What the data includes

The dataset for the Stadtgebiet Bremen covers 42 individual measurement rows drawn from 8 monitoring stations and includes readings 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 sulfur dioxide (SO₂). Across the whole set, 31 rows have been updated within the last three days while 11 rows are older; no entries are marked as unknown or from today’s date.

For most pollutants the newest observations were recorded on 2026‑02‑10 18:00 UTC. The latest CO value is 420.0 µg/m³ measured at Bremen‑Mitte, NO₂ stands at 23.46 µg/m³ and O₃ at 29.19 µg/m³ both from the Bremen‑Ost station, PM₁₀ reaches 32.71 µg/m³ and PM₂.₅ 13.2 µg/m³ also at Bremen‑Ost, while SO₂ is 0.91 µg/m³ at Bremen‑Nord. The only older timestamp belongs to NO, recorded on 2024‑03‑11 11:00 UTC with a value of 7.82 µg/m³ from Bremen‑Hasenbüren.

The observed ranges show considerable variability: CO spans from 330 to 920 µg/m³, NO₂ varies between 20.71 and 65.98 µg/m³, and PM₁₀ runs from 12.61 to 43.43 µg/m³. Median values tend to sit near the middle of these spreads – for example, the median CO is 410 µg/m³ while the median NO₂ is 25.87 µg/m³ – indicating that extreme highs are relatively infrequent but present. Coverage is uneven across pollutants; eight stations contribute data for CO, PM₁₀ and O₃, whereas only five stations report NO and six provide SO₂ measurements. Because a portion of the rows (about one‑quarter) are older than three days, the snapshot reflects recent conditions in many locations but may miss short‑term fluctuations elsewhere in the city.
