Studies using AERMOD and CALPUFF models reveal that pollutants disperse unpredictably, affecting workers and nearby communities. ...
CUSTOMER: APB, Port Authority of the Balearic Islands USER: APB, Port Authority of the Balearic Islands LOCATION: Balearic Ports ENVIRONMENT: Ports YEAR: 2019 The APB, in its goal to intensify the concern for the environment, has designed an environmental management system certified by AENOR according to ISO 14001: ...
In the context of the FEDER AIRCITY project, Paris City is modelled with a 3 m resolution with the purpose of computing pollutant concentration relevant for human exposition. This project involves AIRPARIF (Ile-de-France Air Quality Monitoring Network), for emission and immission data, CEA (French Atomic and Alternative Energy Agency) for HPC availability, ...
The application of CALMET/CALPUFF modelling system is well known, and several validation tests were performed until now; however, most of them were based on experiments with a large compilation of surface and aloft meteorological measurements, not always available. Also, the use of an operational large smokestack as tracer source is not so usual. In this work, CALPUFF ...
Back-trajectory techniques are extensively used to identify the most probable source locations, starting from the known pollutants concentration data at some receptor sites. In this paper, we review the trajectory statistical methods (TSMs) that are most used in literature for source identification, which are essentially based on the concept of residence time (RT), and we ...
A dispersion model for continuous releases of pollutants in the atmospheric boundary layer is applied to study the influence on modelled concentrations of different estimates of the key micrometeorological variables that represent the dispersion processes. The modelling approach is based on the ...
We present a modelling system for the estimation of forest fire emissions ( prebolchem-fire ) and their inclusion in the atmospheric composition model BOLCHEM. ...
Local PM10 emissions include traffic emissions, local seasonal heating sources from residential housing, industrial and point sources, and fugitive sources. Mathematical modelling has been performed using CALPUFF model, driven by meteorological fields created by CALMET meteorological model. ...
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 ...
This paper reviews recent findings in the field of flow and pollutant dispersion modelling around buildings and within complex urban geometries. ...
A Hybrid Cells in Series (HCIS) model with decay (HCIS–D) has been conceptualised to simulate advection, dispersion, decay governed pollutant transport. ...
Experiments 4. 10 and 12 have been modelled using the air pollution dispersion model ADMS. and the results compared with the measured concentrations of SFe. ...
Abstract Increased global environmental awareness has fostered widespread use of remote automated weather station (RAWS) networks to monitor meteorological conditions, and reliance on atmospheric dispersion modeling for decisions concerning pollutant dispersion. Dispersion models require as ...
Forum for Air Quality Modelling in Europe (FAIRMODE) sub–group 2 (SG2) on the 'Contribution of natural sources and source apportionment' has been formed in response to the need for a harmonised European approach in the use of models for source apportionment, addressing the requirements of the current Air Quality Directive 2008/50/EU. ...
The definition of appropriate performance criteria is one of the key issues for the benchmarking of air quality models in regulatory applications. As part of the FAIRMODE benchmarking activities (Thunis et al., 2010), suitable criteria for air quality modelling in the frame of the EU air quality directive (AQD) 2008 are proposed and tested. ...
Dispersion of chemically reactive pollutants in the urban canopy layer (UCL) over twelve idealised two–dimensional (2D) street canyons of unity aspect ratio in isothermal conditions is examined. The reversible NOx–O3 mechanism is integrated into a large–eddy simulation (LES) model. The ground–level NO emission in the first street canyon and the ...
The paper presents part of the research on model development of pollen dispersion and pollen deposition in an urban canopy layer. ...
Models of atmospheric pollutant transport need information about the structure of the atmospheric boundary layer (ABL). ...
A mathematical method for real–time calculations of cloudshine doses/dose rates used for purposes of online assimilation of model predictions with observations incoming from terrain is proposed. Model predictions of cloudshine doses have to be calculated simultaneously in an array of positions located on terrain around a nuclear facility. ...
In this paper, two wavelet–based methods are proposed to obtain lateral dispersion coefficients from such time series. These methods, associated with a specific wind model, have been tested by using wind velocities recorded, with an ultrasonic anemometer, on a typical suburban site located in the southern part of the Paris region (France). Both of them give ...
