PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The current station data listed for this city is focused on particulate matter (PM). Only one monitoring row is available for Aurora, Illinois, and it reports a single pollutant: PM2.5 measured in micrograms per cubic metre. The recorded value is 15.7 µg/m³, which is also the minimum, median and maximum observed across that station’s recent readings. This measurement was last updated on 2026-02-11 00:00 UTC, placing it within the “updated within 7 days” freshness category.
Because the dataset contains just a single row, there is no variation in concentration values to describe a range or spread, and coverage is limited to one location rather than a network of sites. The timestamp indicates that the data are relatively fresh, but with only one point it cannot capture spatial differences across Aurora. Consequently, while the figure gives a snapshot of particulate matter at that moment, conditions elsewhere in the city may differ and later updates could change the picture.
