Dispersion modeling

Run AERMOD and compare results to the standards.

Set up an AERMOD run in plain language. Use the output to check the compliance demonstration.

What you can do

• Stage meteorology and build AERMET and AERMOD input decks
• Pull background concentrations from nearby EPA AQS monitors
• Build terrain with AERMAP and building downwash with BPIPPRM
• Work NO₂ conversion tiers with ozone data
• Score design values against the NAAQS and PSD increments
• Draft a modeling protocol per 40 CFR Part 51 Appendix W

The model panel

A run opens its own panel beside the chat. Place stacks, line sources, open pits, and buildings on an interactive site layout; read the meteorology as a wind rose; and see results as isopleth contours over the map, with run status live while AERMOD works. Runs stay attached to the chat, so you can come back to one later.
