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
Grandfontaine’s OpenAQ feed currently provides data for five measured pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). All of these values come from a single monitoring station, so the dataset contains one row per pollutant.
The most recent measurements are fairly up‑to‑date for four of the pollutants, with the last update recorded on 2026-02-10 15:00 UTC. The NO reading is older, dated 2024-03-08 15:00 UTC, and is flagged as “Old data”. For each pollutant the reported value is identical across minimum, median and maximum, indicating that only a single observation is available at this time. NO registers 0.8 µg/m³, NO₂ 1.6 µg/m³, O₃ 67.8 µg/m³, PM₁₀ 0.8 µg/m³ and PM₂.₅ 0.5 µg/m³, all measured at the Donon Vosges Moyennes 2 site.
Because the dataset consists of a single station, spatial coverage across Grandfontaine is limited; conditions elsewhere in the city may differ from those captured here. The uniformity of the values (no spread between minimum and maximum) reflects the lack of multiple observations rather than stability in the atmosphere. Additionally, the older NO record shows that not all pollutants are refreshed with the same frequency, so users should be aware that the freshest snapshot for most pollutants is from early February 2026, while the nitrogen monoxide reading is nearly two years older.
