What the data includes
The data set for Sesto San Giovanni includes three measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂) and fine particulate matter (PM2.5). Each pollutant is represented by a single monitoring row, all coming from the SESTO S.GIOVANNI station. Because there is only one row per contaminant, the reported minimum, median and maximum values are identical for each metric.
All three readings are recent: the CO and NO₂ values were last updated on 2026‑02‑04 at 07:00 UTC, while the PM2.5 measurement was refreshed earlier that same day at 00:00 UTC. The freshness flag indicates that every datum has been updated within the past 30 days, so the information reflects the most current conditions captured by this station.
The CO concentration is recorded as 579.95 µg/m³, NO₂ as 61.13 µg/m³ and PM2.5 as 16.8 µg/m³. Because each pollutant has only one observation, there is no spread to describe – the range for every metric collapses to a single point. This limited coverage means that while the data are up‑to‑date, they represent conditions at a specific location and time rather than a citywide average. Consequently, air quality in other parts of Sesto San Giovanni may differ from what these values show.
