What the data includes

The dataset for Nancy in Grand Est 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 µg (PM₂.₅) and sulphur dioxide (SO₂). These values come from 15 individual rows recorded at four monitoring stations, the most frequently used being the Nancy‑Charles III site.

The newest data points were collected on 2026-02-10 15:00 UTC for NO₂, PM₂.₅, O₃, PM₁₀ and SO₂, showing that half of the pollutants have very recent updates. In contrast, the NO measurement is older, last refreshed on 2024-03-11 08:00 UTC, while CO is based on a single record from 2019-08-09 11:00 UTC, indicating uneven temporal coverage across the suite of gases. Typical concentrations are modest: the median NO value is 24.7 µg/m³ with observed values ranging from 20.7 to 37.1 µg/m³; NO₂ shows a median of 11.9 µg/m³ and spans 9.6 to 39.7 µg/m³. PM₂.₅ is consistently low, with a minimum of 1.0 µg/m³ (the same as the current reading) and a maximum of 11.1 µg/m³, while PM₁₀, O₃ and SO₂ each have a single reported value – 5.1 µg/m³, 53.3 µg/m³ and 0.6 µg/m³ respectively – all recorded on the same recent date.

Because many rows are dated or limited to a single observation, the picture of air quality in Nancy is incomplete and can vary considerably across locations and times. Users should keep in mind that the available data represent only the moments captured at the listed stations and may not reflect current conditions throughout the whole city.
