What the data includes

The air‑quality record for Bolzano – Bozen includes six monitoring sites that together provide twenty recent observations across the six measured pollutants: carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and sulphur dioxide (SO₂). The freshest data are from 2026‑02‑07 09:00 UTC for NO₂, O₃, SO₂, CO and PM₁₀, while the most recent NO reading dates back to 2024‑03‑11 10:00 UTC.

Across the dataset the concentration ranges vary markedly. NO values span from a low of 19.51 µg/m³ at BZ4 (the only recent entry) up to a maximum of 165.30 µg/m³, with a median around 36.21 µg/m³, indicating considerable variability in nitrogen oxide levels at that site. NO₂ shows a tighter spread, ranging between 27.54 and 84.85 µg/m³, median 47.75 µg/m³, and the example reading of 31.41 µg/m³ at BZ4 falls near the lower‑quartile end of that distribution. Ozone concentrations are uniformly low, all between 1.88 and 2.22 µg/m³ with a median of 2.05 µg/m³; the recorded value of 1.88 µg/m³ at BZ6 represents the minimum observed level. SO₂ values cluster tightly around 1.12–1.25 µg/m³ (median 1.19 µg/m³), with the highest reading of 1.25 µg/m³ also from BZ6. CO measurements are higher, ranging from 450 to 650 µg/m³ (median 550 µg/m³); the peak value of 650 µg/m³ at BZ5 is the upper bound of that range. PM₁₀ shows the narrowest band, from 19.47 to 24.23 µg/m³ (median 21.85 µg/m³), with the lowest observed concentration of 19.47 µg/m³ at BZ5.

Overall, the dataset offers recent information for five of the six pollutants, but NO data are older than two years, limiting a fully up‑to‑date picture for that gas. The number of stations is modest, so conditions can differ across neighborhoods and times not captured by these rows.

Data notes

The data shown are based on six valid measurements and have been updated within 7 days, with the latest refresh recorded at 2026‑02‑07T09:00:00+00:00. These values provide a snapshot of current conditions but air quality can differ across neighborhoods and change throughout the day, so local variations may not be fully captured in this overview.
