How smoke reaches Grand Rapids
Plumes bound for Grand Rapids typically cross Wisconsin and Lake Michigan first. The lake crossing cools and stabilizes the air, so smoke often stays aloft on arrival, then mixes down inland as the afternoon heats up over western Michigan. That is why SmokeDar reports two numbers for Grand Rapids: 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.
