What the data includes

The Busto Arsizio 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 of these values come from a single monitoring station, giving a total of five data rows. Because the coverage is limited to one location, the figures represent conditions at that specific site rather than a city‑wide average.

The timestamps show mixed freshness across the pollutants. The CO reading is dated 2024‑03‑11 10:00 UTC, which classifies it as older data, while the NO₂, O₃ and SO₂ values were all recorded on 2026‑02‑07 20:00 UTC and the PM10 measurement on 2026‑02‑09 03:00 UTC. The latter three timestamps fall within the last seven days, indicating that most of the recent data are up to date, but the carbon‑monoxide figure lags behind by almost two years.

Because each pollutant has only one recorded value, the statistical spread is essentially zero – the minimum, median and maximum are identical for every metric. CO registers 582.38 µg/m³, NO₂ 41.18284 µg/m³, O₃ 2.9756 µg/m³, PM10 49.59 µg/m³ and SO₂ 2.558689 µg/m³. This lack of variability means the dataset cannot show short‑term fluctuations or trends for Busto Arsizio; it simply provides a snapshot from each pollutant at the times listed. Users should keep in mind that air quality can differ across neighborhoods and over time, especially when only one monitoring point contributes data.

Data notes

The data for Busto Arsizio are based on four valid measurements and were refreshed recently, being updated within three days (last update: 2026‑02‑09T03:00:00+00:00). This snapshot reflects conditions at the time of collection; however, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
