Air quality today
The air quality today in Wals‑Siezenheim is classified as Moderate. The main pollutant measured is PM2.5. The reported PM2.5 concentration is 14.8 µg/m³. PM10 is recorded at 21.1365 µg/m³. Data are shown via OpenAQ. The classification is based on the measured concentrations of the listed pollutants.
Three valid measurement points provide the current values, and the measurement count of three indicates the number of observations used to derive these figures. These observations are part of the routine monitoring effort for the region and represent the most recent data available for the city. All values are expressed in micrograms per cubic meter. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Wals‑Siezenheim currently provides three measured pollutants – nitrogen dioxide (NO2), particulate matter up to 10 µm (PM10) and particulate matter up to 2.5 µm (PM2.5) – all expressed in micrograms per cubic metre. These readings come from a single OpenAQ‑registered monitoring site located on the Salzburg Stadtautobahn A1. In total the city’s record contains three rows of data, one for each pollutant, and every row was last updated on 2026‑02‑10 20:00 UTC, which places all entries in the “updated within three days” freshness category. No older or unknown‑timestamp records are present, indicating that the available information reflects the most recent conditions captured at that location.
Across the three pollutants the reported values are identical to their minimum, median and maximum figures, meaning there is no observed spread in the data set. NO2 registers at 25.8579845 µg/m³, PM10 at 21.1365 µg/m³ and PM2.5 at 14.8 µg/m³, each representing the central tendency for its respective series. Because each pollutant is measured at the same site, the dataset offers a consistent snapshot of air quality at that specific point, but it does not capture spatial variation across the wider municipal area. Consequently, while the numbers are current and uniformly reported, they represent a limited geographic slice; conditions elsewhere in Wals‑Siezenheim may differ from those recorded on the highway monitoring station.
