Latest sensor values
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 Bayreuth air‑quality record draws from a single monitoring site at Hohenzollernring, giving one data row for each of the four measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂) and particulate matter 10 µm or smaller (PM₁₀). Because there is only one station, the dataset does not capture spatial variation across the city; conditions at other neighborhoods may differ from those reported here.
The timestamps show a mixed picture of freshness. The most recent NO₂ and PM₁₀ values were updated on 2026‑02‑10 17:00 UTC, so these two pollutants have data that is current within the last three days. In contrast, the CO reading dates back to 2017‑12‑31 16:00 UTC and is flagged as “old data,” while the NO measurement was last refreshed on 2024‑03‑11 11:00 UTC. Overall, two of the four rows are recent, one is several years old, and none are marked as unknown or missing.
All four pollutants have a single recorded value, which also serves as their minimum, median and maximum because each series contains only one observation. CO registers at 390.0 µg/m³, NO at 8.55 µg/m³, NO₂ at 20.64 µg/m³ and PM₁₀ at 24.38 µg/m³. The lack of multiple measurements means there is no observable spread or percentile range for any pollutant; the dataset therefore provides a snapshot rather than a distribution. Because most rows are old or limited to one station, users should keep in mind that air‑quality conditions can vary across Bayreuth and over time, and the figures presented represent only the specific moments captured at Hohenzollernring.
