What the data includes
The dataset for Cappelle‑la‑Grande pulls information from eleven measurement rows collected at two monitoring stations. It includes six pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). The timestamps show a mixed picture of freshness: the most recent entry is for PM₁₀ on 2026‑02‑09 03:00 UTC, while the other pollutants were last updated between March 2024 and January 2025, so only one pollutant has data from within the past week.
Across the available records, NO values range from 1.7 to 4.9 µg/m³ with a median of about 3.3 µg/m³, indicating relatively tight variation. NO₂ shows a broader spread, from 6.1 up to 29.4 µg/m³ and a median near 17.8 µg/m³. Ozone reaches a maximum of 28.0 µg/m³ (median 21.5 µg/m³), while SO₂ varies between –1.0 and 8.3 µg/m³, the negative minimum reflecting occasional sensor noise; its median sits at roughly 3.7 µg/m³. PM₁₀ values sit between 12.0 and 24.6 µg/m³ with a median of 18.3 µg/m³. For PM₂.₅ there is only a single historic reading from 2017‑12‑31 18:00 UTC at 2.65 µg/m³, so no range or recent trend can be derived.
Overall the coverage is uneven: while all six pollutants are listed, five of them rely on data that is several months to years old, and PM₂.₅ is represented by a lone outdated point. Consequently, the snapshot reflects past conditions rather than current air quality, and variations across the city at any given moment may differ from what these records show.
