Studio della dispersione di composti in atmosfera tramite modelli lagrangiani a particelle e fotochimici euleriani. Applicazioni a scala regionale e scala urbana

Atmospheric modelling of aerosols and gaseous compounds by Lagrangian particle dispersion models and chemical transport models, mainly applied at a regional scale and urban scale.

Expected change in primary PM10 by vehicular exhaust emissions from 2019 to 2030
Total suspended particles by tyre abrasion at 4 m x 4 m horizontal resolution over Modena

Obiettivi:

  • Stima dell’impatto di sorgenti urbane sulla qualità dell’aria
  • Simulazione di scenari futuri di qualità dell’aria
  • Apporzionamento delle sorgenti di inquinanti atmosferici basato su modellistica di dispersione

Goals:

  • Impact assessment of urban atmospheric emission sources on air quality
  • Air quality scenarios based on emission trajectories
  • Source apportionment of atmospheric pollutants by lagrangian dispersion modelling
