Latest sensor values
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 two pollutant measurements are available: PM10 and PM2.5, each reported from a single monitoring location in Apache Junction. Both pollutants have a most‑recent timestamp of 2026-02-11 00:00 UTC, which falls within the “updated within 7 days” freshness category, indicating that the latest readings are relatively current.
For PM10 the dataset shows a uniform value of 25.0 µg/m³ across its minimum, median and maximum, with the 10th and 90th percentiles matching this figure as well. PM2.5 is similarly consistent at 5.1 µg/m³ for all statistical points. Because only one station contributes data, there is no spatial spread of measurements within the city, and the lack of variation means the reported numbers represent a single point in time rather than a range of conditions across Apache Junction. Consequently, while the timestamps are fresh, the limited coverage should be considered when interpreting these figures for broader city‑wide air quality insights.
