Air quality today

Today the air quality in Traun is classified as Moderate. The primary pollutant measured is PM2.5. Recent observations show a PM2.5 concentration of 18.37 µg/m³ and a PM10 concentration of 23.99 µg/m³. These figures are based on four valid measurements and are reported in micrograms per cubic meter. Data is shown via OpenAQ. The measurement set includes both fine and coarse particulate matter, providing a broader view of airborne particles.

The moderate classification places the current conditions between the lowest and highest categories used in the assessment. The reported values reflect the latest available data for the city. No additional pollutants were identified as dominant in the current dataset. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The data set for Traun pulls from 11 individual rows collected at two monitoring sites. All six common pollutants—nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm (PM₁₀), particulate matter 2.5 µm (PM₂.₅) and sulphur dioxide (SO₂)—are represented. Four of the rows have been refreshed within the last three days, while the remaining seven are older; the most recent timestamps are 2026‑02‑10 20:00 UTC for NO₂, O₃, PM₁₀ and PM₂.₅, 2024‑03‑11 12:00 UTC for NO, and 2017‑07‑20 19:00 UTC for SO₂.

Across the recent measurements the observed ranges are modest but show distinct spreads. NO varies from 0.535 µg/m³ up to 8.12 µg/m³ with a median of about 4.33 µg/m³, indicating a relatively wide dispersion for a gas that otherwise sits at low concentrations. NO₂ values sit between 13.39 and 22.61 µg/m³, median 18.0 µg/m³, while O₃ ranges from 20.82 to 30.49 µg/m³, median 25.65 µg/m³. PM₁₀ spans 13.65‑23.99 µg/m³ (median ≈ 18.82) and PM₂.₅ covers 10.10‑18.37 µg/m³ (median ≈ 14.24). In contrast, SO₂ is recorded as a single constant value of 0.67 µg/m³ from the NET.04 station, reflecting very limited spatial coverage for that pollutant.

Because the dataset combines recent and considerably older entries, the picture of current air quality in Traun is uneven. Fresh data are available for most pollutants at the Tischlerstraße site, but NO and especially SO₂ rely on older observations or a different monitoring point, so conditions can differ across locations and times within the city.
