Air quality today
The air quality in Calusco d'Adda is currently classified as Moderate. The main pollutant identified is PM2.5, with a measured concentration of 21.4 µg/m³. Data from four valid measurements also show a PM10 level of 26.51 µg/m³, reported through OpenAQ.
Overall conditions reflect the moderate category based on these recent readings. 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 Calusco d'Adda air‑quality record contains data for five measured pollutants – nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulphur dioxide (SO₂). All of these come from a single monitoring station, so the dataset consists of one row per pollutant.
The most recent observations are from 8 February 2026 for NO₂, O₃, PM10 and PM2.5, each timestamped at 19:00 UTC, while the SO₂ reading is older, last updated on 11 March 2024 at 10:00 UTC. This means that four of the five pollutants have data that are less than a week old, whereas sulphur dioxide reflects conditions from almost two years ago.
Across the recent measurements the values are identical to their median and extreme points because each pollutant has only one recorded figure. NO₂ registers 15.30 µg/m³, O₃ 49.03 µg/m³, PM10 26.51 µg/m³ and PM2.5 21.40 µg/m³. The spread for these four pollutants is therefore zero – the minimum, median and maximum are all the same. In contrast, the SO₂ figure stands at 5.15 µg/m³, but with no recent updates it cannot be compared directly to the other four.
Because the dataset relies on a single station, spatial coverage across Calusco d'Adda is limited; variations that might exist in different neighbourhoods or at different times of day are not captured here. The freshness of most pollutants suggests a current snapshot for nitrogen dioxide, ozone and particulates, yet the outdated sulphur‑dioxide reading highlights an uneven temporal completeness within the same city profile.

Data notes
The data shown for Calusco d'Adda are based on four valid measurements and have been refreshed within the past three days, with the most recent update recorded at 2026‑02‑08 19:00 UTC. This snapshot reflects conditions measured at specific monitoring points; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
