What the data includes
The dataset for Knittelfeld includes three measured pollutants – nitrogen dioxide (NO2), particulate matter up to 10 µm (PM10) and sulphur dioxide (SO2). Data come from eight recorded rows that originate from two monitoring stations. Two of the rows have been updated within the last three days, while the remaining six rows are classified as old. The most recent timestamps are 2026‑02‑10 20:00 UTC for both NO2 and PM10, and 2022‑05‑01 23:00 UTC for SO2.
Across the available records the observed concentrations span a wide interval. NO2 values range from a minimum of –1.0 µg/m³ (a placeholder) up to 60.0 µg/m³, with a median of 20.26775 µg/m³; the 10th percentile sits at about 3.25 µg/m³ and the 90th percentile near 52.05 µg/m³. PM10 shows a minimum of –1.0 µg/m³ and a maximum of 29.19345 µg/m³, median 15.0 µg/m³, with the 10th and 90th percentiles at roughly 2.2 µg/m³ and 26.35 µg/m³ respectively. SO2 values are lower overall, ranging from 2.0 µg/m³ to 13.20600795 µg/m³, median 7.603003975 µg/m³, and a tighter spread between the 10th percentile (3.12 µg/m³) and the 90th percentile (12.09 µg/m³).
The coverage is uneven: NO2 and PM10 are both reported from the Freiheitsallee station, while SO2 comes from the Parkstraße station, leaving parts of the city without concurrent measurements. Moreover, the predominance of old rows (six out of eight) means that recent conditions are captured only for the two most current entries, so the picture of air quality can vary noticeably by location and time.
