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 air‑quality record for Saint‑Nazaire‑le‑Désert currently draws on five measurement rows supplied by a single monitoring station. All five standard pollutants tracked by OpenAQ are present: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀) and particulate matter ≤ 2.5 µm (PM₂.₅). For each pollutant the dataset contains a single value, so the minimum, median and maximum are identical, giving a very narrow statistical spread.
The most recent data points were recorded on 2026‑02‑10 at 15:00 UTC for NO₂, O₃, PM₁₀ and PM₂.₅, which means those four pollutants have been updated within the last three days. The NO measurement is older, with its latest entry dated 2024‑03‑11 at 09:00 UTC, so it is almost two years out of date compared with the others. Because only one station contributes data, there is no geographic variation captured across the city; conditions can differ in other neighbourhoods or at different times of day.
Numerically, the recorded concentrations are very low: NO sits at 1.7 µg/m³, NO₂ at 0.6 µg/m³, O₃ at 58.9 µg/m³, PM₁₀ at 2.6 µg/m³ and PM₂.₅ at 1.6 µg/m³. The uniformity of the values (each pollutant has a single reading) means there is no observable range or trend within this dataset. Overall, the coverage is limited to one monitoring point with five rows of data, and while most pollutants are refreshed daily, the NO record remains outdated, highlighting that the picture presented here represents only a snapshot rather than a comprehensive view of air quality throughout Saint‑Nazaire‑le‑Désert.

Data notes
The data shown for Saint‑Nazaire‑le‑Désert is based on four valid measurements and was updated within three days, with the latest refresh recorded at 2026‑02‑10 15:00 UTC. These values provide a recent snapshot of ambient conditions, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be fully captured in this summary.
