Air quality today

The air quality in Vercelli today is classified as Moderate. The primary pollutant measured is PM2.5 (fine particles). Data from OpenAQ shows a PM2.5 reference value of 15.0 and a PM10 reference value of 49.0, based on five valid measurements.

These figures reflect the current monitoring snapshot for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Vercelli currently contains measurements for four pollutants – nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀) and particulate matter ≤2.5 µm (PM₂.₅). In total there are five observation rows, but only two of them have been updated within the last seven days; the remaining three rows are older or lack a recent timestamp. The most up‑to‑date values were recorded on 2026‑02‑07 at 09:00 UTC for NO₂ (22 µg/m³) and O₃ (7 µg/m³), while PM₁₀ and PM₂.₅ were last refreshed on the same day at 07:00 UTC with values of 49 µg/m³ and 15 µg/m³ respectively.

All four pollutants are represented by a single monitoring site each, so spatial coverage across the city is limited to those specific locations – Gastaldi for NO₂, PM₁₀ and PM₂.₅, and CONI for O₃. Because there is only one row per pollutant, the reported minimum, median and maximum values are identical (e.g., NO₂ consistently reads 22 µg/m³). This lack of variation means the dataset does not capture any intra‑city differences or short‑term fluctuations.

Overall, the data set shows a modest level of freshness: two recent updates within the past week, but three rows remain older than seven days. Consequently, while the current figures give a snapshot of pollutant concentrations at the listed stations, they do not reflect broader temporal trends or conditions in other parts of Vercelli. Users should keep in mind that air quality can change across neighborhoods and over time, and the available data provides only a limited view of the city’s overall environment.
