What the data includes

Civitavecchia’s OpenAQ feed contains eight measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulfur dioxide (SO₂). The data come from 14 monitoring stations that together have contributed 67 individual rows of observation. Of those rows, 56 were recorded within the last seven days, while 11 are older than a week; no entries are marked as unknown or pending.

The freshest timestamps vary by pollutant but all fall between 2026‑02‑08 and 2026‑02‑09. For example, CO was last reported at Civitavecchia‑ via Roma on 2026‑02‑09 03:00 UTC with a value of 300.0 µg/m³, while the most recent NO₂ reading comes from S.Gordiano on 2026‑02‑09 03:00 UTC at 2.0 µg/m³. Ozone shows the highest single measurement among the set, recorded at S.Agostino on 2026‑02‑09 03:00 UTC at 71.0 µg/m³; its median value is 47.0 µg/m³ with a spread from 11.0 to 70.6 µg/m³ (10th–90th percentile). Particulate matter concentrations are modest, with PM10 medians of 12.0 µg/m³ (range 7.0‑24.0) and PM2.5 medians of 4.0 µg/m³ (range 3.0‑12.0). NO and NOX each have only a handful of recent rows (11), showing median values of 1.0 µg/m³ and 3.0 µg/m³ respectively, while SO₂ is represented by seven recent entries with a median of 1.5 µg/m³.

Overall the dataset provides fairly current coverage for most pollutants, but the number of rows differs markedly: ozone, CO and NO₂ each have five or more fresh observations, whereas NO, NOX and SO₂ are based on fewer than a dozen recent points. This uneven distribution means that while the city’s air‑quality picture is up‑to‑date in many locations, some pollutants are captured at only a limited number of stations, so conditions can still vary across neighborhoods and over short time spans.
