What the data includes

Acquapendente’s OpenAQ feed currently provides data for six pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃), particulate matter 10 µm or less (PM10) and particulate matter 2.5 µm or less (PM2.5). The dataset comprises eight individual rows drawn from two monitoring stations, meaning each station contributes a small set of observations rather than continuous streams.

All six pollutants have recent updates that fall within the last seven days, with the newest timestamps recorded on 2026‑02‑09 at 03:00 UTC for NO₂ and O₃, and on 2026‑02‑09 at 00:00 UTC for NO, NOX, PM10 and PM2.5. This indicates that the most current measurements are no older than two days from today’s date, offering a fairly fresh snapshot of air quality in the town.

The values themselves show very limited variability. For NO₂ the minimum, median and maximum are all 2 µg/m³, while O₃ ranges narrowly between 44 and 47 µg/m³ with a median of 45.5 µg/m³. NO registers a constant 0 µg/m³ across its single reading, and NOX is fixed at 3 µg/m³. Particulate matter also displays uniform figures: PM10 stays at 6 µg/m³ and PM2.5 at 5 µg/m³ for the available rows. Because each pollutant has only one or two recent records, there is little spread to describe typical fluctuations; the dataset essentially captures a single point in time rather than a broader distribution.

Overall, Acquapendente’s air‑quality reporting covers all major regulated pollutants but does so with a modest number of stations and a very small set of recent observations. While the timestamps are up‑to‑date, the limited row count means that conditions can differ across neighborhoods or over short periods without being reflected in this snapshot. Users should keep in mind that the data represent a narrow temporal window rather than continuous monitoring.

Data notes

The data shown for Acquapendente reflects eight valid measurements and is marked as Updated within 3 days, with the latest values recorded on 2026‑02‑09 at 03:00 UTC. This snapshot provides a recent overview of ambient air quality but remember that conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
