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 Warstein contains measurements from a single monitoring station and includes four pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO2), particulate matter up to 10 µm (PM10) and particulate matter up to 2.5 µm (PM2.5). In total there are four rows of data, one for each pollutant. The timestamps show that the NO reading is older, last updated on 2024-03-11 11:00 UTC, while the other three pollutants have been refreshed very recently, with their latest values recorded on 2026-02-10 17:00 UTC. This means that most of the available data reflects conditions from just a few days ago, but the NO measurement is more than two years out‑of‑date.
Across the four pollutants the reported values are all single observations rather than ranges. The NO concentration is 1.769 µg/m³, NO2 stands at 10.124 µg/m³, PM10 measures 8.921 µg/m³ and PM2.5 records 7.501 µg/m³. Because each pollutant has only one recorded value, the median, minimum and maximum are identical for every metric, indicating no observed variability within this dataset. The spread between the highest (NO2 at 10.124 µg/m³) and lowest (NO at 1.769 µg/m³) values is modest, but the lack of multiple readings limits any assessment of fluctuations over time.
Overall the coverage is limited to a single site, and while three pollutants have up‑to‑date measurements, the NO data is considerably older. Consequently, the snapshot provides only a narrow view of air quality in Warstein at specific moments, and conditions can differ across other locations or times not captured here.
