What the data includes

The dataset for Osnabrück contains measurements for carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). In total 11 rows of data are recorded across two monitoring stations, with each pollutant represented by at least one recent entry.

The most up‑to‑date values were logged on 2026-02-10 at 17:00 UTC for NO₂ (45.0885 µg/m³), PM₁₀ (23.362299 µg/m³), PM₂.₅ (11.6034 µg/m³) and CO (566.408 µg/m³). O₃ was last reported on 2026-02-10 at 17:00 UTC (38.132103 µg/m³) and SO₂ on 2026-02-10 at 10:00 UTC (0.031051 µg/m³). The only older entry is for NO, recorded on 2024-03-11 at 11:00 UTC with a maximum of 185.378998 µg/m³; all other pollutants have fresh timestamps within the past three days.

Across the pollutants the observed ranges vary considerably. NO shows a wide spread from a minimum of 1.58814 µg/m³ to a peak of 185.378998 µg/m³, while its median sits at 93.483569 µg/m³. In contrast, PM₂.5 values are tightly clustered between 10.4075 and 11.6034 µg/m³ with a median of 11.00545 µg/m³, indicating little variability in the recent measurements. CO is reported as a single constant value (566.408 µg/m³) because only one row is available for that pollutant.

Overall the data set provides a fairly current snapshot for most pollutants, but coverage is uneven: NO relies on an older record, and the number of rows per pollutant differs, meaning city‑wide conditions may still vary by location and time beyond what these limited entries capture.
