Atmospheric Wet and Dry Depositions of Ions over an Urban Location in South-West India
Soil dust Dry deposition Long-range transport Anthropogenic sources Deposition velocity
2016/3/25
Wet deposition (WD) and Dry deposition (DD) samples were collected during a period of 4 year (2006 to 2009), at four
different sites representing different surroundings around Pune city in southwest ...
This review is based on ca. 260 publications, 93 of which included data on the temporal and spatial variation of the concentration of small ions (<1.6 nm in diameter) especially in the lower troposphe...
Bromide and other ions in the snow, firn air, and atmospheric boundary layer at Summit during GSHOX
Bromide and other ions atmospheric boundary layer Summit GSHOX
2010/10/21
Measurements of gas phase soluble bromide in the boundary layer and in firn air, and Br− in aerosol and snow, were made at Summit, Greenland (72.5° N, 38.4° W, 3200 m a.s.l.) as part of a larger...

2010/9/21
A recently developed atmospheric pressure interface mass spectrometer (APi-TOF) measured the negative and positive ambient ion composition at a boreal forest site. As observed in previous studies, the...
Size distributions of dicarboxylic acids, ketoacids, α-dicarbonyls, sugars, WSOC, OC, EC and inorganic ions in atmospheric particles over Northern Japan: implication for long-range transport of Siberian biomass burning and East Asian polluted aerosols
atmospheric particles Northern Japan Siberian biomass burning and East Asian polluted aerosols
2010/8/13
To better understand the size-segregated chemical composition of aged organic aerosols in the western North Pacific rim, day- and night-time aerosol samples were collected in Sapporo, Japan during sum...
Atmospheric deposition of mercury and major ions to the Pensacola (Florida) watershed: spatial, seasonal, and inter-annual variability
mercury major ions the Pensacola (Florida) watershed inter-annual variability
2010/8/13
Atmospheric deposition was measured at three sites in the Pensacola Bay watershed, Florida, between November 2004 and December 2007. Mercury deposition in the Pensacola Bay watershed was similar to th...
Emission of ions and charged soot particles by aircraft engines
Emission of ions charged soot particles aircraft engines
2009/3/10
In this article, a model which examines the formation and evolution of chemiions in an aircraft engine is proposed. This model which includes chemiionisation, electron thermo-emission, electron attach...

2009/3/10
In order to gain a more comprehensive picture on different mechanisms behind atmospheric particle formation, measurement results from QUEST 2-campaign are analyzed with an aid of an aerosol dynamic mo...
The role of transition metal ions on HOx radicals in clouds: a numerical evaluation of its impact on multiphase chemistry
transition metal ions HOx radicals clouds multiphase chemistry
2009/2/20
A new modelling study of the role of transition metal ions on cloud chemistry has been performed. Developments of the Model of Multiphase Cloud Chemistry (M2C2; Leriche et al., 2001) are described, in...
Rocket measurements of positive ions during polar mesosphere winter echo conditions
Rocket measurements positive ions polar mesosphere winter echo conditions
2009/1/21
On 18 January 2005, two small, instrumented rockets were launched from Andøya Rocket Range (69.3° N, 16° E) during conditions with Polar Mesosphere Winter Echoes (PMWE). Each of the rockets was...
Contribution of fungi to primary biogenic aerosols in the atmosphere: wet and dry discharged spores, carbohydrates, and inorganic ions
fungi primary biogenic aerosols discharged spores carbohydrates inorganic ions
2008/12/18
Biogenic aerosols play important roles in atmospheric chemistry physics, the biosphere, climate, and public health. Here, we show that fungi which actively discharge their spores with liquids into the...
