Modelling the dispersion of pollutants in the atmospheric boundary
layer. The experience of ARIANET, products and applications.

Abstract

The atmospheric dispersion of pollutants is one of the main phenomena
that must be described to obtain an assessment of the air pollution.
Among the tools that may allow this, numerical dispersion models
constitute one of the main ones. They allow to reconstruct the behavior
of pollutants released into the atmosphere by both human activities
(transport, heating, industry) and natural phenomena (volcanoes, fires,
sand storms). Pollutants are transported by wind and dispersed by
turbulence, chemically transformed, deposited by surface contact or
removed by rainfall: the aim of the models is to reproduce this complex
phenomenology to assess air quality levels that may be harmful to human
health and ecosystems. ARIANET has a more than ventennial history in
both developing and using this kind of models for many applications at
different scales, ranging from impact studies of local industrial
pollutant sources to the development, use and maintenance of air quality
forecast systems at the national scale. Aim of the seminar is to
describe the various products developed and available at ARIANET,
including both the Lagrangian Particle Dispersion Model SPRAY and the
Eulerian Chemical Transport Model FARM widely used by many institutions
in Italy and to give an overview of the many applications of these
modeling tools such as in the fields of impact assessment, emergency
response, odours, fires, and forecasting systems.
