Air quality today
The air quality in Bourg‑en‑Bresse today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 2.4 µg/m³ and a PM10 reference value of 4.5 µg/m³, based on four valid observations collected via OpenAQ.
These figures indicate that the current concentrations are within the range associated with the Good category. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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 Bourg‑en‑Bresse includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). All data come from a single monitoring station, so the dataset contains five rows in total.
The most recent observations were taken on 2026‑02‑10 at 15:00 UTC for NO₂, O₃, PM₁₀ and PM₂.5, while the NO value dates back to 2024‑03‑11 at 09:00 UTC. This means that four of the five pollutants have been updated within the last three days, but the nitrogen monoxide reading is older by almost two years. Each pollutant shows a single reported concentration with no variation across the recorded period: NO 0.4 µg/m³, NO₂ 5.7 µg/m³, O₃ 66.3 µg/m³, PM₁₀ 4.5 µg/m³ and PM₂.₅ 2.4 µg/m³. The minimum, median and maximum values are identical for every pollutant, indicating that the dataset captures only one snapshot rather than a range of measurements.
Because the coverage relies on just one station, spatial differences across Bourg‑en‑Bresse are not reflected in these numbers, and the older NO reading highlights a gap in recent data for that specific gas. Overall, the dataset provides a very recent picture for most pollutants but offers limited depth or temporal spread, so conditions can still vary by location and time beyond what is shown here.
