What the data includes
The dataset for Sarezzo contains four pollutant measurements – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter ≤10 µm (PM10) – each recorded at a single monitoring location, giving a total of four data rows. The CO value is 480.688 µg/m³ and its most recent entry dates back to 2022‑03‑14 08:00 UTC, which makes it the oldest record in the set. By contrast, the NO₂ (21.16009 µg/m³), O₃ (15.2119436 µg/m³) and PM10 (37.332222 µg/m³) readings were all logged within the last week, on 2026‑02‑09 03:00 UTC for NO₂ and 2026‑02‑08 19:00 UTC for O₃ and PM10, indicating fresh data for three of the four pollutants.
All four measurements share a single observed value – the minimum, median and maximum are identical for each pollutant – which reflects that only one recent observation is available per parameter. Consequently, there is no statistical spread to describe variability over time; the dataset provides a snapshot rather than a range of conditions. The presence of an “old” flag for the CO row highlights uneven temporal coverage: while NO₂, O₃ and PM10 are up‑to‑date, the CO data has not been refreshed for more than three years.
Because the city’s air quality information relies on just one monitoring site, spatial differences across Sarezzo cannot be captured in this collection. Users should keep in mind that conditions may differ elsewhere in the municipality or change throughout the day, and that the current dataset offers a limited, point‑in‑time view of each pollutant.
