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 Hagen contains a single monitoring location – the Graf‑von‑Galen‑Ring station – which supplies measurements for four pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter up to 10 µm (PM₁₀) and fine particulate matter up to 2.5 µm (PM₂.₅). Because there is only one row of data, the coverage across the city is limited to this point.
The most recent values are fairly fresh for three of the pollutants, with NO₂, PM₁₀ and PM₂.₅ all last updated on 2026‑02‑10 at 17:00 UTC, meaning they were recorded within the past three days. The NO measurement is older, dated 2024‑03‑11 at 11:00 UTC, so it reflects conditions from almost two years ago and is flagged as “old data”. All four pollutants have a single reported value, which also serves as their minimum, median and maximum – NO at 59.323 µg/m³, NO₂ at 30.418 µg/m³, PM₁₀ at 16.04 µg/m³ and PM₂.₅ at 10.204 µg/m³.
Because the dataset consists of only one station, there is no spread or variability to describe; each pollutant’s range collapses to a single point. The freshness disparity shows that while most recent data are up‑to‑date, the NO reading is considerably outdated, highlighting an uneven temporal coverage across pollutants. Consequently, any snapshot of air quality in Hagen based on this source represents conditions at a specific location and time rather than a comprehensive citywide picture.
