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 dataset for Saronno currently contains measurements for four key pollutants – nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10) and particulate matter 2.5 µm or less (PM2.5). All four values come from a single monitoring location, identified as SARONNO - SANTUARIO, so the city’s air‑quality picture is based on one station rather than a network of sites.
Each pollutant shows exactly the same timestamp: 2026-02-07 20:00 UTC, and every entry is flagged as “Updated within 7 days.” This means the most recent data are less than a week old, but there are no older or unknown‑age records in the set. Because each parameter has only one recorded value, the statistical spread is zero – the minimum, median, maximum, 10th percentile and 90th percentile are all identical (NO2 25.7071056 µg/m³, O3 4.228888 µg/m³, PM10 33.3 µg/m³, PM2.5 23.2 µg/m³). Consequently, the dataset cannot illustrate variability over time or across different parts of the city.
In practical terms, the information available for Saronno is limited to a snapshot from one site on a single day. While the data are fresh, the lack of multiple stations and repeated measurements means that short‑term fluctuations or neighborhood differences are not captured here. Users should keep in mind that conditions elsewhere in the municipality may differ from what this solitary point reports.

Data notes
The data for Saronno reflects four valid measurements and is marked as Updated within 7 days, with the latest values recorded on 2026‑02‑07 at 20:00 UTC.
