Nearest valid 0.4° model grid cell; gases use matching model-level 137 temperature, humidity, lnsp and hybrid coefficients. This global model does not resolve street-level exposure.
CAMS model-based US AQI estimate
85 COMPLETE
Window ending 2026-10-01T15:00:00+00:00; window model run 2026-09-30T12:00:00+00:00. Contributors: co, no2, o3, pm10, pm2_5, so2.
Experimental trailing model estimate using EPA May 2026 breakpoints. Not a station observation, official daily maximum, or NowCast. Partial estimates do not imply six-pollutant completeness.
