Practical Air Dispersion Modeling Workshop


This 3-day course is designed for environmental professionals with little dispersion modeling experience who wish to use the AERMOD model or to better understand AERMOD results prepared by others. It is similar to the two-day AERMOD Modeling Computer Lab course, with additional focus on developing a strong understanding of model fundamentals. Course topics include Gaussian model behavior, source characterization, building and terrain data, and results interpretation.

The course includes hands-on modeling exercises and interactive lecture sessions. Course completion will enable attendees to:

  • Develop a strong understanding of the AERMOD model, its input data, and model options
  • Carry out a typical AERMOD modeling analysis
  • Produce and correctly interpret tables, plots, and other output from AERMOD

  • Review of Air Dispersion Modeling Concepts
  • A Layman’s Crash Course on the Physics of the Atmosphere – Its Character, Variability, and Subjective Effect on Pollutant Releases
  • Estimating the Effective Height of Sources
  • Estimating Dispersion from Continuous Releases
  • Estimating Dispersion from Puff, Line, and Area Sources
  • Inputs to Models
  • Screening Models
  • Steps in Performing an Air Quality Analysis
  • The AERMOD Modeling System
  • Project File Management
  • Data Visualization and Analysis
  • “What-if” Scenarios
  • Downwash of Plumes by Structures
  • Consideration of Terrain in Modeling
  • Fundamentals of Meteorological Data Processing
