Accounting for the current knowledge of the planetary boundary layer (PBL) structure and
characteristics, a new set of turbulence parameterisations to be used in atmospheric …

Lagrangian particle models are powerful tools to simulate the atmospheric dispersion of
gaseous releases. Although having a quite complex mathematical basis (Thomson, 1987 …

In this paper, the MicroSpray 3-D Lagrangian particle dispersion model is presented and
reviewed, and several validation studies are shown. Starting from its core, based on a 3-D …

The classical statistical diffusion theory and the observed spectral properties are used to
estimate the Kolmogorov constant C0 under different stability conditions and for the three …

Six one–dimensional models, based on the Ito–type stochastic equation, are presented and
compared. Four of these take into account up to the fourth order moment of vertical velocity …

Eulerian turbulence observations, madein the surface layer under unstable conditions (z/L>
0), by a sonic anemometer were used to estimatethe Lagrangian structure function constant …

The inertial subrange Kolmogorov constant C 0, which determines the effective turbulent
diffusion in velocity space, plays an important role in the Lagrangian modelling of pollutants …

A new method for deriving the Lagrangian decorrelation time scales for inhomogeneous
turbulence is described. The expression for the time scales here derived for the convective …

Dispersion in low wind speed conditions is governed by meandering that disperses plumes
over wide angular sectors, thus glc are lower than predicted by Gaussian models. It was …

Considering a Lagrangian stochastic particle dispersion model and diffusion experiments,
two turbulence parameterizations have been tested. The parameters obtained from the …
