Air quality today
The air quality in Ronchi dei Legionari is classified as Good today. The primary pollutant identified is PM10, and the measured concentration aligns with a reference value of 11.36 µg/m³ based on three valid observations.
Data are shown via OpenAQ and reflect the current assessment for this location. 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 dataset for Ronchi dei Legionari currently contains five individual pollutant measurements – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10) and sulphur dioxide (SO₂). Each pollutant is represented by a single row, so the station coverage consists of five rows in total. All values are expressed in micrograms per cubic metre (µg/m³).
The timestamps show mixed freshness. The NO reading dates back to 2024‑03‑11 10:00 UTC and the O₃ value is from 2025‑12‑31 09:00 UTC, both clearly older than a year. In contrast, the NO₂, PM10 and SO₂ measurements were all updated on 2026‑02‑07 20:00 UTC, which falls within the last seven days. Because only one observation per pollutant is available, each metric has identical minimum, median and maximum values – for example, NO is consistently reported as 6.14 µg/m³, NO₂ as 14.19 µg/m³, O₃ as 46.88 µg/m³, PM10 as 11.36 µg/m³ and SO₂ as 3.38 µg/m³.
These facts lead to a few concrete observations. First, the data set is very small; with only five rows there is limited spatial or temporal depth for Ronchi dei Legionari. Second, the recency of the information varies markedly across pollutants, meaning that recent conditions are captured for NO₂, PM10 and SO₂ but not for NO or O₃. Third, because each pollutant has a single recorded value, there is no observable spread or trend within this snapshot – the reported figures represent both the minimum and maximum observed concentrations at the sampled location (Vermegliano – via Mostegane). Consequently, while the dataset provides a basic picture of current air quality components, it does not reflect variability that may occur across different parts of the city or over time.

Data notes
The current dataset for Ronchi dei Legionari includes three valid measurements and is marked as Updated within 7 days, with the latest values recorded on 2026‑02‑07T20:00:00+00:00. These figures represent a snapshot of ambient conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so local variations may not be reflected in this summary.
