Air quality today

The air quality in Arnoldstein, Carinthia, is currently classified as Good. The primary pollutant identified is PM10, with a measured concentration of approximately 5.9 µg/m³ based on three valid observations. This PM10 figure matches the reference value of 5.9 µg/m³ applied in the assessment. No PM2.5 value is reported for the same time frame.

All figures are provided through the OpenAQ platform, which compiles data from local monitoring stations. The three measurements reflect the most recent sampling period available. The dataset includes three distinct sensor readings that were aggregated for the current rating. OpenAQ updates its database as new data become available, but the figures shown here reflect the latest complete set. The numbers are presented without additional interpretation. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Arnoldstein air‑quality record draws from three monitoring sites that together contribute nine data rows. For this city three key pollutants are reported: ozone (O3), particulate matter up to 10 µm (PM10) and sulfur dioxide (SO2). The most recent measurements for each pollutant were logged on 2026‑02‑10 at 20:00 UTC, so the freshest values are less than three days old. However, six of the nine rows are classified as “old”, meaning a substantial portion of the historical record predates the three‑day window.

Ozone values span from a low of 22.2 µg/m³ to a high of 50.7 µg/m³, with a median of 34.215 µg/m³ and the central 80 % of observations falling between roughly 24.6 and 47.4 µg/m³. PM10 concentrations range between 3.0 and 39.57 µg/m³, centering on a median of 5.905 µg/m³; the 10th and 90th percentiles are about 3.58 and 32.84 µg/m³ respectively, indicating that most recent readings are low but occasional spikes reach near 40 µg/m³. Sulfur dioxide shows a narrower spread, from 0.28 up to 4.765 µg/m³, with a median of 4.56 µg/m³ and the 10th–90th percentile band from roughly 1.14 to 4.72 µg/m³.

The dataset therefore offers a complete set of three pollutants but the coverage is uneven in time: only a third of the rows are recent, while the majority are older entries. This mix means that while the latest snapshot provides a clear picture of current concentrations at the three stations, longer‑term trends for Arnoldstein may be less certain because many observations are dated. Users should keep in mind that air‑quality conditions can differ across neighborhoods and over short periods, and the available data reflects the specific locations and timestamps captured by the OpenAQ network.
