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 Vaulx‑en‑Velin contains measurements of five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). All values come from a single monitoring station, giving a total of five rows of data.
The most recent observations are fairly fresh for three of the pollutants: NO₂ was recorded at 6.1 µg/m³ on 2026‑02‑10 15:00 UTC, O₃ at 67.1 µg/m³ on the same day and time, and PM2.5 at 18.6 µg/m³ on 2026‑02‑09 03:00 UTC. In contrast, the NO reading dates back to 2024‑01‑04 08:00 UTC (40.9 µg/m³) and the PM10 measurement is from 2022‑05‑02 12:00 UTC (13.7 µg/m³). This uneven timing means that while some pollutants reflect current conditions, others represent older snapshots.
Across the five rows the values are identical for each pollutant – there is no spread between minimum, median and maximum readings. For example, NO consistently registers 40.9 µg/m³, and PM10 remains at 13.7 µg/m³ wherever it appears. The lack of variation suggests that only a single point in the city is being sampled, so conditions elsewhere may differ.
Overall, the data set offers recent information for three key pollutants but relies on older measurements for NO and PM10. Users should keep in mind that the limited station coverage and mixed freshness mean the figures represent specific moments at one location rather than a comprehensive view of air quality throughout Vaulx‑en‑Velin.

Data notes
The data shown are based on three valid measurements and were updated within 3 days, with the latest reading recorded at 2026‑02‑10 15:00 UTC. These values represent a snapshot of air quality for Vaulx‑en‑Velin and may differ across neighborhoods or change throughout the day, so they should be interpreted as an approximate indication rather than a precise, city‑wide constant.
