The air quality in Valmadrera today is classified as Good. The primary pollutant identified for the current assessment is PM10, which refers to coarser particulate matter.
Three valid measurements were recorded, and the reported PM10 concentration is 37.19 µg/m³. This figure reflects the data shown via OpenAQ for this location on the measurement date. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The Valmadrera air‑quality dataset contains three measured pollutants – nitrogen dioxide (NO₂), ozone (O₃) and particulate matter up to 10 µm (PM10) – all reported from a single monitoring station. In total, the data set comprises three rows, one for each pollutant, so coverage is limited to this lone location within the city.
All of the latest readings were recorded on 2026‑02‑08 at 19:00 UTC, which falls well inside the “updated within 7 days” freshness window. For NO₂ the single value is 27.5511227 µg/m³; O₃ registers 25.23611 µg/m³; and PM10 shows 37.19 µg/m³. Because each pollutant has only one observation, the minimum, median and maximum are identical, giving a perfectly flat statistical profile with no spread to describe variability over time or across sites.
With just one station feeding data for all three compounds, the picture of Valmadrera’s air quality is necessarily narrow in both space and time. The dataset does not contain older or unknown‑age entries, but the lack of multiple monitoring points means that conditions elsewhere in the city may differ from those captured at this single site. Consequently, while the current numbers are recent and uniformly reported, they represent a snapshot rather than a comprehensive view of ambient air quality across Valmadrera.
