Air quality today

The air quality in Oberhausen today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).

Measurements recorded for the day show a PM2.5 reference value of 6.779 and a PM10 reference value of 9.734, based on six valid observations from OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The data set for Oberhausen contains four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO2), particulate matter 10 µm or less (PM10) and particulate matter 2.5 µm or less (PM2.5). All values are reported in micrograms per cubic metre. The city’s air‑quality record is built from two monitoring stations, each providing a single row of data for every pollutant, so the total number of rows equals eight.

Freshness varies across the pollutants. The most recent NO measurement dates back to 2024‑03‑11 11:00 UTC and is flagged as “Old data”, while the remaining three pollutants have been updated within the last three days (most recent timestamp 2026‑02‑10 18:00 UTC). This means that, for the current view, NO is considerably older than the other compounds.

The observed ranges are narrow. For NO the values span from a minimum of 57.696 to a maximum of 70.496 µg/m³, with a median of 64.096 µg/m³; the 10th and 90th percentiles sit at 58.976 and 69.216 respectively, indicating limited variability across the two stations. NO2 shows an even tighter spread, ranging only from 30.082 to 30.724 µg/m³ (median 30.403), while PM10 varies between 9.734 and 10.530 µg/m³ (median 10.132) and PM2.5 between 6.433 and 6.779 µg/m³ (median 6.606). The percentiles for the particulate matter series confirm this consistency, with differences of less than one microgram per cubic metre between the lower‑ and upper‑decile values.

Because the dataset relies on just two stations, spatial coverage is limited; conditions measured at Oberhausen Mülheimer Straße 117 (NO) and Oberhausen Duisburger Straße (NO2, PM10, PM2.5) may not capture variations elsewhere in the city. Moreover, the older NO reading suggests that the current picture for this pollutant could be outdated, while the other three pollutants reflect more recent conditions.

Data notes

The data shown for Oberhausen is based on six valid measurements and was refreshed within the past three days, with the latest update recorded at 2026‑02‑10 18:00 UTC. This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
