The air quality in Bois‑Herpin is classified as Good today. The primary pollutant identified is PM2.5 (fine particles).

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 air‑quality record for Bois‑Herpin currently draws from a single monitoring location, giving a snapshot rather than a citywide network. All three measured pollutants – ozone (O₃), particulate matter 10 µm or less (PM10) and fine particulate matter 2.5 µm or less (PM2.5) – are reported from this one station, and the most recent readings were logged on 2026‑02‑10 at 15:00 UTC, which falls within the “updated within three days” freshness category.
For ozone the dataset shows a single value of 74.0 µg/m³, which is both the minimum, median and maximum observed for the period covered; there is no spread in the data because only one measurement exists. Particulate matter follows the same pattern: PM10 registers at 4.5 µg/m³ and PM2.5 at 3.0 µg/m³, each representing the sole observation recorded. Because the station provides just one row of data for each pollutant, statistical summaries such as inter‑percentile ranges (p10, p90) are identical to the single value reported.
The limited coverage means that while the figures are recent and technically up‑to‑date, they capture conditions at only one rural southern zone within Bois‑Herpin. Consequently, variations across different neighborhoods or times of day are not reflected in this dataset. Users should keep in mind that the current snapshot offers a precise but narrow view of air quality, and broader spatial or temporal patterns would require additional monitoring sites or more frequent sampling.
