How smoke reaches Cleveland
By the time wildfire smoke reaches Cleveland it has usually traveled well over a thousand kilometers, aging and mixing along the way. Lake Erie's shoreline circulation can hold that aged haze against the city, adding to the industrial corridor's baseline particle load. That is why SmokeDar reports two numbers for Cleveland: 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.
