The problem today
Air dispersion modeling
is stuck in 2003.
⏱
3+ days to set up a single AERMOD run
Manual met downloads, AERMET debugging, terrain processing
💻
Windows-only desktop software from the 1990s
License dongles, IT approvals, version conflicts
📊
Results in cryptic text files and static GIF images
Manual post-processing in Excel, hand-drawing isopleths
💸
Pay $300–500/year for free NOAA public data
Vendors repackage government data at a premium
Steps just to run AERMOD today:
1. Download NWS surface data manually
2. Download upper air soundings
3. Run AERMET Stage 1, 2, 3
4. Debug cryptic AERMET errors ⚠
5. Download terrain tiles from USGS
6. Run AERMAP terrain processor
7. Debug AERMAP projection errors ⚠
8. Hand-write .INP file syntax
9. Run AERMOD executable
10. Post-process output in Excel
11. Write modeling protocol (Word)
Total: 2–5 days · $3,000–8,000 in consultant time
