Air quality today

The air quality today in Klagenfurt, the capital of Carinthia in Austria, is classified as Moderate. The primary pollutant identified is PM2.5. Current measurements show PM2.5 at 19.385 µg/m³ and PM10 at 28.05 µg/m³. These concentrations are based on ten valid observations and represent the latest available data for the city.

Data is shown via OpenAQ, which aggregates readings from local monitoring stations. The reported PM2.5 level of 19.385 µg/m³ is close to the reference value used for this category, while the PM10 level of 28.05 µg/m³ matches its reference point. Ten measurements were incorporated into the 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 Klagenfurt in Carinthia contains measurements for carbon monoxide, nitrogen monoxide, nitrogen dioxide, ozone, particulate matter ≤ 10 µm, particulate matter ≤ 2.5 µm and sulphur dioxide. Six monitoring sites contribute a total of sixteen recent rows, of which eleven rows have been updated within the last three days and five rows are older than three days. The newest timestamps cluster on 2026‑02‑10 20:00 UTC for most pollutants, while the nitrogen monoxide reading dates back to 2024‑03‑11 12:00 UTC, indicating that not all substances are refreshed at the same pace.

Across the dataset the depth of coverage varies markedly. Nitrogen dioxide is the most represented pollutant with six rows from five stations; its values span from a negative minimum of –1.0 µg/m³ to a maximum of 37.93 µg/m³, with a median of about 20.34 µg/m³ and a 90th‑percentile near 37.5 µg/m³. Ozone appears in three rows from two stations, ranging from 2.185 to 35.215 µg/m³ and centering around a median of 5 µg/m³. In contrast, particulate matter measurements are tightly clustered: PM10 values sit between 26.95 and 28.05 µg/m³ with a median of 27.5 µg/m³, while PM2.5 ranges from 14.5 to 19.385 µg/m³ and has a median of roughly 16.94 µg/m³. Carbon monoxide, sulphur dioxide and nitrogen monoxide each have a single recent entry – 625.05 µg/m³ for CO at Völkermarkter Straße, 0.23 µg/m³ for SO₂ and 4.51 µg/m³ for NO at Sterneckstraße – reflecting limited spatial sampling for these gases.

These figures show that while the city’s air‑quality monitoring provides fresh data for several key pollutants, the number of observations is uneven, with some gases captured at multiple sites and others represented by a single, possibly dated, measurement. Consequently, the snapshot may not capture the full spatial variability of all pollutants across Klagenfurt at any given moment.
