters in atmospheric conditions using quantum chemical methods
NH3:H2SO4 quantum chemical methods
2008/12/10
We study the ammonia addition reactions of H2SO4·NH3 molecular clusters containing up to four ammonia and two sulfuric acid molecules using the ab initio method RI-MP2 (Resolution of Identity 2nd orde...
SO2 oxidation products other than H2SO4 as a trigger of new particle formation. Part 1: Laboratory investigations
SO2 oxidation products H2SO4
2008/11/25
Mechanistic investigations of atmospheric H2SO4 particle formation have been performed in a laboratory study taking either H2SO4 from a liquid reservoir or using the gas-phase reaction of OH radicals ...
Laboratory studies of H2SO4/H2O binary homogeneous nucleation from the SO2+OH reaction: evaluation of the experimental setup and preliminary results
H2SO4/H2O binary homogeneous nucleation SO2+OH reaction
2008/11/17
Binary homogeneous nucleation (BHN) of sulphuric acid and water (H2SO4/H2O) is one of the most important atmospheric nucleation processes, but laboratory observations of this nucleation process are ve...
