Air quality today
The air quality in Lüdenscheid is classified as Good today. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 value of 5.998 and a PM10 value of 6.295, based on four valid observations recorded via OpenAQ.
These figures reflect the current assessment for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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 Lüdenscheid air‑quality record consists of a single monitoring location on Lennestraße, so all five pollutants are represented by one row each. The dataset therefore contains five rows in total – one for NO, one for NO₂, one for O₃, one for PM10 and one for PM2.5.
The most recent measurements were taken on 2026‑02‑10 at 18:00 UTC for four of the pollutants (NO₂, O₃, PM10 and PM2.5), while the NO value dates back to 2024‑03‑11 at 11:00 UTC. This means that, apart from nitrogen monoxide, the data are fresh within the last three days; the older NO entry is more than a year old. All five pollutants have a single reported concentration with no variation across the record – each shows identical minimum, median and maximum values (NO 10.009 µg/m³, NO₂ 15.348 µg/m³, O₃ 37.954 µg/m³, PM10 6.295 µg/m³, PM2.5 5.998 µg/m³). Consequently the spread (p10‑p90) is zero for every pollutant, indicating that only one observation per parameter is currently stored.
Because the coverage relies on just one station, the figures describe conditions at a specific point in Lüdenscheid rather than citywide averages. The dataset’s limited temporal depth – especially the outdated NO reading – suggests that short‑term fluctuations elsewhere in the city are not captured here. Users should keep in mind that air quality can differ across neighborhoods and over time, and the present numbers reflect only the most recent snapshot from a single monitoring site.

Data notes
The data shown are based on four valid measurements and were refreshed recently, with the latest update recorded on 2026‑02‑10 at 18:00 UTC (updated within three days). These values represent a snapshot of air quality across Lüdenscheid and may differ by specific neighbourhoods or times of day. Consequently, conditions can vary locally even though the overall city reading is presented here.
