What the data includes

The air‑quality feed for Joué-lès‑Tours currently includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), fine particulate matter (PM₂.₅) and coarse particulate matter (PM₁₀). The dataset is built from eight individual rows that originate from two monitoring stations in the city, so each pollutant is not necessarily represented by the same number of observations.

All pollutants except NO have recent measurements dated 2026‑02‑10 15:00 UTC, which means their latest values were recorded within the past three days. NO’s most recent entry is older, from 2024‑03‑11 09:00 UTC, so its data are considerably less current than the others. The range of observed concentrations varies markedly across the suite: NO₂ spans from 4.6 to 5.48 µg/m³ with a median of about 5.0 µg/m³; O₃ ranges between 53.8 and 79.75 µg/m³, centred around a median of 66.8 µg/m³; PM₂.5 is recorded from 1.5 up to 8.7 µg/m³ with a median near 5.1 µg/m³; NO shows a single value of 2.4 µg/m³; and PM₁₀ is reported at a constant 2.2 µg/m³ across its row. The percentile spread (10th‑90th) highlights that most recent NO₂ values sit between roughly 4.7 and 5.4 µg/m³, while O₃ typically falls between about 56 and 77 µg/m³, indicating relatively tight clustering for these gases.

Because the dataset contains only two stations, spatial coverage across Joué-lès‑Tours is limited; conditions can differ in neighborhoods that are not directly sampled. Moreover, the older NO record means that any assessment of nitrogen monoxide must be treated with caution until newer observations become available.

Data notes

The current dataset for Joué‑lès‑Tours 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 recent snapshot of ambient conditions but may not capture short‑term fluctuations or micro‑scale differences across neighbourhoods. Consequently, air quality can vary by location and time within the city, so this overview should be interpreted as indicative rather than exhaustive.
