Air quality today

The air quality today in Cassino is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).

Measurements show a PM2.5 reference value of 15.0 µg/m³ and a PM10 reference value of 22.0 µg/m³, based on six valid observations recorded by OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Cassino air‑quality dataset contains six measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO2), total nitrogen oxides (NOX), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µg (PM2.5) and sulphur dioxide (SO2). All values come from three monitoring stations, giving a total of ten rows of data across the pollutants.

The most recent measurements are very fresh for five of the six substances: NO, NOX, PM10 and PM2.5 were last recorded on 2026‑02‑08, while NO2 was updated on 2026‑02‑09. SO2 is the exception, with its latest entry dating back to 2024‑05‑16, so that particular series is considerably older than the others. Across the dataset, six rows have been refreshed within the past week, four are classified as “old” and none are unknown or missing.

The recorded values show limited variability. For NO2 the minimum observed concentration is 19 µg/m³, the median 35 µg/m³ and the maximum 91 µg/m³, with a 10th‑percentile of about 22 µg/m³ and a 90th‑percentile near 80 µg/m³. In contrast, NO, NOX, PM10 and PM2.5 each have a single reported value – 7 µg/m³ for NO, 46 µg/m³ for NOX, 22 µg/m³ for PM10 and 15 µg/m³ for PM2.5 – so no spread can be derived for those pollutants. SO2 shows an unusual range from –1 µg/m³ to 7 µg/m³, reflecting the older data quality.

Overall the dataset provides a recent snapshot for most pollutants but is uneven: five substances have up‑to‑date readings while SO2 remains dated, and only NO2 offers enough observations to describe a distribution. Consequently, while the current figures give a clear picture of the latest conditions at the three stations, they do not capture broader temporal or spatial variations that may exist across Cassino.
