PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Passau contains measurements of five pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). In total nine rows of data are recorded across two monitoring stations, giving a modest spatial coverage that captures conditions at only a few points in the city.
The most recent observations were uploaded on 2026‑02‑10 20:00 UTC for CO, NO₂, PM₁₀, PM₂.₅ and on 2024‑03‑11 11:00 UTC for NO, so five of the six pollutant series are up‑to‑date within the last three days while the nitrogen oxide reading is older by almost two years. CO shows a single value of 550.0 µg/m³ at the Angerstraße site, indicating that only one measurement was available for this gas. NO ranges from 11.47 to 29.30 µg/m³ with a median of about 20.4 µg/m³ across two rows, while NO₂ varies between 32.28 and 38.30 µg/m³ (median ≈ 35.3). PM₁₀ spans 22.95 to 50.31 µg/m³ (median ≈ 36.6) and PM₂.5 covers 21.70 to 29.31 µg/m³ (median ≈ 25.5). The ten‑percentile values sit near the lower ends of each range, and the ninety‑percentile values approach the maxima, showing a fairly wide spread especially for NO and PM₁₀.
Because the data come from just two stations and some pollutants have only a single recent record, the picture they provide is limited. Conditions can differ across neighborhoods and over time, so these figures represent snapshots rather than a comprehensive view of air quality throughout Passau.

Data notes
The current overview for Passau is based on four valid measurements and was refreshed within the last three days, with the most recent data recorded at 2026‑02‑10 20:00 UTC. This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
