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 dataset for Andoain includes five measured pollutants – nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10), fine particulate matter 2.5 µm or less (PM2.5) and sulfur dioxide (SO2). All of these come from a single monitoring station, so the city’s air‑quality picture is based on one row of data rather than a network of sites.
Each pollutant shows exactly the same value for its minimum, median and maximum because only one observation is available. NO2 registers at 41.0 µg/m³, O3 at 37.0 µg/m³, PM10 at 10.0 µg/m³, PM2.5 at 5.0 µg/m³ and SO2 at 3.0 µg/m³. The lack of spread means there is no internal variability to describe; the reported figure represents both the typical (median) level and the full observed range for the city on the date recorded.
The most recent timestamp across all pollutants is 2026‑02‑09 15:00 UTC, which falls within the “updated within 7 days” freshness bucket. Because every pollutant shares this same update time, the dataset as a whole can be considered current, but the single‑station coverage limits spatial detail – conditions may differ in other parts of Andoain or change throughout the day. Consequently, while the numbers give an up‑to‑date snapshot for the monitored location, they do not capture broader temporal or geographic variation within the city.
