Air quality today
The air quality in Datteln today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 7.104 and a PM10 reference value of 9.946, based on four valid observations.
Data are shown via OpenAQ. 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 Datteln air‑quality record draws from a single monitoring station, Datteln‑Hagem, which supplies data for five pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm and smaller (PM₁₀), fine particulate matter 2.5 µm and smaller (PM₂.₅), and sulfur dioxide (SO₂). Because there is only one row of measurements, the dataset does not capture spatial variation across the city.
The most recent observations are from 2026‑02‑10 17:00 UTC for NO₂, PM₁₀, PM₂.₅ and SO₂, while the NO value dates back to 2024‑03‑11 11:00 UTC, making it considerably older than the other parameters. All five pollutants are reported as single values with no spread: the minimum, median and maximum are identical for each – NO 10.022 µg/m³, NO₂ 19.677 µg/m³, PM₁₀ 9.946 µg/m³, PM₂.₅ 7.104 µg/m³ and SO₂ 6.37 µg/m³ – indicating that only one measurement per pollutant is currently available.
Because the dataset consists of a single recent row for four pollutants and an older entry for NO, it provides a very limited snapshot of Datteln’s air quality at specific moments rather than a continuous picture. The lack of multiple stations or repeated measurements means that conditions can differ in other parts of the city or at other times, and users should keep in mind that this narrow coverage may not reflect broader temporal or spatial patterns.
