This study was undertaken to assess the influence of traffic on particulate air pollution in an
urban area, and to characterise the short-range transport of the aerosols generated by traffic …

A method was developed in this paper to estimate the spatial and temporal distribution of
vehicle emissions and concentrations in Beijing based on the limited database. The vehicle …

For the atmospheric dispersion of pollutants in low wind conditions, a steady-state
mathematical model has been formulated which takes into account the diffusion in all the …

Investigation of low-wind cases observed during the Urban Turbulent Project campaign
(Torino, Italy) and at the Santa Maria meteorological station (Santa Maria, Brazil) provides …

The structure of the surface boundary layer over homogeneous conditions is nowadays well
understood. However, there is no sufficient knowledge of the corresponding structure over …

An emission inventory based on GIS technology was developed in this study, and used to
estimate the spatial distribution of the stationary and mobile sources in the urban area of …

We examine the performance of two steady-state models, a numerical solution of the
advection-diffusion equation and the Gaussian plume-model-based AERMOD (the …

An analytical solution of three dimensional advection–diffusion equation, including
longitudinal diffusion, for dispersion of air pollutants from a point source at a height close to …

Commonly large shifts of wind direction in low-wind conditions are poorly understood and
are not sufficiently captured by air-quality dispersion model AERMOD. In the low-wind …

The well-known Gaussian plume model has proven to be very useful in simulating the
atmospheric dispersion of air pollutants (both gaseous and particulates). Nevertheless, the …
