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
Rehlingen‑Siersburg’s public air‑quality feed contains data for five key pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and sulphur dioxide (SO₂). All measurements come from a single monitoring location in the Biringen district, so the dataset comprises five rows – one for each pollutant – recorded at that site.
The timestamps show a mixed picture of data freshness. The most recent values for NO₂, O₃, PM₁₀ and SO₂ were all logged on 2026‑02‑10 at 18:00 UTC, meaning those four pollutants are updated within the last three days. In contrast, the NO reading is older, with its last update recorded on 2024‑03‑11 at 11:00 UTC, and it is flagged as “old data”. Because only one station contributes, there is no spatial variation captured across the city; conditions can differ in other neighborhoods or at different times of day.
All five pollutants show a single reported value that also serves as their minimum, median and maximum for the available period. NO registers 0.65 µg/m³, NO₂ 3.92 µg/m³, O₃ 59.92 µg/m³, PM₁₀ 2.35 µg/m³ and SO₂ 1.24 µg/m³. The lack of variability (identical min‑med‑max) indicates that the dataset reflects only a snapshot rather than a range of observations over time. Consequently, while the recent updates for most pollutants suggest timely reporting, the limited station coverage and the static nature of the values mean the data provide only a narrow view of air quality in Rehlingen‑Siersburg at the recorded moments.
