What the data includes

Leverkusen’s OpenAQ feed currently provides data for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). The dataset contains 14 individual rows drawn from three monitoring sites across the city, so each pollutant is represented by a handful of measurements rather than a dense network.

The most recent observations are from 10 February 2026 for NO₂, PM₁₀, PM₂.₅ and O₃, all recorded at 18:00 UTC, indicating that four of the five pollutants have fresh data within the last three days. In contrast, the latest NO reading dates back to 11 March 2024 at 11:00 UTC, making it considerably older than the others. Across the board, the measured values show modest variability: NO ranges from 0.425 to 7.654 µg/m³ with a median of 0.763 µg/m³; NO₂ spans 17.607–34.763 µg/m³ (median 21.38); PM₁₀ varies between 5.373 and 12.897 µg/m³ (median 8.68); PM₂.₅ lies from 3.131 to 9.062 µg/m³ (median 4.99); and O₃ covers 16.404–25.914 µg/m³ (median 21.159). The inter‑quartile ranges are relatively tight, especially for the particulate fractions, suggesting that most recent readings cluster near their median values.

Because only three stations contribute data, spatial coverage is limited; conditions can differ between neighbourhoods not directly monitored. Moreover, the older NO record highlights an uneven temporal freshness across pollutants. Users should keep in mind that these snapshots reflect specific moments at particular sites and may not capture short‑term fluctuations or localized hotspots elsewhere in Leverkusen.

Data notes

The data shown for Leverkusen are based on seven valid measurements and have been refreshed recently, with the latest update recorded at 2026‑02‑10 18:00 UTC; they are considered updated within three days. This snapshot reflects conditions at the time of measurement, but air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
