Latest sensor values
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 dataset for Le Puy‑en‑Velay contains measurements for four common air pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter up to 10 µm (PM₁₀). All values come from a single monitoring site, Le Puy‑Causans, so the city’s overall coverage is limited to one location. The most recent records show that NO₂ and O₃ were last updated on 2026‑02‑10 at 15:00 UTC, while PM₁₀ was refreshed on 2026‑02‑09 at 03:00 UTC. The NO reading is older, dated 2024‑03‑11 at 09:00 UTC, making it the least current datum in the set.
Each pollutant has only one reported figure, so there is no observed range or variability within the data. For NO the value is 1.6 µg/m³; for NO₂ it is 2.1 µg/m³; O₃ registers at 70.1 µg/m³; and PM₁₀ measures 6.7 µg/m³. Because the minimum, median and maximum are identical for every pollutant, the dataset reflects a single snapshot rather than a distribution of measurements over time.
Overall, the data are fairly fresh for three of the four pollutants, with updates within the past few days, but the older NO entry highlights that not all parameters are refreshed equally. With only one monitoring station contributing, conditions in other parts of Le Puy‑en‑Velay may differ from these point measurements, and the limited temporal depth means trends cannot be inferred from this snapshot alone.
