What the data includes

The Siesbach air‑quality record draws on two monitoring stations, each providing a single row of data for the five pollutants tracked in the OpenAQ feed: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and sulphur dioxide (SO₂). All measurements are expressed in micrograms per cubic metre. The most recent update across the dataset is from 2026‑02‑10 18:00 UTC, which applies to NO₂, O₃, PM₁₀ and SO₂; the NO value is older, last refreshed on 2024‑03‑11 11:00 UTC.

Across the two stations the observed concentrations span a modest range. NO stays at a single reported level of about 1 µg/m³, while NO₂ varies between roughly 4.3 and 5.5 µg/m³ with a median near 4.9 µg/m³. Ozone shows a broader spread from 55.1 up to 65.6 µg/m³, median around 60.4 µg/m³. PM₁₀ ranges from the detection limit of 1.0 µg/m³ to 14.7 µg/m³, with a median close to 7.8 µg/m³, indicating occasional higher particulate events. SO₂ is essentially constant at about 1.000125 µg/m³ across its narrow interval.

The dataset contains four rows classified as “old” (data older than three days) and six rows marked as recent, meaning that most of the available measurements are up‑to‑date while a small portion—particularly the NO reading—is dated by more than two years. Because only two stations contribute, spatial coverage within Siesbach is limited; conditions can differ in parts of the city not directly represented by these sensors. Nonetheless, the current snapshot provides a clear picture of the measured pollutants and their recent variability.
