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
Maddaloni’s air‑quality feed currently includes four measured pollutants – nitrogen dioxide (NO2), ozone (O3), particulate matter up to 10 µm (PM10) and fine particulate matter up to 2.5 µm (PM2.5). All of these values come from a single monitoring location, identified as CE54 SCUOLA SETTEMBRINI, so the dataset consists of four rows in total. Each pollutant has one recorded value that is both the minimum, median and maximum for its series, indicating no variation within the available data.
The most recent update for every parameter was logged on 2026‑02‑07 at 07:00 UTC, and each entry carries a “Updated within 7 days” flag. This means the freshest information for Maddaloni is less than a week old, but there are no older or unknown timestamps to provide a longer historical context. Because all four pollutants share the same timestamp, the dataset does not reveal any temporal spread; the snapshot reflects conditions at a single moment rather than a range over days.
Given that only one station contributes data, the figures represent conditions at that specific site and may not capture spatial differences across the wider city area. The recorded concentrations are 10.33 µg/m³ for NO2, 24.82 µg/m³ for O3, 29.29 µg/m³ for PM10 and 12.25 µg/m³ for PM2.5. With identical min‑median‑max values, the dataset shows a very narrow numeric spread, which limits insight into variability or trends. Users should keep in mind that air quality can change across neighborhoods and over time, and the current snapshot provides only a limited view of Maddaloni’s overall atmospheric conditions.

Data notes
The data shown for Maddaloni is based on four valid measurements and was refreshed recently, Updated within 7 days (last update: 2026‑02‑07T07:00:00+00:00). These readings provide a snapshot of current conditions but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
