What the data includes

The air‑quality record for Orléans currently 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). Data come from 13 individual rows, of which four are associated with the most recent reporting period; the remaining nine rows are older observations.

The freshest measurements were all taken on 2026‑02‑10 at 15:00 UTC for NO₂, PM₁₀, O₃ and PM₂.5, while the latest NO value dates back to 2024‑03‑11 at 09:00 UTC. Across the recent set, NO₂ ranges from a low of 2.1 µg/m³ to a high of 20.6 µg/m³ with a median around 9.5 µg/m³; PM₁₀ spans 4.1‑19.9 µg/m³ (median ≈ 14.1 µg/m³); O₃ is relatively tight between 69.4 and 77.3 µg/m³ (median ≈ 73.3 µg/m³). PM₂.5 shows a single recorded value of 3.0 µg/m³, indicating only one recent observation for this fine fraction. NO, based on the older data point, varies from 3.3 to 25.9 µg/m³ with a median near 14.6 µg/m³.

These figures reveal that most pollutants have several recent entries, but coverage is uneven: PM₂.5 and NO rely on very limited or dated rows, so city‑wide conditions for those components may be less well represented. Overall, the dataset provides a snapshot of current air quality in Orléans, yet the variation in timestamp recency and row count means that spatial and temporal nuances could differ across the city.
