  • Evaluation of the influence of micrometeorological data on concentration estimates

    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 advection-diffusion equation and includes profiles of wind and eddy diffusivity for the entire ...

  • Sensitivity analysis of the modelled deposition of 137 Cs on the Japanese land following the Fukushima accident

    Dispersion of radioactive material released to the atmosphere from the Fukushima Daiichi Nuclear Power Plant accident in Japan was modelled to assist the French Government in effectively providing public health advice to its citizens in Japan. It required estimation of radiation doses based on realistic scenarios and atmospheric dispersion modelling. In this paper, sensitivity studies are ...

  • Atmospheric dispersion and individual exposure of hazardous materials. Validation and intercomparison studies

    In a previous study, new approaches have been introduced in the CFD-RANS modelling, according to which the concentration time scales are estimated as a function not only of the flow turbulence time scales but also of the pollutant travel times. The new approaches have been implemented for the calculation of the concentration fluctuation dissipation time scale and the maximum individual exposure ...
