Air quality today

The air quality in Grünbach, Upper Austria, is currently rated as Good. According to the latest assessment, the dominant pollutant is PM2.5. The reference value for PM2.5 is 2.89 µg/m³, while the reference value for PM10 is 4.63 µg/m³. These figures are derived from five valid measurements collected for the area. The Good category indicates that the measured particulate concentrations are within the reference values used for evaluation.

Data is shown via OpenAQ. The assessment incorporates five valid measurement points, providing a snapshot of particulate levels at the time of sampling, and are presented for public awareness. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Grünbach air‑quality record comes from a single monitoring site in Grünbach bei Freistadt and contains six individual rows of data. Five of those rows were refreshed within the last three days, while one row – the nitrogen monoxide (NO) measurement – dates back to 2024‑03‑11 12:00 UTC. The pollutants for which values are available are nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm (PM10), particulate matter 2.5 µm (PM2.5) and sulphur dioxide (SO₂). All six measurements are expressed in micrograms per cubic metre (µg/m³).

Each pollutant is represented by a single numeric entry, so the reported minimum, median and maximum are identical and the statistical spread for every substance is zero. For example, the NO₂ value is 3.470499 µg/m³, the O₃ value is 78.361 µg/m³, PM10 reads 4.63008 µg/m³, PM2.5 is 2.892234 µg/m³ and SO₂ stands at 2.105499 µg/m³. Because the data set contains only one observation per pollutant, the median equals the listed value and no variability can be derived from the current snapshot.

The timing of the updates is uneven: the five most recent measurements (NO₂, O₃, PM10, PM2.5 and SO₂) were all logged on 2026‑02‑10 20:00 UTC, whereas the NO reading is considerably older. This means that, while most of the data reflects the latest conditions, the NO figure does not capture the current state. With only one station feeding the dataset, the spatial coverage for Grünbach is limited, and conditions can differ across the city and over time.
