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 …

A Lagrangian stochastic model (MicroSpray), able to simulate the airborne dispersion in
complex terrain and in presence of obstacles, was modified to simulate the dispersion of …

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 …

The transport and diffusion processes of a tracer gas released near the ground in the Rhine
valley region, in Central Europe, during the 1992 TRACT field experiment, are simulated by …

A semi-analytical Lagrangian particle model to simulate the pollutant dispersion during low
wind speed conditions is presented and tested. The method relies to a stochastic integral …

The behavior of probability density functions (pdfs) of the velocity and temperature
fluctuations in the unstable surface layer is systematically studied within the framework of …

Three different modelling techniques to simulate the pollutant dispersion in the atmosphere
at the microscale and in presence of obstacles are evaluated and compared. The Eulerian …

The atmospheric impact of stack emissions from a power plant (tri-generator and boilers)
that will be installed in an urban area in the central Po valley (Northern Italy), characterized …

Analysis of published data on the third-and fourth-order moments of vertical velocity in the
atmospheric boundary layer is performed, and it is shown that turbulence is non-Gaussian …

Abstract It is known (Thomson, 1987) that Ito's type stochastic models (LS) satisfy the well-
mixed condition and hence are physically consistent. An Eulerian probability density …
