Air quality today

The air quality in Ferentino today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 18.0 and a PM10 reference value of 23.0, based on six valid observations collected via OpenAQ.

These figures reflect the current monitoring results for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Ferentino air‑quality dataset contains six measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO2), total nitrogen oxides (NOX), particulate matter 10 µm or smaller (PM10) and particulate matter 2.5 µm or smaller (PM2.5). These values come from three monitoring stations, giving a total of nine data rows across the pollutants.

The most recent measurements are fairly fresh for most species: NO2, NO, NOX, PM10 and PM2.5 were all last updated on 2026‑02‑09 or 2026‑02‑08, i.e., within the past week. CO is an outlier, with its latest reading dated 2023‑01‑09, making it over three years old. Across the dataset, six of the nine rows are from the last seven days, while three rows (all CO) fall into the “old data” category.

Looking at the numbers, NO2 ranges from a low of 6 µg/m³ to a high of 36 µg/m³, with a median of 9 µg/m³ and the 10th‑percentile at about 6.6 µg/m³ and the 90th‑percentile near 30.6 µg/m³, indicating modest variability. CO values span 500 to 1 000 µg/m³, median 750 µg/m³, with a tighter spread between the 10th (550) and 90th (950) percentiles. The other pollutants are single‑value entries: NO at 1 µg/m³, NOX at 11 µg/m³, PM10 at 23 µg/m³ and PM2.5 at 18 µg/m³, each recorded on the same recent date.

Overall, Ferentino’s dataset offers up‑to‑date information for five of the six pollutants but relies on an outdated CO reading. The limited number of stations means spatial coverage is modest, so conditions can differ across neighborhoods and times not captured by these snapshots.

Data notes

The data shown for Ferentino reflects six valid measurements and is updated within three days, with the most recent reading recorded on 2026‑02‑09 at 03:00 UTC. These values provide a current snapshot of ambient air quality across the city, but conditions can differ by neighbourhood and change throughout the day, so local variations may not be captured in this summary.
