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 Lünen air‑quality record draws on a single monitoring site – Lünen‑Niederaden – and provides data for four pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter 10 µm or smaller (PM10). In total there are four rows of observations, one for each pollutant, all coming from the same station.
The dataset shows a mixed picture of freshness. The NO measurement is dated 2024‑03‑11 08:00 UTC, which makes it more than two years old, while the readings for NO₂, O₃ and PM10 were all last updated on 2026‑02‑10 17:00 UTC, placing them within the past few days. Because each pollutant has only a single row, the reported minimum, median and maximum values are identical: NO registers at 7.534 µg/m³, NO₂ at 13.742 µg/m³, O₃ at 38.809 µg/m³ and PM10 at 8.111 µg/m³. This lack of variation indicates that the data set captures a single snapshot rather than a range of measurements over time.
With just one monitoring location, the coverage is limited to conditions at Lünen‑Niederaden and may not reflect variations across other parts of the city. The presence of recent updates for three of the four pollutants suggests that most of the current information is fresh, but the older NO value highlights an inconsistency in data recency. Users should keep in mind that the snapshot nature of the figures means they represent a specific moment rather than ongoing trends.

Data notes
The data shown for Lünen reflects three valid measurements and was updated within 3 days, with the latest reading recorded at 2026‑02‑10T17:00:00+00:00. These figures provide a recent snapshot of ambient air quality across the city, but conditions can differ by neighbourhood and change rapidly over short periods. Consequently, the values presented represent an approximate overview rather than a precise, location‑specific reading at any given moment.
