Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The Pioltello air‑quality dataset contains measurements for five common pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂, written as NO2), ozone (O₃, written as O3), particulate matter up to 10 µm (PM10) and sulfur dioxide (SO₂). All data come from a single monitoring station, so the coverage is limited to one location within the city.
The most recent values are fairly recent for four of the pollutants, with NO2, O3, PM10 all last updated on 2026‑02‑07 at 20:00 UTC and CO recorded on 2022‑03‑14 at 08:00 UTC. SO₂ is older, dated 2024‑03‑11 at 10:00 UTC. Each pollutant shows a single reported value, meaning there is no observed spread in the data: CO is consistently 468.633 µg/m³, NO2 stays at 47.01953 µg/m³, O3 at 1.165416 µg/m³, PM10 at 31.4 µg/m³ and SO₂ at 2.989449 µg/m³. The median, minimum and maximum for every pollutant are identical, indicating that only one measurement per parameter is currently available.
Because the dataset consists of just one row, there is no variation across different sites or times within Pioltello. This limited spatial and temporal coverage means the figures represent a snapshot rather than a comprehensive picture of city‑wide air quality; conditions can differ in other neighborhoods or at other moments. The freshness of most data points (within the last week) suggests that recent monitoring is ongoing for NO2, O3 and PM10, while CO and SO₂ rely on older records.
