Air quality today

The air quality in Feldkirch today is classified as Good. The primary pollutant identified is PM10, with a measured concentration of approximately 32.7 µg/m³. Two valid observations contributed to this figure, and no PM2.5 value is reported for today. The reference value applied for PM10 assessment is 32.7 µg/m³, which aligns with the observed level. The overall category is derived from the available measurements.

These data are aggregated and shown via OpenAQ, which collects information from local monitoring stations in Vorarlberg, reflecting the current monitoring conditions without additional interpretation. The presented figures represent a snapshot for the current reporting period. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Feldkirch in Vorarlberg pulls measurements from two monitoring stations and currently contains nine individual rows of data. All three pollutants tracked – carbon monoxide (CO), nitrogen dioxide (NO₂) and particulate matter 10 µm (PM10) – are reported in micrograms per cubic metre. The most recent values for each pollutant were recorded at the Feldkirch Bärenkreuzung site on 2026‑02‑10 20:00 UTC, and the same timestamp appears for CO, NO₂ and PM10, indicating a synchronized update across the three series.

CO readings span a wide interval, from a low of about 576 µg/m³ up to a high of roughly 1 613 µg/m³, with a median near 976 µg/m³ and the 10th‑percentile at 656 µg/m³ and the 90th‑percentile at 1 486 µg/m³. In contrast, NO₂ values are clustered in a narrower band, ranging from 36.6 to 77 µg/m³, a median of 46.8 µg/m³, and percentiles of 38.6 (10th) and 71.0 (90th). PM10 shows the tightest distribution, moving between 32.7 and 46.0 µg/m³, with a median of 41 µg/m³ and percentiles of 34.4 (10th) and 45.0 (90th). These figures illustrate that CO exhibits the greatest variability among the three, while PM10 remains comparatively stable.

Freshness of the data is mixed: three of the nine rows were updated within the last three days, whereas the remaining six are classified as older. Because a majority of the entries are not recent, the snapshot may not capture short‑term fluctuations that can occur across different parts of the city. Users should keep in mind that conditions can differ by location and time, and the available measurements represent the specific moments captured by the two stations.
