Air quality today

The air quality in Münster today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 8.404 and a PM10 reference value of 10.775, based on seven valid observations collected via OpenAQ.

These figures indicate that the current concentrations are within the range associated with the Good category. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Münster includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀) and particulate matter ≤ 2.5 µm (PM₂.₅). The information comes from nine individual rows that belong to two monitoring stations, so the spatial coverage is limited to a small number of locations within the city.

The most recent measurements are fairly fresh for four of the pollutants: NO₂, PM₁₀, PM₂.₅ and O₃ were all recorded on 2026‑02‑10 at 17:00 UTC, while the latest NO value dates back to 2024‑03‑11 at 11:00 UTC, making it considerably older than the others. Across the dataset the median values are 9.27 µg/m³ for NO, 29.23 µg/m³ for NO₂, 21.85 µg/m³ for O₃, 9.46 µg/m³ for PM₁₀ and 7.65 µg/m³ for PM₂.5. The observed ranges show that NO varies from about 3.6 to 14.9 µg/m³, NO₂ spans roughly 25.8 to 32.7 µg/m³, PM₁₀ runs between 8.1 and 10.8 µg/m³, PM₂.5 is recorded from 6.9 to 8.4 µg/m³, and O₃ has a single reported value of 21.85 µg/m³.

Because the data come from only two sites, conditions elsewhere in Münster may differ from those captured here, especially for NO where the most recent reading is nearly two years old. The overall picture shows relatively tight spreads around the median for the particulate matter and nitrogen dioxide measurements, while the older NO data point highlights a gap in up‑to‑date coverage for that pollutant.

Data notes

The data shown for Münster 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 collection; air quality can vary across different neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
