  • Multiple Instruments Work Together for a Better View of Air Quality

    Accurately identifying and quantifying particulate matter (PM) in the atmosphere is key to determining air quality. Researchers are particularly interested in PM that have a diameter of less than 2.5 micrometers because they are believed to contribute to heart and lung disease in humans and animals. These tiny particles are invisible to the naked eye and originate from power plants, fires, and ...

  • On the influence of sea-surface temperature on mesoscale flows: an example from the city of Athens

    The differences resulting in mesoscale flow estimations when using constant or varying (in time and space) sea-surface temperature information have been investigated, with the aid of appropriate air-flow simulations. Results suggest interesting interactions of land and sea surfaces with the atmosphere, which are expected to influence atmospheric flow modelling and air quality management in ...

  • The value of accurate air quality forecasts

    The value of accurate air quality forecasts critically depends upon how the information will be used. This paper proposes a simple model of private firm decision-making under uncertainty to consider potential economic applications and benefits from accurate air quality forecasts. It uses the findings of a survey of employees from five large employers in southern New Hampshire and northeastern ...

  • Synergetic use of TERRA/MODIS imagery and meteorological data for studying aerosol dust events in Cyprus

    This paper presents the results from the analysis of TERRA/Moderate Resolution Imaging Spectrometer (MODIS) images for the detection and mapping of particulate air pollution in Cyprus. For this purpose, a set of selected air pollution events for the year 2002 was used, mainly associated with dust transported over the area from the surrounding deserts. The results depict the potential of the use ...

  • Review of the requirements for models and model applications

    Requirements for models and model applications are reviewed on basis of the Dobris Assessment report and the practice in EU legislation and international organisations, and from the responses of a questionnaire sent to 38 European countries. Model applications are frequently used for regulatory and general assessment purposes by various users (scientists, air quality managers, policy-makers). ...

  • Development of air quality indices for Mumbai, India

    This paper proposes a simple approach for developing air quality indices for different sites in an urban region of India. The database used for calculating these indices included various physical and chemical characteristics of suspended particulate matter, such as particle size distribution, chemical (elemental) properties and parameters governing the acidity of precipitation. The indices were ...

  • A decision support system for air quality management combining GIS and optimisation techniques

    This paper describes a multi-tiered approach to the design of plans and policies for urban environmental management, in particular air quality, as related to the energy and transportation sectors. The approach is based on the iterative combination of sectoral and global optimisation models, including a discrete multi-criteria approach, and spatially distributed air quality models. The approach ...

  • A GIS based air quality system for the Apulia region, southern Italy

    A GIS based air quality modelling system has been developed in Apulia region in the Southern Italy, to support local authorities in air quality management. Meteorological and dispersion simulations were performed for the year 2005. Predictions have been compared with concentration data from the air quality monitoring network. Results evidence a good correlation between predictions and ...

  • Chromatotec monitor air quality in Arcachon Bay through its own air quality station

    Chromatotec® made this summer the inauguration of its private monitoring station in Andernos-les-Bains. With a wealth of experience, thanks to which it already deployed massively its systems around the world, the group wanted to implement its own monitoring station to have complementary information to the actual air quality network. These data will allow the group to extend its ...

  • Air quality indexing

    In an attempt to meet the public's needs for information on air quality a variety of indexes have been developed and they continue to evolve. To show the complexity and the diversity of such indices, a variety of current air quality indices are described here and compared in regard to their performance and ability to deliver quality information. A number of characteristics seem desirable for an ...

  • Uncertainty analysis of modelling studies included in air quality assessments

    This paper deals with the development of a quality analysis/quality control (QA/QC) methodology for modelling studies associated with air quality assessments. Among other benefits, this will allow data quality objectives for model input data to be derived and the importance of policy oriented model applications to be assessed. The procedure for evaluating model uncertainty has profited from a ...

  • Monitoring with the use of passive samplers ? a useful source of information for the mapping and modelling of urban atmosphere pollution

    Due to human activities, increasing numbers of harmful substances are emitted into the atmosphere; they are recognised as potentially dangerous to living organisms, mainly because of their toxicity. Among others, compounds from the BTEX group, e.g. benzene, toluene, ethylbenzene and xylenes, are considered as such toxic substances. They are present in the air above urbanised as well as rural ...
