The index is set by PM2.5 at 0.8 µg/m³ (sub-index 4).

These values come from the Copernicus atmospheric model as distributed by OpenWeather, sampled at the coordinates of Milwaukee. They are modelled concentrations on a grid, not readings from a monitoring station inside the town, so neighbouring localities in the same grid cell will show similar figures. Treat them as a regional indication rather than a measurement taken at your street.
