DATE: Wednesday, August 13, 2014


TIME: 3:00 PM – 5:00 PM



After attending the webinar, participants will be able to:

  1. Correctly use model names and acronyms in discussion or written materials
  2. Identify the types of modeling needed to address a variety of air quality issues
  3. Identify photochemical grid models for SIP planning
  4. Identify dispersion models for point source analysis
  5. Define source apportionment modeling and receptor modeling and their role in identifying source contribution to air pollution
  6. Identify the step to develop an emissions inventory
  7. Recognize & understand the purpose of meteorological models



Part 1 – Types of Models

—  Receptor models

—  Photochemical models

—  Dispersion models

—  Trajectory models

—  Emissions models

Part 2 – Setting up Regional Photochemical Air Quality Models – CMAQ & CAMX

—  Modeling Domain

—  Boundary Conditions

—  Grid Structure

—  Meteorological Model

—  Pre-processing/post-processing

Part 3 – Emissions Modeling

—  Background


Part 4 – More about Using Models for SIPs

—  What is sensitivity modeling?

—  In regional modeling, how can we tell what sources are causing the model to predict violations?

—  If the model is run for only one year, how can you compare that to a three-year design value?

—  What is a Weight of Evidence demonstration?
