Air quality today

The overall air quality today is classified as USG. The main pollutant is PM2.5. For Klosterneuburg in Lower Austria, Austria, the reported PM2.5 concentration is 48.2 µg/m³, derived from six valid measurements. PM10 data is not available for this assessment.

These values are reported through OpenAQ. OpenAQ aggregates observations from certified monitoring stations and makes them publicly accessible. The concentration is expressed in micrograms per cubic meter, a standard unit for particulate matter. Six valid measurements provide the basis for the reported average, ensuring that the figure reflects recent ambient conditions. No additional pollutants are highlighted in the current assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The OpenAQ feed for Klosterneuburg in Lower Austria contains twenty rows of measurements drawn from a handful of monitoring sites. Eight of those rows have been updated within the last three days, while the remaining twelve are older, so the overall picture mixes very recent snapshots with data that may no longer reflect current conditions. The dataset includes readings for nitrogen dioxide (NO2), ozone (O3), sulfur dioxide (SO2), nitrogen monoxide (NO), particulate matter of 10 µm (PM10) and 2.5 µm (PM2.5) size, ultrafine particles (PM1), relative humidity, and also lists temperature and UM003 as measured parameters, although no recent values for temperature or UM003 appear in the current rows.

For the pollutants that do have values, the range and typical level can be described numerically. NO2 varies from 9.0 to 27.5 µg/m³ with a median of about 15.3 µg/m³, while ozone spans a broader interval from –1.0 to 58.4 µg/m³ and centers around a median of 44 µg/m³. Sulfur dioxide shows a modest spread, from –1.0 up to 3.0 µg/m³ with a median near 2.1 µg/m³. Particulate matter is unevenly covered: PM10 is reported from two stations, ranging from 14.6 to 19.5 µg/m³ with a median of 17.1 µg/m³; PM2.5 also comes from two sites, ranging from 13.8 to 48.2 µg/m³ and a median of 31.0 µg/m³; PM1 is represented by a single observation of 27.56 µg/m³. Relative humidity is recorded once at 62.79 %. The most recent timestamps are from 2026‑02‑10 20:00 UTC for NO2, O3 and SO2, and from 2026‑02‑10 21:00 UTC for PM2.5, PM1 and humidity, whereas PM10 and NO rely on data from 2025‑12‑19 and 2024‑03‑11 respectively. Because some pollutants are only captured by one or two stations and several rows are dated, the available data give a snapshot rather than a complete, up‑to‑the‑minute view of air quality across the whole city.
