Air quality today

The air quality in Saarbrücken today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 1.93 and a PM10 reference value of 4.86, based on ten valid observations collected via OpenAQ.

This assessment reflects the current monitoring data for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Saarbrücken currently contains measurements for seven pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). These values come from 18 individual rows collected at four monitoring stations across the city, giving a modest spatial picture of air quality.

Most of the recent data were recorded on 2026‑02‑10 at 17:00 UTC, with CO, O₃, NO₂, PM₁₀, SO₂ and PM₂.5 all refreshed within the last three days. The only older entry is for NO, which dates back to 2024‑03‑11 at 11:00 UTC and is flagged as “old data”. Across the pollutants, the observed ranges are fairly narrow: CO is consistently reported at 320 µg/m³, while SO₂ varies between 1.07 and 2.20 µg/m³ and PM₁₀ spans 3.63 to 12.33 µg/m³. NO₂ shows a broader spread from 6.76 up to 19.55 µg/m³, with a median of about 8.79 µg/m³; O₃ ranges from roughly 30 to 63 µg/m³, median 59.6 µg/m³. The single‑point values for CO and PM₂.5 (both at 320 µg/m³ and 1.93 µg/m³ respectively) indicate limited temporal variation in the current sample.

Because the coverage includes only four stations and a handful of recent rows, the picture is incomplete and may not capture short‑term spikes or neighbourhood differences. Users should keep in mind that conditions can differ across Saarbrücken and that some pollutants, notably NO, rely on older measurements, so the dataset reflects a snapshot rather than a continuous real‑time view.

Data notes

The data shown for Saarbrücken is based on ten valid measurements and was 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 neighborhoods and moments throughout the day, so values may differ from what you experience locally.
