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 Ottweiler air‑quality dataset contains four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter ≤ 10 µm (PM10). All values come from a single monitoring station, so the dataset comprises four rows in total. The most recent measurement for NO was recorded on 2024‑03‑11 11:00 UTC, while the other three pollutants have updates as recent as 2026‑02‑10 18:00 UTC, indicating that the latest data are only a few days old for NO₂, O₃ and PM10 but more than a year old for NO.
Each pollutant currently has a single reported value, which also serves as its minimum, median and maximum. NO is consistently measured at 17.85 µg/m³, NO₂ at 28.35 µg/m³, O₃ at 38.13 µg/m³ and PM10 at 6.23 µg/m³. Because there is no variation across the recorded period, the dataset does not show any spread or trend for these substances; the reported percentiles (10th and 90th) match the single value in each case.
The coverage is therefore limited: only one location contributes data, and each pollutant appears once. While the timestamps for three of the four pollutants are fairly fresh, the NO measurement is considerably older, which means that current conditions for nitrogen monoxide may not be reflected accurately. Users should keep in mind that air‑quality can differ across neighborhoods and over time, and the present snapshot represents a very narrow view of Ottweiler’s atmospheric composition.
