Air quality today

The air quality in Mönchengladbach today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 1.98 and a PM10 reference value of 6.093, based on four valid observations collected via OpenAQ.

Overall conditions meet the criteria for the Good category according to the current assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

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 dataset for Mönchengladbach includes measurements of nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀) and particulate matter ≤ 2.5 µm (PM₂.₅). In total 16 individual rows have been collected from four monitoring stations across the city, giving a modest spatial coverage that captures conditions at several key locations but does not provide a dense grid of observations.

The most recent data are from 2026‑02‑10 18:00 UTC for NO₂, PM₁₀, PM₂.₅ and O₃, while the latest NO reading dates back to 2024‑03‑11 11:00 UTC, making it considerably older than the other pollutants. Across the recent measurements the observed concentrations span a wide range: NO₂ varies from 14.32 µg/m³ up to 56.32 µg/m³ with a median of about 30 µg/m³; PM₂.₅ runs between 1.98 and 14.52 µg/m³, centred around a median of roughly 7.8 µg/m³; PM₁₀ is recorded from 6.09 to 23.79 µg/m³ with a median near 15.6 µg/m³; O₃ shows values from essentially zero (‑0.001) up to 29.10 µg/m³, medianing at about 14.5 µg/m³. The ten‑percentile and ninety‑percentile figures illustrate that most readings cluster toward the lower end of each range, but occasional higher spikes are present.

Because only four stations contribute data, conditions can differ between neighbourhoods and times not captured by these rows. The freshness of the dataset is mixed: three pollutants (NO₂, PM₁₀, PM₂.₅, O₃) have been updated within the last few days, whereas NO relies on older information from more than a year ago. Users should therefore treat the presented values as snapshots that reflect recent conditions at specific sites rather than a comprehensive, city‑wide picture.

Data notes

The data shown are based on four valid measurements and were updated within 3 days, with the latest reading recorded at 2026‑02‑10T18:00:00+00:00. These values provide a snapshot of current conditions but air quality can differ across neighbourhoods and change throughout the day, so local variations may not be reflected in this summary.
