Air quality today

The air quality today in Tulln an der Donau is classified as Moderate. The primary pollutant measured is PM2.5. Current observations record a PM2.5 concentration of 23.45 µg/m³ and a PM10 concentration of 27.5 µg/m³. These concentrations are expressed in micrograms per cubic meter and are based on five valid measurements.

The figures are presented through OpenAQ, which aggregates data from monitoring stations in the area. No additional interpretation is provided beyond the reported values. The dataset reflects conditions at the time of collection and does not include future projections. All reported numbers are rounded to two decimal places for clarity. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The OpenAQ feed for Tulln an der Donau supplies data on ten measured variables – nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter 1 µm (PM1), particulate matter 10 µm (PM10), particulate matter 2.5 µm (PM2.5), relative humidity, sulphur dioxide (SO2), temperature and the sensor‑specific field UM003. For this city the dataset contains fifteen rows drawn from two monitoring stations. Freshness is mixed: five rows were updated within the last three days, another five within the last thirty days, and five are older than thirty days. The most recent timestamps are from 2026‑02‑10 20:00 UTC for PM2.5, NO2, O3, PM10 and SO2, while the NO measurement dates back to 2024‑03‑11 12:00 UTC, and the single PM1 and relative‑humidity values were recorded on 2026‑01‑19 08:00 UTC. No temperature or UM003 values are present in the current feed.

Across the pollutants that have multiple entries, the observed ranges are modest but show variability. PM2.5 values span from 23.45 µg/m³ up to 50.98 µg/m³, with a median of 37.22 µg/m³ and the 10th and 90th percentiles at 26.20 µg/m³ and 48.23 µg/m³ respectively. NO2 ranges between 9.66 µg/m³ and 22 µg/m³, median 15.83 µg/m³; O3 is tightly clustered between 27.44 µg/m³ and 29 µg/m³, median 28.22 µg/m³. PM10 varies from 10 µg/m³ to 27.5 µg/m³, median 18.75 µg/m³, and SO2 from 1.75 µg/m³ to 3 µg/m³, median 2.38 µg/m³. By contrast, NO, PM1 and relative humidity each appear only once (NO = 1.6836524 µg/m³, PM1 = 30.944333362579343 µg/m³, humidity = 53.75 %). This uneven coverage means that while some pollutants have a recent, multi‑row picture of air quality, others are represented by a single, possibly outdated point, and city conditions can differ by location and time.
