  • Atmospheric dispersion of argon-41 from a nuclear research reactor: measurement and modelling of plume geometry and gamma radiation field

    An atmospheric dispersion experiment was conducted using a visible tracer along with the routine releases of 41Ar from the BR1 research reactor in Mol, Belgium. Simultaneous measurements of plume geometry and radiation field from 41Ar decay were performed as well as measurements of the 41Ar source term and the meteorological parameters. ...

  • Aerosol characteristics at a continental urban station in southern India

    Spectral Aerosol Optical Depth (AOD), Black Carbon (BC) mass concentration and Suspended Particulate Matter (SPM) measurements were made at an urban continental location, Bangalore (13°N, 77.6°E), in southern India. These results show that AODs reach a maximum during April (∼0.5) and minimum during December (∼0.2) at 500 nm. BC and SPM showed variations of 0.6-4.2 μg m³ and 120-195 μg m³, ...

  • GAW Regional Station for Atmospheric Research - 2005 Report

    The aim of the JRC-Ispra station is to monitor the concentration of pollutants in the gas phase, the particulate phase and precipitations, as well as aerosol optical parameters, which can be used for assessing the impact of European policies on air pollution and climate change. Measurements are performed in the framework of international monitoring programs like the Co-operative program for ...


  • Modelling of aerosol in the Greater Athens Area, Greece

    Aerosols have recently been defined as a serious atmospheric pollution problem in the Greater Athens Area (GAA). This research is mainly focused on assessing the PM10 concentration levels in the GAA atmosphere through simulations. The model results of the chemical constituents of PM10 are satisfactory comparing to measurements; the discrepancies are attributed to the re-suspended and seaborne ...

  • Elemental composition of airborne aerosols at a traffic site and a suburban site in Hong Kong

    Forty elemental concentrations in different size particles were measured at a roadside site and a suburban site of Hong Kong using a ten-stage MOUDI impactor (Mode 110). Some elements (Cr, Fe, Co, Cu, As and Ba) have clear spatial variability, with ∼100% higher concentrations in roadside atmosphere than in suburban atmosphere, showing obviously vehicle-related sources for those elements. However, ...

  • Airborne chemical elements: correlation between atmospheric levels and lichen content

    Concentrations of As, Cd, Co, Na, Sb, Se and Zn have been measured in atmospheric particulate matter and Parmelia sulcata Taylor transplants at a suburban and industrial area. Levels in particulate matter were found to be much lower than European target values, Californian Acute Inhalation Reference Exposure Levels and Ontario's Ambient Air Quality Criteria. Correlations between elemental content ...

  • Atmospheric lead concentrations near roadways in a suburban part of Istanbul

    In this study, daily aerosol samples of fine (PM2.5) and coarse (PM2.5−10) particles were collected at Buyukcekmece (41°2′35″N, 28°35′25″E), a sub-urban part of Istanbul, Turkey. Sampling area is under the impact of two main transport arteries, namely the Trans European Motorway (TEM) and E5 motorways. Atmospheric lead levels measured in this study were compared with those reported previously ...

  • Towards the simulation of size-resolved aerosol over Europe: model and observations

    Knowledge of the number density and size distribution of atmospheric aerosols in the submicron size range is essential for estimation of the aerosol radiative effects and the health impact of particles. Ultrafine particles (UFP), i.e. particles with diameters <100 nm, have received increased attention in recent years with improved possibilities of measuring them. UFP originate from nucleation, ...

  • WRF evaluation exercise using open sea in situ measurements

    This work regards a model evaluation exercise concerning the WRF meteorological model and in situ measurements collected both over land, at four WMO meteorological stations, and over open sea, by ODAS Italia 1, the only spar buoy in the Mediterranean Sea. In particular, this exercise is finalised to understand the ability of the model to act as meteorological pre–processor to simulate aerosol ...

  • Long-term simulations of particulate matter in Europe on different scales using sequential nesting of a regional model

    A regional model system for the simulation of air quality in Europe (EURAD) has been employed for long-term calculations of atmospheric pollutants on different scales. The model allows sequential nesting. Starting with a domain covering most of Europe, the nesting procedure was used to scale down the simulations to a highly populated and industrialized area, namely NorthRhine-Westphalia (NRW). ...

  • Observation based analysis for the determination of equilibrium time constant between ammonia, acid gases, and fine particles

    Experimental measurements of ammonia, acid gases, and the inorganic components of atmospheric aerosols were made at a commercial hog farm in eastern North Carolina from May 1998 to June 1999 by an annular denuder system (ADS). The ADS consisted of a cyclone separator, one diffusion denuder coated with sodium carbonate, another diffusion denuder with citric acid, and a filter pack containing ...

  • Remote sensing of particular pollution from space: Have we reached the promised land?

    The recent literature on satellite remote sensing of air quality is reviewed. 2009 is the 50th anniversary of the first satellite atmospheric observations. For the first 40 of those years, atmospheric composition measurements, meteorology, and atmospheric structure and dynamics dominated the missions launched. Since 1995, 42 instruments relevant to air quality measurements have been put into ...
