Air quality today

The air quality in Klöch today is classified as Good. The primary pollutant measured is PM10.

Eight valid measurements were recorded, with a PM10 reference value of 28.445. No PM2.5 reference value is available for today. The Good classification reflects the combined results of these observations. PM10 represents the concentration of coarser particulate matter in the air. The eight observations provide a basis for the assessment across Klöch in Styria, Austria. The reference value of 28.445 µg/m³ serves as the benchmark for evaluating PM10 levels. All measurements were taken within the same reporting period. Data is shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Klöch air‑quality feed contains measurements for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm (PM₁₀) and sulphur dioxide (SO₂). The data set comprises 20 individual rows collected from three monitoring stations in the Klöch area. Eight of those rows have been updated within the last three days, while the remaining twelve are classified as older records. The most recent timestamps are 2026‑02‑10 20:00 UTC for NO₂, O₃, PM₁₀ and SO₂, and 2024‑03‑11 12:00 UTC for NO, indicating that the nitrogen monoxide values are noticeably less current than the other parameters.

Across the five pollutants the observed concentrations span modest to broader ranges. NO values sit between 0.505 µg/m³ and 1.378 µg/m³, with a median of 0.639 µg/m³ and a 10‑percentile of 0.531 µg/m³, showing a relatively tight distribution. NO₂ ranges from 7.315 µg/m³ up to 12.803 µg/m³, median 11.216 µg/m³, and its 90‑percentile reaches 12.453 µg/m³, indicating most recent readings cluster toward the higher end of the spread. O₃ displays the widest variation, from 23.192 µg/m³ to a peak of 70.0 µg/m³, median 43.877 µg/m³, with the 10‑percentile at 23.464 µg/m³ and the 90‑percentile at 68.096 µg/m³. PM₁₀ measurements fall between 8.985 µg/m³ and 33.040 µg/m³, median 29.025 µg/m³, while SO₂ spans 1.0 µg/m³ to 2.337 µg/m³, median 1.708 µg/m³.

Because the dataset relies on only three stations and includes a mix of recent and older rows, the snapshot reflects conditions that can differ across locations and times within Klöch. The concentration ranges and median values give a picture of typical levels, but the limited and partly dated coverage means that short‑term fluctuations may not be fully captured.
