🔥 Wildfire Smoke Resilience: AQI & Clean-Air Shelter Lab

A 3D Gaussian-plume model of wildfire smoke drifting toward a city: tune fire distance, wind and intensity to see PM2.5 and AQI shift, and switch on a HEPA clean-air shelter to see indoor exposure drop.

A Gaussian-plume model of wildfire smoke drifting toward a city: tune the fire's distance, intensity and wind to watch PM2.5 and AQI shift on live-tinted buildings, then toggle a HEPA-filtered clean-air shelter and see indoor exposure drop far below outdoor levels.

🔬 What It Demonstrates

Smoke concentration downwind depends on emission rate, wind speed and distance-driven dispersion — the same Gaussian plume physics used in real air-quality forecasting. PM2.5 is converted to the official EPA AQI scale in real time.

🎮 How to Use

Drag the fire distance, intensity and wind sliders to change the plume, rotate wind direction to send smoke toward or away from the city, and switch the clean-air shelter's HEPA filtration on and off to compare indoor vs. outdoor AQI.

💡 Did You Know?

Well-sealed rooms with HEPA filtration can cut indoor PM2.5 by 80–90%, which is why public-health guidance during smoke events centres on "clean air shelters" rather than evacuation alone.
