The AERMOD modeling system is recognized by Appendix W to 40 CFR Part 51 (“Guideline on Air Quality Models”) as the preferred air dispersion model for assessing impacts in the near-field (< 50km from a release). Part 1 of this webinar series introduces the AERMOD modeling system components, the theory behind AERMOD's calculations, and presents model input requirements such as meteorological data processing, building downwash, and more. Learn techniques to efficiently run the AERMOD model.
