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 air‑quality data for Hürth includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM₁₀) and particulate matter 2.5 µm or smaller (PM₂.₅). All of these are represented in a single monitoring station, giving a total of five data rows for the city.
The newest measurements were recorded on 2026‑02‑10 at 17:00 UTC for NO₂, O₃, PM₁₀ and PM₂.₅, while the NO value dates back to 2024‑03‑11 at 10:00 UTC, making it the only older entry in the set. Each pollutant shows a single reported figure because the minimum, median and maximum values are identical: NO is 1.21 µg/m³, NO₂ is 8.342 µg/m³, O₃ is 45.391 µg/m³, PM₁₀ is 2.376 µg/m³ and PM₂.₅ is 1.133 µg/m³. Because there is only one observation per pollutant, the spread (10th‑90th percentile) is zero for all of them.
Overall the dataset is very limited in scope: with just one station providing a single recent snapshot for most pollutants, it cannot capture spatial or temporal variation across Hürth. The presence of an older NO reading highlights that not every pollutant has been updated within the last few days, so conditions may differ at other locations or times. Users should keep in mind that this snapshot reflects only the moment captured by the lone sensor and does not represent a comprehensive view of air quality throughout the city.
