Near‐surface dust flux enrichment in small particles during erosion events

Chemical Characterization of Fine and Coarse Particles in Gosan, Korea during Springtime Dust Events

Particulate matter was collected at Gosan, Korea, a remote location in the East China Sea, from late-March through May, 2007. Two sizes of particles, fine (PM2.5) and coarse (PM10–2.5) modes, were analyzed for chemical composition. Samples were analyzed by mass, elemental and organic carbon, and inorganic ions. Organic molecular markers were also measured using solvent-extraction gas chromatogr...

Investigating Wind Speed Reduction Rate and Aeolian Erosion via Multi-Row Windbreak in Three Dust Storm Events

Introduction: Wind erosion results from desertification in arid and semi-arid regions and is intensified by any decrease in rainfall and vegetation. Sistan region, located in southeastern Iran, has been exposed to severe wind erosion and dust storms for about 23 years as a result of frequent and prolonged drought in the region and desiccation of Hamoun lakes. Therefore, finding appropriate meth...

The concentration, source and deposition flux of ammonium and nitrate in atmospheric particles during dust events at a coastal site in northern China

Asian dust has been reported to carry anthropogenic reactive nitrogen during transport from source areas to the oceans. In this study, we attempted to characterize NH+4 and NO − 3 in atmospheric particles collected at a coastal site in northern China during spring dust events from 2008 to 2011. Based on the mass concentrations of NH+4 and NO−3 in each total suspended particle (TSP) sample, the ...
