Air quality today

The air quality in Ancona today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 value of 4.9 µg/m³ and a PM10 value of 11.1 µg/m³, based on five valid observations collected via OpenAQ.

Overall conditions meet the criteria for a Good rating according to the available data. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Ancona includes seven measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 1 (PM₁), particulate matter 10 (PM₁₀), fine particulate matter 2.5 (PM₂.₅) and sulfur dioxide (SO₂). All values come from a single monitoring location, the Ancona Cittadella station, so the city‑wide picture is based on one row per pollutant. The most recent updates for CO, NO₂, O₃, PM₁₀, PM₂.₅ and SO₂ were recorded on 2026-02-07 20:00 UTC, which places them in the “updated within 7 days” freshness bucket. The only older entry is PM₁, last refreshed on 2024-03-11 10:00 UTC, flagged as old data.

Because each pollutant has a single recorded value, the statistical spread is essentially zero – the minimum, median and maximum are identical for every metric. CO registers at 700.0 µg/m³, NO₂ at 25.2 µg/m³, O₃ at 39.0 µg/m³, PM₁ at 8.4 µg/m³, PM₁₀ at 11.1 µg/m³, PM₂.5 at 4.9 µg/m³ and SO₂ also at 8.4 µg/m³. The percentile values (10th and 90th) match these figures as well, confirming the lack of variation in this snapshot.

The coverage is therefore narrow: only one monitoring site contributes data for all seven pollutants, and while most readings are recent, the PM₁ measurement is more than a year old. This limited spatial and temporal breadth means that conditions can differ across neighborhoods or change throughout the day, and the dataset may not capture those variations fully.
