What the data includes

The dataset for Wuppertal contains measurements from two monitoring sites, providing a total of nine recent observations across the five pollutants tracked in this city. All five substances – 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) – are represented, but the amount of data varies between them.

The newest NO reading dates back to 2024‑03‑11 11:00 UTC, while the other four pollutants have updates from 2026‑02‑10, with O3 recorded at 08:00 UTC and the rest at 17:00 UTC on that day. This means that for most compounds the latest information is less than three days old, but NO data is considerably older, limiting its relevance to current conditions.

Across the two stations the observed values show a modest spread. For NO the measurements range from 6.388 µg/m³ up to 82.295 µg/m³, with a median of about 44.34 µg/m³; for NO2 the range is tighter, between 14.3 and 32.719 µg/m³, centred around a median of 23.51 µg/m³. Particulate matter levels are low overall: PM10 varies from 7.653 to 14.682 µg/m³ (median 11.17) and PM2.5 from 6.048 to 8.559 µg/m³ (median 7.30). Ozone is represented by a single value of 42.744 µg/m³, so no range can be derived for that pollutant.

Because the dataset includes only two monitoring locations, conditions in other parts of Wuppertal may differ from what these numbers show, especially for NO where the most recent measurement is over two years old.

Data notes

The data shown for Wuppertal are based on seven valid measurements and were refreshed recently, with the latest update recorded at 2026‑02‑10T17:00:00+00:00 (updated within 3 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.
