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 Zell am See contains measurements of five key air‑quality pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter up to 10 µm (PM₁₀) and particulate matter up to 2.5 µm (PM₂.₅). All values come from a single monitoring site, the Zell am See Freizeitzentrum/Eishalle, giving a total of five data rows – one for each pollutant.
The most recent timestamps in the collection are from 2026‑02‑10 20:00 UTC for NO₂, O₃, PM₁₀ and PM₂.5, all marked as “updated within 3 days”. The NO measurement is older, last recorded on 2024‑03‑11 12:00 UTC and labelled “old data”. Because the dataset relies on a single station, spatial coverage across the city is limited; conditions can differ in other neighbourhoods or at different times of day.
Across the five pollutants the reported values show no internal variation – each metric has identical minimum, median and maximum figures. NO sits at 3.42966222 µg/m³, NO₂ at 36.02085 µg/m³, O₃ at 32.606 µg/m³, PM₁₀ at 37.68 µg/m³ and PM₂.5 at 11.1625 µg/m³. This uniformity reflects the snapshot nature of the data rather than a range of observed conditions. Consequently, while the recent updates for most pollutants suggest timely reporting, the single‑site coverage and the older NO record mean that the dataset provides only a limited picture of Zell am See’s overall air quality at any given moment.

Data notes
The data shown are based on four valid measurements and were refreshed recently, with the latest update recorded on 2026‑02‑10 at 20:00 UTC (Updated within 3 days). This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in Zell am See.
