Air quality today
The air quality in the Municipal Unit of Ano Liosia is classified as Good today. The primary pollutant identified is PM10, which represents coarser particulate matter measured in the area.
Three valid measurements were recorded, and the reference value for PM10 is 39.0 micrograms per cubic metre. No data are available for PM2.5 at this time. 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 air‑quality record for the Municipal Unit of Ano Liosia currently draws from three sensor rows, each providing a single measurement that was last refreshed on 2026‑02‑07 at 02:00 UTC. All three pollutants tracked by OpenAQ – nitrogen dioxide (NO₂), ozone (O₃) and particulate matter up to 10 µm (PM₁₀) – are represented, so the dataset covers the full set of standard urban indicators.
For NO₂ the only reported value is 14.0 µg/m³, which also serves as the minimum, median and maximum across the available row. Ozone shows a uniform reading of 27.0 µg/m³, again identical for its min‑med‑max spread. PM₁₀ is recorded at 39.0 µg/m³ with no variation among the three statistical points. Because each pollutant has exactly one observation, there is no internal range to describe; the data set therefore reflects a single snapshot rather than a distribution over time.
All three rows fall into the “updated within seven days” freshness bucket, meaning the most recent measurements are less than a week old. No older or unknown‑timestamp entries exist in this collection, so the current picture is as fresh as the source provides, but it also means that temporal trends cannot be inferred from this snapshot alone. With only one location contributing data for each pollutant, spatial coverage across Ano Liosia is limited; conditions may differ in other neighborhoods or at different times of day. Users should keep in mind that these figures represent a brief moment captured by a small number of sensors rather than a comprehensive, continuously updated monitoring network.

Data notes
The dataset for Ano Liosia includes three valid measurements and is marked as Updated within 7 days, with the most recent reading recorded on 2026‑02‑07T02:00:00+00:00. These figures represent a snapshot of conditions at specific monitoring points; air quality can differ across neighborhoods and change throughout the day, so values may not reflect the experience at every location or time within the city.
