What the data includes

The Decatur County air‑quality feed includes five measured parameters from a single monitoring location: PM1, PM2.5, relative humidity, temperature and the particle count UM003. All of the latest readings were recorded on 2026‑02‑11 at 01:00 UTC, which falls within the “updated within 7 days” freshness window, so the data are currently fresh for every pollutant.

Because there is only one reporting station, each pollutant has a single value that also serves as its minimum, median and maximum. PM1 registers at 0.0 µg/m³, while PM2.5 shows a concentration of 0.03616666719317436 µg/m³. Relative humidity is measured at 49.75749969482422 %, temperature at 21.55466686884562 °C and the UM003 particle count stands at 147.26916681925454 particles/cm³. The lack of variation means there is no observable spread or percentile range for any of these metrics in the current dataset.

With only one row per pollutant, coverage across Decatur County is limited to a single point in space and time. Consequently, while the timestamps are recent, the data cannot capture spatial differences or short‑term fluctuations that may occur elsewhere in the county. Users should keep in mind that conditions can vary by location and moment, and that additional monitoring sites would be needed to provide a fuller picture of air quality across Decatur County.
