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 Neuchâtel currently contains measurements from a single monitoring location, Chaumont. Three pollutants are reported: nitrogen dioxide (NO₂), ozone (O₃) and particulate matter ≤ 10 µm (PM10). For each pollutant the most recent reading was taken on 2026‑02‑10 at 20:00 UTC, which falls within the “updated within 7 days” freshness category.
All three pollutants show identical statistical profiles because only one observation is available. The recorded NO₂ concentration is 2.3967 µg/m³, ozone is 81.1967 µg/m³ and PM10 is 0.2286 µg/m³; each value represents the minimum, median and maximum for its respective series, as well as the 10th and 90th percentiles. This uniformity indicates that there is no observed variability across time or space within the current data set.
Because the coverage consists of just one station, the dataset provides a very limited snapshot of air quality in Neuchâtel. While the timestamps are recent, the lack of multiple locations means conditions elsewhere in the city may differ from those measured at Chaumont. Users should keep in mind that the available figures represent a single point in time and space rather than a comprehensive view of the whole urban area.
