What the data includes

The dataset for Como includes six measured pollutants – carbon monoxide, nitrogen dioxide, ozone, PM10, PM2.5 and sulphur dioxide – all reported from a single monitoring location on Viale Cattaneo. Each pollutant has exactly one recorded value, so the minimum, median and maximum are identical: CO 898.24 µg/m³, NO₂ 51.73549 µg/m³, O₃ 7.857338 µg/m³, PM10 30.2 µg/m³, PM2.5 18.4 µg/m³ and SO₂ 1.675864 µg/m³. Because there is only one row per pollutant, the data show no internal spread; the reported figure represents the sole measurement available for that day.

All six readings were last updated on 2026-02-08 at 19:00 UTC, which falls within the “updated within 7 days” freshness category. This means the information is relatively current, but the coverage is limited to a single site, so conditions elsewhere in Como may differ from what the Viale Cattaneo sensor records.

In summary, the city’s air‑quality snapshot consists of one recent observation per pollutant from one station, providing a concise but geographically narrow view of ambient concentrations at a specific moment.
