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 La Coulonche air‑quality record is built from a single monitoring site, the MERA station, which supplies three pollutant measurements: ozone (O₃), particulate matter up to 10 µm (PM10) and fine particles up to 2.5 µm (PM2.5). All three variables are reported in micrograms per cubic metre and each has exactly one data row, so the dataset contains three rows in total.
The most recent observation for every pollutant was recorded on 2026‑02‑10 at 15:00 UTC, meaning the information is fresh within the last three days. Because there is only one reading per pollutant, the statistical spread is zero; the minimum, median, and maximum values are identical. Ozone registers a concentration of 61.5 µg/m³, PM10 shows 0.5 µg/m³ and PM2.5 records 0.4 µg/m³ at the MERA location. With no variation across time or between multiple stations, these figures represent the current snapshot rather than a range of conditions across La Coulonche.
Given the single‑station coverage, the dataset cannot capture spatial differences that may exist within the town, and any changes that occur after the last update will not be reflected until a new measurement is uploaded. The uniformity of the data—identical min, median and max values for each pollutant—highlights the limited depth of the record at present, while the recent timestamp assures that what is shown is up‑to‑date as of early February 2026.

Data notes
The data shown for La Coulonche reflects three valid measurements and is updated within 3 days, with the latest reading recorded on 2026‑02‑10 at 15:00 UTC. This snapshot provides a current view of ambient air quality but conditions can differ across neighbourhoods and change throughout the day, so local variations may not be captured in these figures.
