Air quality today

The air quality in Kozani is currently classified as Moderate. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 11.0 and a PM10 reference value of 12.0, based on five valid observations collected via OpenAQ.

These figures reflect the present conditions without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality record for Kozani draws on a single monitoring station that supplies six separate pollutant rows, one each for carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All six measurements were last refreshed on 2026‑02‑10 at 20:00 UTC, which falls within the three‑day freshness window used by the OpenAQ platform.

Each pollutant currently shows a single reported value, so the statistical spread is essentially zero. CO registers at 300 µg/m³, NO₂ at 7 µg/m³, O₃ at 42 µg/m³, PM₁₀ at 12 µg/m³, PM₂.₅ at 11 µg/m³ and SO₂ at 2 µg/m³; the minimum, median and maximum for every parameter are identical to these figures. Because there is only one station contributing data, the dataset does not capture spatial variation across Kozani, and any changes that occur outside the immediate vicinity of the sensor will not be reflected here.

Overall the dataset is very recent but limited in breadth: six pollutant rows from a single site provide a snapshot rather than a comprehensive picture of city‑wide air quality. Users should keep in mind that conditions can differ by neighbourhood and time of day, and that additional monitoring locations would be needed to describe those variations more fully.

Data notes

The dataset for Kozani includes five valid measurements and is updated within 3 days, with the most recent values recorded on 2026‑02‑10 at 20:00 UTC. These figures represent a snapshot of ambient conditions captured by the monitoring network; actual air quality can differ across neighborhoods and change throughout the day. Users should consider local variations when interpreting the information presented here.
