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 Opfikon air‑quality dataset currently contains measurements for three pollutants – nitrogen dioxide (NO2), ozone (O3) and particulate matter 10 µm or less (PM10). All values come from a single monitoring site, Opfikon‑Balsberg, so the city’s coverage is limited to one location but includes all three substances. The most recent reading for each pollutant was recorded on 2026‑02‑10 at 20:00 UTC and the data are marked as having been updated within the past seven days, indicating that the information is relatively fresh.
For NO2 the concentration is reported as a single value of 36.468 µg/m³; both the minimum, median and maximum are identical, showing no observed variation in the available record. Ozone registers at 0.9207 µg/m³ with the same uniform statistics, while PM10 measures 22.6569 µg/m³, again without any spread between its reported percentiles. Because each pollutant has only one recorded figure, there is no range or distribution to describe beyond these point values.
Overall, the dataset provides a snapshot rather than a time series: three rows of data (one per pollutant) from one station, all captured at the same moment and updated recently. While this offers an up‑to‑date picture of conditions at Opfikon‑Balsberg, it does not reflect spatial or temporal variability across the wider city area. Users should keep in mind that air quality can differ by location and over time, and the current data set captures only a single point in both dimensions.
