Air quality today

The air quality in Lienz, Tyrol, Austria is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). The reported PM2.5 reference value is 27.9045 µg/m³, and the PM10 reference value is 33.6205 µg/m³. These concentrations are expressed in micrograms per cubic meter of air.

The assessment is based on five valid measurements that are aggregated and displayed through OpenAQ. No additional pollutants are highlighted in the current data set. The figures represent the most recent sampling period available from the OpenAQ network. These numbers provide a snapshot of ambient particulate concentrations for the city on the reporting day. All reported values are derived from the same set of five observations. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Lienz air‑quality feed contains six measured pollutants – carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). Data come from two monitoring sites, Amlacherkreuzung and Tiefbrunnen, giving a total of ten rows. Freshness is split evenly: five rows were updated within the last three days, while the remaining five are classified as “old”. The most recent timestamps are 2026‑02‑10 20:00 UTC for NO₂, PM10, PM2.5 and O₃, whereas CO’s latest entry dates to 2021‑12‑30 23:00 UTC and NO’s to 2024‑03‑11 12:00 UTC.

Across the recent data, NO₂ shows a median concentration of 61.18 µg/m³ with values ranging from 48.71 to 108 µg/m³, indicating a moderate spread around the central tendency. PM10’s median is 24.81 µg/m³, varying between 16.0 and 33.62 µg/m³, while PM2.5 is represented by a single recent measurement of 27.90 µg/m³. Ozone is also captured by a single recent value of 5.888 µg/m³. In contrast, CO records consistently high levels around 1,020 µg/m³, with a minimum of 995.0, a median of 1,019.76 and a maximum of 1,044.52 µg/m³, but these figures are based on older data. NO is reported at a low 0.956 µg/m³, again from an older entry.

The dataset therefore provides a fairly current picture for NO₂, PM10, PM2.5 and O₃, but the coverage for CO and NO is dated, which means city‑wide conditions for those gases may not reflect the latest situation. Because only two stations contribute, spatial variation within Lienz can be significant, and the mix of recent and older rows should be kept in mind when interpreting the numbers.
