Air quality today

The air quality in Treviglio today is classified as USG. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 40.5 and a PM10 reference value of 50.7, based on eight valid observations.

Data are shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Treviglio air‑quality feed draws from two monitoring rows that together capture eight different variables: carbon monoxide (CO), nitrogen dioxide (NO2), fine particulate matter (PM1, PM2.5 and PM10), relative humidity, temperature, and particle concentration measured as UM003. The dataset is modest in size – only two rows of observations – but it provides a snapshot of the most recent conditions for each pollutant.

The freshest records were all logged on 2026‑02‑08 at 19:00 UTC for CO, NO2, PM2.5 and PM10, meaning those four parameters are up to date within the last week. The remaining four variables – PM1, relative humidity, temperature and UM003 – were last reported on 2026‑02‑05 at 09:00 UTC, which places them within the past month. Across all pollutants the median values are tightly clustered around the single measurements available: CO sits at 473.539 µg/m³, NO2 at 69.41492 µg/m³, PM2.5 averages 45.67 µg/m³ (with a range from 40.5 to 50.83 µg/m³), and PM10 is steady at 50.7 µg/m³. For the other four parameters the single readings give a median equal to the minimum and maximum – 30.18 µg/m³ for PM1, 57.21 % for relative humidity, 12.12 °C for temperature and 1550.84 particles/cm³ for UM003.

Because the dataset consists of only two rows, coverage is uneven: half of the pollutants have very recent updates, while the other half rely on data that are up to a month old. This limited temporal depth means the figures represent conditions at specific moments rather than continuous trends, and actual air quality in Treviglio can differ across neighborhoods and over time.

Data notes

The data shown for Treviglio reflects eight valid measurements and is Updated within 3 days, with the latest values recorded at 2026‑02‑08T19:00:00+00:00. This snapshot provides a current view of city‑wide air quality but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
