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, reporting PM2.5 concentrations measured at the Bondville location. The single reading shows a concentration of 5.9 µg/m³, recorded on 2026-02-10 23:00 UTC, which falls within the “updated within 7 days” freshness category.
Because the dataset contains just this one recent PM2.5 entry, there are no additional pollutants or multiple sites to compare across Champaign County. The observed value is both the minimum and maximum recorded for the city, giving a uniform snapshot rather than a range. With only one station contributing data, spatial coverage is limited, meaning conditions elsewhere in the county may differ from this point-in-time measurement. The timestamp’s recency indicates the information is fairly current, but the lack of broader or older records prevents assessment of variability over time or across locations.
