AirWatch | General Air Quality Health Risk

How to read this map

Primary: current modeled U.S. AQI from Open-Meteo/CAMS at representative state points.
Exposure: CDC/ATSDR 2022 state population, available as its own map layer.
Vulnerability: population-weighted CDC/ATSDR SVI.
NWS: active air-quality/smoke/dust/ash products. If none are active, the previous 7 days are shown as muted context.

Where is current modeled air quality most concerning after accounting for population, vulnerability, and NWS air-health products?

Derived attention score

AQI hazard = min(60, 0.40 × U.S. AQI)
Exposure = clamp(0,15,5 × (log10(population) − 4))
Vulnerability = 15 × population-weighted SVI
Active NWS bonus = min(10,eventWeight / 4.5)
Total = capped at 100

Previous-7-day NWS products are context only and do not add to the current score.
