Air quality today

The air quality today in the Municipal Unit of Larissa is assessed as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 11.0 and a PM10 reference value of 19.0, based on eleven valid observations collected via OpenAQ.

These figures reflect the current monitoring snapshot for Larissa on 2026-02-13. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for the Municipal Unit of Larissa contains measurements for six pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). In total there are twelve data rows drawn from three monitoring stations, identified as LARISA‑1, LARISA‑3 and an additional unnamed source that contributes only a single row for each of CO, SO₂ and PM₂.₅. All values were recorded at the same moment: 2026‑02‑10 20:00 UTC, which satisfies the “updated within three days” freshness criterion for every pollutant.

The observed concentrations show a fairly narrow spread for most species. Ozone ranges from 41 to 55 µg/m³ with a median of 52 µg/m³; PM₁₀ varies between 18 and 19 µg/m³, centred on an identical median of 18 µg/m³; NO₂ spans 12‑29 µg/m³ (median 20.5 µg/m³); PM₂.₅ is recorded from 7 to 11 µg/m³ (median 9 µg/m³). Sulphur dioxide and carbon monoxide each have a single reported value – 6 µg/m³ for SO₂ and 400 µg/m³ for CO – reflecting the limited station coverage for these gases. The percentile data (10th‑90th) confirm that most readings cluster tightly around their medians, indicating little variability in the snapshot captured on the reporting date.

Because the dataset relies on only three stations and twelve rows, spatial representation across Larissa is modest. While ozone, PM₁₀, NO₂ and PM₂.₅ benefit from multiple observations, SO₂ and CO are each represented by a single measurement point, which may not capture local differences. All timestamps being recent ensures the information reflects current conditions, but the sparse station network means that air quality can still differ across neighborhoods and times not covered by this snapshot.

Data notes

The dataset for the Municipal Unit of Larissa includes 11 valid measurements and is updated within 3 days, with the most recent data recorded on 2026‑02‑10 at 20:00 UTC. This snapshot reflects conditions at specific monitoring points and times; air quality can differ across neighborhoods and throughout the day, so values shown may not represent every location or moment in the city.
