Air quality today
The air quality in Cagliari today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).
Measurements from four valid sampling points show a PM2.5 concentration of 12.21 µg/m³, while no reference value is available for PM10. Data is shown via OpenAQ. 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 dataset for Cagliari includes five measured pollutants—carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), fine particulate matter (PM2.5) and sulfur dioxide (SO2). All values come from a single monitoring station, identified as CENCA1, so the city‑wide picture is based on one location rather than a network of sites.
Each pollutant shows a single recorded value because there is only one row of data. CO is reported at 244.5 µg/m³ (lastupdated: 2026-02-07 04:00 UTC), NO2 at 19.0249 µg/m³ (lastupdated: 2026-02-07 04:00 UTC), O3 at 53.728 µg/m³ (lastupdated: 2026-02-07 03:00 UTC), PM2.5 at 12.21 µg/m³ (lastupdated: 2026-02-07 04:00 UTC) and SO2 at 0.9991 µg/m³ (last_updated: 2026-02-07 04:00 UTC). For every pollutant the minimum, median and maximum are identical, indicating no observed spread in the data for the reporting period.
The timestamps are all within the last seven days, which means the information is relatively fresh. However, because only one station contributes, the dataset does not capture spatial variability across different neighborhoods or micro‑environments in Cagliari. Consequently, while the numbers give a snapshot of current concentrations at CENCA1, they cannot represent city‑wide fluctuations that might occur elsewhere or at other times.

Data notes
The current dataset for Cagliari includes four valid measurements and is updated within 7 days, with the latest refresh recorded on 2026‑02‑07T04:00:00+00:00. These values represent a snapshot of ambient conditions at specific monitoring points; air quality can differ across neighborhoods and change throughout the day, so local conditions may vary from what is shown here.
