AIR - Atmosphere, Impact & Risk group offers training to pollution and atmospheric dispersion to:

  • government and regulation authorities, air quality monitoring network, local authorities, etc..
  • industrials
  • environmental consultants in charge of impact and safety assessment studies

These courses are organized in the framework of ECL Pro, the professionnal formation service of the Ecole Centrale de Lyon.

Atmospheric Pollution (1 day)

  • Regulations in force:
    • Regulated pollutants
    • Impact studies and risk
  • Basics of Meteorology:
    • Atmospheric flow and turbulence
    • Stability phenomenon
    • Influence of complex terrain (terrain, obstacle)
  • Atmospheric dispersion:
    • Description of atmospheric plume
    • Influence of stability
    • Dispersion in complex terrain
    • Physicochemical processes
  • Tools and approach to study air pollution
    • Field measurements
    • Modeling: the different scales (local, regional, continental models)
      • Different modeling approaches: Eulerian Lagrangian, Gaussian models
