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 Thônex air‑quality dataset contains three pollutant measurements – nitrogen dioxide, ozone and PM10 – all recorded at the single monitoring site identified as Thônex‑Foron. Each of the three rows in the data set is recent; the latest timestamp for every pollutant is 2026-02-10 16:00 UTC, which falls within the past seven days. Because there is only one reporting location, the dataset does not capture spatial variation across the municipality.
The values are identical across their statistical summaries, indicating no observed spread in this snapshot. Nitrogen dioxide registers at 10.042 µg/m³, ozone at 73.2346 µg/m³ and PM10 at 4.2 µg/m³; for each pollutant the minimum, median, maximum, as well as the 10th and 90th percentiles are the same as the single recorded value. This uniformity reflects the limited number of observations rather than a stable ambient condition.
Overall, the data set offers a very narrow view: three pollutants from one station, all updated within the last week, but without any range or variability to describe fluctuations over time or across different parts of Thônex. Consequently, while the figures provide an up‑to‑date snapshot for the specific site, they do not represent broader city‑wide air quality patterns.
