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 dataset for Olpe contains a single monitoring location that reports five atmospheric variables. PM1 is recorded at 11.92 µg/m³, PM2.5 at 27.53 µg/m³, relative humidity at 62.39 %, temperature at 10.46 °C, and particle count (UM003) at 732.59 particles/cm³. All five measurements share the same most‑recent update timestamp of 2026-02-10 19:00 UTC, indicating that the latest data are less than three days old.
Because only one station contributes rows, the coverage across pollutants is uniform – every listed parameter has a single value rather than a range of observations. The statistical summary shows identical minimum, median and maximum values for each pollutant, reflecting the lack of multiple readings over time at this site. Consequently, there is no spread to describe variability; the dataset provides a snapshot rather than a trend.
The freshness of the data is consistent across all variables, with the last update occurring on 2026-02-10. While the timestamp meets the “updated within three days” criterion, the absence of additional rows means that temporal changes in air quality cannot be captured from this source alone. Users should keep in mind that conditions may differ elsewhere in Olpe or at other times, and the single‑point measurement offers only a limited view of the city’s atmospheric state.
