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 Périgueux includes five measured 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 two monitoring rows, giving a very limited spatial coverage across the city.

The most recent observations are from 2026‑02‑10 15:00 UTC for NO₂, O₃, PM10 and PM2.5, while the NO reading is older, last updated on 2024‑03‑11 07:00 UTC. This means that four of the five pollutants have data refreshed within the past three days, but nitrogen monoxide relies on information that is almost two years old.

Across the available records, concentrations show a modest spread. For NO the values range from 0.0 to 8.7 µg/m³ with a median of 4.35 µg/m³; NO₂ varies between 5.4 and 15.3 µg/m³ (median 10.35 µg/m³); O₃ spans 7.0‑45.0 µg/m³ (median 26.0 µg/m³); PM10 ranges from 1.2 to 8.7 µg/m³ (median 4.95 µg/m³); and PM2.5 is recorded between 0.6 and 7.4 µg/m³ (median 4.0 µg/m³). The 10th‑percentile values are close to the minima for each pollutant, while the 90th‑percentile values sit near the maxima, indicating that most measurements cluster toward the lower end of the observed ranges.

Because only two rows contribute data, the picture presented here reflects a very narrow slice of Périgueux’s air quality. Conditions can differ across neighborhoods and over time, especially for NO where the latest reading is dated 2024‑03‑11. Users should keep in mind that the dataset provides limited spatial detail and that freshness varies between pollutants.

Data notes

The current dataset for Périgueux includes four valid measurements and was updated within three days, with the latest refresh recorded at 2026‑02‑10T15:00:00+00:00. These values represent a snapshot of conditions across the monitoring network; air quality can differ by specific location and time of day within the city, so individual experiences may vary from the reported figures.
