Air quality today
The air quality in Casirate d'Adda is classified as USG. The primary pollutant measured today is PM2.5, with a reference concentration of 40.0 µg/m³ and an accompanying PM10 reference value of 49.6 µg/m³ based on four valid observations.
Data are shown via OpenAQ and reflect the current assessment for this location. 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 air‑quality record for Casirate d’Adda currently draws on four sensor rows, one each for nitrogen dioxide, ozone, PM10 and PM2.5. All four pollutants are represented, so the dataset gives a complete snapshot of the main regulated substances tracked in the city. The most recent measurements were taken on 2026‑02‑07 at 20:00 UTC for NO₂ and on 2026‑02‑08 at 19:00 UTC for O₃, PM10 and PM2.5, meaning every value is less than eight days old and falls into the “updated within 7 days” freshness category.
Because each pollutant has only a single row, the reported figures show no internal spread: the minimum, median and maximum are identical for every substance. NO₂ registers at 31.2171173 µg/m³, O₃ at 34.975 µg/m³, PM10 at 49.6 µg/m³ and PM2.5 at 40.0 µg/m³. With a single observation per pollutant, the dataset cannot reveal variability over time or across locations within Casirate d’Adda; it simply reflects the latest point‑in‑time reading from each sensor.
Overall, the coverage is limited to one station per pollutant and all timestamps are recent, so the data give a current but very narrow picture of air quality in the municipality. Users should keep in mind that conditions can differ across neighborhoods and throughout the day, and that additional measurements would be needed to capture such spatial or temporal changes.

Data notes
The data shown for Casirate d'Adda are based on four valid measurements and have been refreshed within the past three days, with the latest update recorded at 2026‑02‑08 19:00 UTC.
