How smoke reaches Cincinnati
Cincinnati's river-valley geography matters more than its distance from the fires: smoke that does reach the Ohio Valley can get trapped under summer inversions and linger. Aged Canadian smoke here often blends with local haze, nudging AQI up for days rather than spiking it. That is why SmokeDar reports two numbers for Cincinnati: smoke aloft (modeled aerosol optical depth from Copernicus CAMS) and surface air (PM2.5 and US AQI, observed AirNow monitor data when a monitor is nearby). They are different things, and they often disagree.

AQI 0–50 is good and 51–100 is moderate; ordinary days. From 101–150, sensitive groups (kids, older adults, pregnant people, anyone with heart or lung conditions) should shorten hard outdoor exercise. Above 150, everyone should cut both time and intensity outdoors. The full playbook is in the Smoke Guide.
