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 Honfleur air‑quality record currently draws from a single monitoring site, so the dataset contains three pollutant rows in total. The available measurements are ozone (O3), particulate matter up to 10 µm (PM10) and sulfur dioxide (SO2). Each row reports one value that also serves as the minimum, median and maximum for its series, indicating that only a single recent observation is on file for each pollutant.
The freshest data point in the set is from 2026‑02‑10 15:00 UTC for both O3 (62.9 µg/m³) and SO2 (0.2 µg/m³), while the PM10 reading dates back to 2026‑02‑09 03:00 UTC. Because every pollutant has just one recorded figure, there is no spread of values to describe variability; the reported median equals the sole measurement. This means the dataset cannot illustrate daily or weekly fluctuations for Honfleur, and any interpretation should keep in mind that conditions may differ across neighbourhoods and times not captured by these timestamps.
Overall, the coverage is limited to one station and three recent rows, all updated within the past week. The data are therefore current but sparse, offering a snapshot rather than a comprehensive view of air quality trends in Honfleur.
