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 location in Cañon City contributes to the OpenAQ feed, providing a total of two rows—one each for PM10 and PM2.5. Both measurements were last updated on 2026-02-11 00:00 UTC, which falls within the “updated within 7 days” freshness category.
For PM10, the single reading shows a value of 18.0 µg/m³, with the minimum, median and maximum all equal to 18.0 µg/m³, indicating no observed variation in this dataset. The PM2.5 measurement is similarly uniform at 2.8 µg/m³ across its min‑med‑max range. Because only one station supplies data, the coverage is limited to a single point in the city, and the lack of multiple rows or older timestamps means there is no broader temporal or spatial picture available. Consequently, while the reported figures are recent, they represent a snapshot rather than a comprehensive view of air quality conditions across Cañon City.
