  • Dispersion modelling near tunnel exits: simulation and measurements

    Measurements of car exhaust gases were made in May/June 1995 in the vicinity of the Bielefeld tunnel. CO and NOx from car exhausts were measured to allow comparison with a model simulation. Ozone was also measured. These measurements were made using commercial continuous analysers. A valve control system was used to investigate the dispersion of the trace gases. This allowed measurements at ...

  • A linear programming approach to evaluate economic instruments for intra-firm SPM emissions reduction trading within M/s Tata Steel, Jamshedpur

    A linear programming model is developed to calculate optimum SPM abatements at different emitting sources of M/s Tata Steel to achieve the abatement limits for the environmental bubble with least cost. An environmental bubble with its limit equal to the sum of permitted SPM emissions at all the emitting sources of M/s Tata Steel is considered. The optimum SPM abatements at different emitting ...

  • Real-World Vehicle Emissions: A Summary of the 15th Coordinating Research Council On-Road Vehicle Emissions Workshop

    ABSTRACT The Coordinating Research Council held its 15th workshop in April 2005, with nearly 90 presentations describing the most recent mobile source-related emissions research. In this paper, the authors summarize the presentations from researchers who are engaged in improving our understanding of the contribution of mobile sources to air quality. Participants in the workshop discussed ...

  • Real-world vehicle emissions

    The Coordinating Research Council (CRC) convened its 18th On-Road Vehicle Emissions Workshop March 31–April 2, 2008, with 104 presentations describing the most recent mobile source-related emissions research. In this paper we summarize the presentations from researchers whose efforts are improving our understanding of the contribution of mobile sources to air quality. Participants in the workshop ...

  • A project "Transformation of air-pollution, modelling its transport and dispersion"

    Information about a new project is given in this contribution. The project is financed by the Czech Ministry of Environment and deals with the problem of summer photochemical smog formation. Field campaigns and utilisation of existing monitoring network data are supposed for analysing both biogenic emissions and emissions due to human activity. An important part of this project consists in ...

  • Traffic pollution modelling in a complex urban street

    This study explores for the first time, the applicability of the Danish Operational Street Pollution Model (OSPM) in the city of Buenos Aires where street canyons are very irregular. The model is applied in an irregular and asymmetric street canyon of a five–lane avenue near a street intersection. Urban background concentrations estimated by the DAUMOD model are considered. Meteorological ...

  • 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). ...

  • Application of The Air Pollution Model (TAPM) to the urban airshed of Bangkok, Thailand

    Bangkok has been faced with air pollution problems as a result of increasing traffic emissions. The Air Pollution Model (TAPM) was employed to simulate carbon monoxide (CO) concentrations based on an emissions inventory data. The hourly CO concentrations from a year-long simulation have been evaluated against observations from six monitoring sites. The simulated concentrations were evaluated ...

  • Studying the influence of biogenic emissions on AOT40 levels in Europe

    It is well known that the uncertainties in determination of biogenic emissions are very large (some authors claim that these emissions are underestimated in certain areas of the world by up to ten times). On the other hand, anthropogenic emissions in some areas of the world have been reduced very considerably during the last two decades (this is especially true for Europe). This fact shows ...

  • The Air Quality Management Decision Support System (AQMDSS) for Beijing, People's Republic of China

    The People's Republic of China (PRC) has been experiencing rapid economic and industrial growth with associated increased air pollution. Government officials strive to improve air quality while maintaining growth. Implemented control measures have not achieved air quality goals; therefore, the Beijing Municipal Environmental Protection Bureau turned to air quality models to help identify sources ...

  • A fine-resolution modelling study of pollution levels in Bulgaria. Part 2: high ozone levels

    Ozone pollution may cause damage to plants, animals and human beings when certain critical levels are exceeded. Therefore, it is important to study actual ozone levels and their relationship with the related emissions. Several secondary indices, directly related to the damages, are studied in this paper, rather than the proper ozone concentrations. Two versions (rough and fine grid ones) of the ...

  • A fine-resolution modelling study of pollution levels in Bulgaria. Part 1: SOx and NOx pollution

    Two versions of the Danish Eulerian Model (DEM) with resolutions of 50 and 10 km on the Europe domain have been used to study: (i) where the highest SOx and NOx Bulgarian pollution levels are located; (ii) how great is the influence of European emission sources on the pollution levels in Bulgaria; and (iii) whether it is possible to evaluate the changes of the ...
