What the data includes

The dataset for Azuqueca de Henares contains five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 2.5 (PM₂.5) and sulphur dioxide (SO₂). All values come from a single monitoring location identified as “AZUQUECA - IES”, so the station count is one row per pollutant, giving a total of twelve recorded rows across all parameters. The most recent measurements are from 2026‑02‑09 15:00 UTC for NO₂, O₃ and SO₂, while PM₂.5 was last updated on 2026‑02‑09 09:00 UTC. Only the NO reading is older, dated 2024‑02‑13 00:00 UTC, which the system flags as old data.

Across the recent data the observed ranges are modest. NO₂ varies between 16 and 47 µg/m³ with a median of 17 µg/m³; O₃ spans 3 to 51 µg/m³, centred around a median of 49 µg/m³; SO₂ is tightly clustered at 3–4 µg/m³ with a median of 4 µg/m³; PM₂.5 shows a single value of 8 µg/m³; and NO remains constant at 6 µg/m³. The ten‑percentile values indicate that most recent NO₂ readings sit just above the minimum (≈16 µg/m³) while O₃’s ten‑percentile is around 12 µg/m³, suggesting a skew toward higher ozone concentrations in the latest sample set.

Because the dataset relies on a single site, spatial coverage across Azuqueca de Henares is limited. Although three pollutants have fresh updates within the past week, the older NO measurement and the uniformity of PM₂.5 and SO₂ values highlight gaps that could miss short‑term fluctuations elsewhere in the city. Users should keep in mind that conditions may differ by neighbourhood and time beyond what these few recent rows capture.
