Air quality today

The air quality in Atzenbrugg today is classified as Moderate. The primary pollutant identified is PM2.5. Current observations report PM2.5 at 21.5 µg/m³ and PM10 at 25.0 µg/m³. The reference values for these fractions are 21.5 µg/m³ for PM2.5 and 25.0 µg/m³ for PM10. These figures are derived from five valid measurements taken across the city. Data is shown via OpenAQ. These measurements are part of the OpenAQ network and correspond to the reference thresholds used in the assessment.

The five samples were collected during the reporting period and represent the latest available data for Atzenbrugg. The reported numbers reflect the conditions at the time the samples were taken. No other pollutant is highlighted as dominant in this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Atzenbrugg air‑quality feed contains measurements for 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). The dataset is built from nine individual rows collected at two monitoring stations, so each station contributes several observations for some pollutants while others are represented by a single row.

Across the nine rows, five entries have been refreshed within the last three days, while four rows are classified as old. The most recent timestamps are from 2026‑02‑10 20:00 UTC for NO2, PM10, SO2, O3 and PM2.5, indicating that the majority of the data is very current. The NO measurement, however, dates back to 2024‑03‑11 12:00 UTC and is the only older record in the set.

For the pollutants with multiple recent rows, the observed values show a modest spread. NO2 ranges from 9.08 µg/m³ to 9.85 µg/m³ with a median of 9.47 µg/m³, while PM10 varies between 14 µg/m³ and 25 µg/m³, median 19.5 µg/m³. SO2 values lie between 0.90 µg/m³ and 2.05 µg/m³, median 1.48 µg/m³. In contrast, O3, PM2.5 and NO each have a single reported value—28.04 µg/m³, 21.5 µg/m³ and 2.24 µg/m³ respectively—so no internal range can be derived for those compounds.

These figures illustrate that the dataset provides recent, multi‑point coverage for NO2, PM10 and SO2, but only single‑point snapshots for NO, O3 and PM2.5. Because the city is monitored by just two stations, conditions can differ across neighborhoods and times, especially for the pollutants with limited observations.
