What the data includes

The Zellerndorf air‑quality feed contains six measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulphur dioxide (SO₂). Data come from 12 individual rows recorded at two monitoring stations, all of which are located in the Pillersdorf bei Retz area.

The most recent observations were taken on 2026‑02‑10 at 20:00 UTC for NO₂, O₃, PM₁₀, PM₂.₅ and SO₂, while the latest NO value dates back to 2024‑03‑11 at 12:00 UTC. Across the pollutants the recorded concentrations span modest ranges: NO varies from about 0.64 to 1.30 µg/m³ with a median near 0.97 µg/m³; NO₂ runs between 5.31 and 11.26 µg/m³, median 8.28 µg/m³; O₃ is observed from 32.83 up to 57.77 µg/m³, median 45.30 µg/m³; PM₁₀ ranges 10.01–26.08 µg/m³, median 18.04 µg/m³; PM₂.₅ lies between 18.83 and 22.44 µg/m³, median 20.63 µg/m³; SO₂ is measured from 0.61 to 2.25 µg/m³, median 1.43 µg/m³. For each pollutant the 10th‑percentile values are close to the minima and the 90th‑percentiles approach the maxima, indicating a relatively tight spread around typical levels.

Because only two stations supply all rows, spatial coverage within Zellerndorf is limited; conditions can differ in other neighbourhoods or at times not captured by these timestamps. The NO data are notably older than the others, so recent trends for that gas cannot be assessed from this set. Overall, the dataset provides a snapshot of current air quality but reflects modest temporal and geographic resolution.
