Air quality today

The air quality in Monza today is classified as USG. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 45.0 and a PM10 reference value of 50.1, based on eight valid observations recorded by OpenAQ.

Data are presented without interpretation or recommendation. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Monza air‑quality dataset currently contains observations from two monitoring sites, giving a total of eight individual rows of data. Five pollutants are reported: nitrogen dioxide (NO2), ozone (O3), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulfur dioxide (SO2). All measurements were recorded within the last week, with the most recent timestamps on 2026‑02‑08 at 19:00 UTC for PM10 and PM2.5, and at 17:00 UTC for NO2, O3 and SO2.

The values show a fairly wide spread for the gases and coarse particles. NO2 ranges from about 11 µg/m³ up to 34 µg/m³, with a median near 23 µg/m³; ozone varies between roughly 5 µg/m³ and 43 µg/m³, median around 24 µg/m³. PM10 values are between 25 µg/m³ and 50 µg/m³, median 38 µg/m³, while the single PM2.5 reading is consistently 45 µg/m³ across its sole row. Sulfur dioxide appears at a constant level of about 1.9 µg/m³ in its only entry.

Coverage differs among pollutants: NO2, O3 and SO2 each have two recent rows, whereas PM10 also has two, but PM2.5 is represented by just one row. Because the dataset relies on a limited number of stations, conditions can differ across neighborhoods and times not captured here. The overall freshness—all data logged within the past seven days—means the figures reflect the most current snapshot available for Monza, though the small sample size should be kept in mind when interpreting city‑wide air quality.
