Air quality today

The air quality in Sotteville‑lès‑Rouen is assessed as Good today. The main pollutant identified is PM2.5, with a reference value of 1.6 µg/m³, while the PM10 reference value stands at 2.7 µg/m³ based on four valid measurements.

Data are shown via OpenAQ and reflect the current monitoring results for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality record for Sotteville-lès‑Rouen includes six measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulphur dioxide (SO₂). The dataset comprises 11 individual rows drawn from two monitoring stations, giving a modest spatial coverage of the city.

The most recent observations are fairly fresh for five of the pollutants, with data updated on 2026‑02‑10 at 15:00 UTC for NO₂, O₃, PM₁₀ and PM₂.₅, while the NO reading dates back to 2024‑03‑11 at 09:00 UTC. In contrast, the SO₂ measurement is considerably older, recorded on 2018‑01‑17 at 00:00 UTC. Overall, four of the eleven rows are from the last three days, seven are classified as “old” and none are unknown, indicating that a majority of the available data are not current.

Across the pollutants, the observed values span a wide range. NO varies between 4.0 and 26.2 µg/m³ with a median of about 15 µg/m³; NO₂ ranges from 16.9 to 30.2 µg/m³ (median ≈ 23.5 µg/m³); O₃ shows the greatest spread, from 1.1 up to 62.8 µg/m³ (median ≈ 32 µg/m³). Particulate matter levels are lower, with PM₁₀ between 2.7 and 15.2 µg/m³ (median ≈ 9 µg/m³) and PM₂.₅ from 1.6 to 9.8 µg/m³ (median ≈ 5.7 µg/m³). The single SO₂ reading is constant at 1.33 µg/m³.

These figures illustrate that while the city’s monitoring network captures a full suite of key pollutants, the data are unevenly distributed in time and concentration range. Recent measurements are available for most gases and particulates, but the older SO₂ record means current sulphur dioxide conditions cannot be assessed from this dataset alone, and overall air‑quality conditions may differ across neighbourhoods and moments not represented here.
