Air quality today
The air quality in Civita Castellana is classified as Good today. The primary pollutant measured is PM10, with a reference value of 17.0 µg/m³ reported from five valid observations.
PM10 levels are within the reference limit, and no other pollutants exceed their thresholds based on the available data. 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 Civita Castellana air‑quality dataset contains five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), particulate matter up to 10 µm (PM₁₀) and sulphur dioxide (SO₂). All of these come from a single monitoring station, so the city’s coverage is limited to one location. The most recent data points are all dated within the past week: NO, NOX and SO₂ were last updated on 2026‑02‑09 at 00:00 UTC, 00:00 UTC and 03:00 UTC respectively; NO₂ was refreshed on 2026‑02‑09 at 03:00 UTC; and PM₁₀ is the oldest entry, recorded on 2026‑02‑08 at 00:00 UTC. Because every pollutant has a timestamp no older than seven days, the information can be considered fairly fresh for this single‑site network.
The numeric values show very little variation across each pollutant. NO registers a constant 0.0 µg/m³, with its minimum, median and maximum all equal to zero. NO₂ is recorded at exactly 3.0 µg/m³, while NOX sits at 9.0 µg/m³; both have identical min‑med‑max figures, indicating no observed spread in the recent period. PM₁₀ measures 17.0 µg/m³ and SO₂ records 2.7 µg/m³, again with uniform statistics (min = median = max). Because each pollutant’s distribution collapses to a single value, there is no discernible range or percentile spread to describe.
With only one monitoring row feeding all five pollutants, the dataset provides a snapshot rather than a city‑wide picture. Conditions can differ across neighborhoods and times of day that are not captured here. Users should keep in mind that while the data are up‑to‑date, they reflect measurements from a single point source and may not represent broader spatial variations within Civita Castellana.

Data notes
The data shown for Civita Castellana is based on five valid measurements and was refreshed within three days, with the latest update recorded at 2026‑02‑09T03:00:00+00:00. This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
