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 Payerne in the canton of Vaud contains measurements for six key pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂, written as NO2), ozone (O₃, written as O3), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM2.5, written as PM25) and sulfur dioxide (SO₂). All six pollutants are represented by a single monitoring row each, giving a total of six rows from one station that supplies the data.
Each pollutant’s most recent value was recorded on 2026‑02‑10, with five of them logged at 20:00 UTC and SO₂ at 13:00 UTC. The OpenAQ feed flags these entries as “Updated within 7 days,” indicating that the latest observations are fresh and fall well inside the one‑week freshness window. Because every pollutant has exactly one reported value, the minimum, median and maximum for each are identical: CO is 172.6 µg/m³, NO₂ is 7.4576 µg/m³, O₃ is 63.9546 µg/m³, PM10 is 2.5158 µg/m³, PM2.5 is 1.8471 µg/m³ and SO₂ is 0.0191 µg/m³.
The uniformity of the data means there is no spread to describe – each pollutant shows a single point measurement rather than a range over time. While this provides an up‑to‑date snapshot for Payerne, it also highlights limited temporal coverage; any variation that occurs outside the recorded moment will not be captured in the current dataset. Consequently, while the numbers give a clear picture of the pollutants present at the time of sampling, they do not reflect fluctuations that might arise later in the day or across different locations within the city.

Data notes
The data shown for Payerne reflects six valid measurements and is updated within 3 days, with the latest values recorded on 2026‑02‑10 at 20:00 UTC.
