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 air‑quality record for Châtenois in Bourgogne – Franche‑Comté currently draws on two data rows collected from a single monitoring site. Both PM10 and SO₂ are reported, but each pollutant appears only once in the dataset, so the picture is limited to those individual measurements rather than a broader network of sensors.
The most recent PM10 reading shows a concentration of 8.9 µg/m³ recorded at 2026‑02‑09 03:00 UTC, while the latest SO₂ value is 1.7 µg/m³ logged on 2026‑02‑10 15:00 UTC. Because each pollutant has just one entry, the reported range for both is effectively a single point – the minimum, median and maximum are all identical (8.9 µg/m³ for PM10 and 1.7 µg/m³ for SO₂). This means there is no observed spread or variability in the data to describe typical fluctuations over time.
Freshness of the information is relatively good: both timestamps fall within a week of today’s date, satisfying the “updated within 7 days” criterion for PM10 and “updated within 3 days” for SO₂. However, with only one station contributing, the coverage is narrow; any changes in air quality across different neighborhoods or at other times of day are not captured by this dataset.
In summary, Châtenois offers data on two key pollutants, but the current snapshot consists of a single recent measurement per pollutant from one location. The values are consistent because there is no historical spread to compare against, and while the timestamps are up‑to‑date, the limited station count means the information reflects only a specific point in space and time rather than a comprehensive view of city‑wide conditions.
