Long-term trends of black carbon and sulphate aerosol in the Arctic: changes in atmospheric transport and source region emissions
black carbon sulphate aerosol the Arctic atmospheric transport source region emissions
2010/10/11
To reveal the contribution of different source regions on these trends, we used a cluster analysis of the output of the Lagrangian particle dispersion model FLEXPART run backward in time from the meas...
A three-dimensional model study of methanesulphonic acid to non sea salt sulphate ratio at mid and high-southern latitudes
three-dimensional model methanesulphonic acid mid and high-southern latitudes
2009/12/31
The Antarctic and sub-Antarctic methanesulphonic acid (MSA) to non sea salt sulphate (nssSO4) ratio is simulated with the Laboratoire de Météorologie Dynamique Atmospheric General Circulation Model in...
Equilibrium of sinks and sources of sulphate over Europe: comparison between a six-year simulation and EMEP observations
sulphate Europe EMEP
2009/7/15
Sulphate distributions were simulated with a global chemistry transport model. A chemical scheme describing the sulphur cycle and the parameterisations of the main sinks for sulphate aerosols were inc...
Glyoxal uptake on ammonium sulphate seed aerosol: reaction products and reversibility of uptake under dark and irradiated conditions
Glyoxal ammonium sulphate seed aerosol irradiated conditions
2009/6/2
Chamber studies of glyoxal uptake onto ammonium sulphate aerosol were performed under dark and irradiated conditions to gain further insight into processes controlling glyoxal uptake onto ambient aero...
Analysis of the hygroscopic and volatile properties of ammonium sulphate seeded and unseeded SOA particles
hygroscopic and volatile properties ammonium sulphate SOA particles
2009/3/12
The volatile and hygroscopic properties of ammonium sulphate seeded and unseeded secondary organic aerosol (SOA) derived from the photo-oxidation of atmospherically relevant concentrations of α-pinene...
Atmospheric impact of the 1783–1784 Laki Eruption: Part II Climatic effect of sulphate aerosol
Atmospheric impact Laki Eruption Climatic effect of sulphate aerosol
2009/3/11
The long 1783-1784 eruption of Laki in southern Iceland, was one of the first eruptions to have been linked to an observed climate anomaly, having been held responsible for cold temperatures over much...
DMS atmospheric concentrations and sulphate aerosol indirect radiative forcing: a sensitivity study to the DMS source representation and oxidation
DMS atmospheric concentrations sulphate aerosol radiative forcing
2009/3/10
The global sulphur cycle has been simulated using a general circulation model with a focus on the source and oxidation of atmospheric dimethylsulphide (DMS). The sensitivity of atmospheric DMS to the ...
Phase transitions and hygroscopic growth of aerosol particles containing humic acid and mixtures of humic acid and ammonium sulphate
Phase transitions hygroscopic growth of aerosol particles humic acid ammonium sulphate
2009/1/4
The phase transitions and hygroscopic growth of two humic acid aerosols (Aldrich sodium salt and Leonardite Standard (IHSS)) and their mixtures with ammonium sulphate have been investigated using a co...
