Atmospheric transport model applied to understand the effect of biogenic emissions to secondary atmospheric aerosol in hemiboreal zone

The SILAM model with built–in isoprene and monoterpene emission module from natural sources was run for May to August 2006 in Baltic Sea region. In this study VOCs were advected as passive tracers. Modelled hourly VOC–tracer concentrations were compared with sub–half–micrometre aerosol concentrations, simultaneously measured in Preila (Lithuania), Tahkuse (Estonia), Hyytiälä (southern Finland) ...

Bibliometric analysis of aerosol research in meteorology and atmospheric sciences

A bibliometric method was developed to investigate the aerosol research based on the papers from 1991 to 2009 in Science Citation Index Expanded, the Thomson Reuters. The analysed aspects covered scientific output and citation tracking on the basis of journal patterns; country; institute and author research performances. Improved indicators Peak–Year Citation per Publication and Relative ...

Hydrochemistry and dissolved solute load of meltwater in a catchment of a cold-arid trans-Himalayan region of Ladakh over an entire melting period

The hydrochemical study of meltwater draining from a catchment dominated by snowmelt in a cold-arid trans-Himalayan region of Ladakh, India, was carried out for an entire melting season (May–September) during the year of 2010. Cation concentration in the meltwater shows a consistent trend of Ca > >Mg > Na > K for this period. Carbonate weathering has been identified as the ...

Application of Lagrangian particle dispersion models to air quality assessment in the Trans-Manche region of Nord-Pas-de-Calais (France) and Kent (Great Britain)

In the framework of the cross-border EU INTERREG IIIA activity, the joint Anglo-French project, ATTMA, has been commissioned to study Aerosol Transport in the atmosphere of the Cross-Channel, or 'Trans-Manche' region of Nord-Pas-de-Calais (France) and Kent (Great Britain). The air quality of the region is dominated by the industrial area of Dunkerque, in addition to transportation sources linked ...

Field evaluation of a near–real time elemental monitor and identification of element sources observed at an air monitoring supersite in Korea

Abstract Ambient measurements of elemental species concentrations were made using an online elemental monitor at an air pollution monitoring station in Gwangju, Korea to evaluate the performance of the monitor for near–real time PM2.5 elemental monitoring and identify possible sources of the observed elements. This study also demonstrates the utility of integrating hourly elemental data ...

CFD modelling for atmospheric pollutants/aerosols studies within the complex terrains of urban areas and industrial sites

Computational fluid dynamic (CFD) modelling of pollution dispersion and chemical conversion to aerosol particles in the atmospheric boundary layer (ABL) has been studied. The investigation focused on the numerical modelling above complex orographic terrains of urban areas and industrial sites including the dispersion of toxic substances in the air as a result of accidents. A finite-rate model of ...

Classification of iron oxide aerosols by a single particle soot photometer using supervised machine learning

Abstract. Single particle soot photometers (SP2) use laser-induced incandescence to detect aerosols on a single particle basis. Both refractory black carbon (rBC) and other light absorbing metallic aerosols, including iron oxides (FeOx), have been characterized by the SP2, but single particles cannot be unambiguously identified from their incandescent peak height (a function of particle mass) and ...

Accurate PBL Simulation Helps Model Urban Pollution

Atmospheric transport models benefit from real-time localized data inputs. Deteriorating air quality in urban areas is causing growing concern about public health and climate change. To gain a better understanding of air pollution and greenhouse gas (GHG) emissions, some cities and states are attempting to establish a baseline and collect data over time to track changing conditions. By comparing ...
