Air quality today
The air quality in Angers today is classified as Good. The primary pollutant measured is PM10, with a reference concentration of 19.6 µg/m³ based on four valid observations recorded by OpenAQ.
These measurements indicate that the current particulate levels 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.

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 Angers air‑quality dataset contains observations for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). The data come from ten measurement rows collected at three monitoring stations across the city, so each pollutant is not necessarily represented at every location.
The most recent values are fairly fresh for some gases but older for others. NO was last recorded on 2024‑03‑11 08:00 UTC, with a maximum of 39.4 µg/m³ reported from the APPENTIS site; NO₂ is up to date as of 2026‑02‑10 05:00 UTC, showing a low of 4.8 µg/m³ at ROI RENE. Ozone data are also recent (2026‑02‑09 03:00 UTC) and uniform, with a single reading of 2.7 µg/m³ from APPENTIS. PM10 measurements were refreshed on 2026‑02‑09 03:00 UTC, ranging from 19.6 to 26.8 µg/m³ at ROI RENE, while the sole PM2.5 entry dates back to 2025‑12‑09 23:00 UTC and records a constant 13.3 µg/m³ at BEAUX ARTS.
Across the pollutants the observed ranges vary considerably. NO spans from 15.4 to 39.4 µg/m³, with a median around 30 µg/m³, indicating notable variability between low and high readings. In contrast, O₃ shows no variation at all – every recorded value is exactly 2.7 µg/m³. PM10 exhibits a tighter band, from 19.6 to 26.8 µg/m³, with the median close to the middle of that interval (≈23 µg/m³). The dataset also contains several older entries: three rows are older than seven days and six are older than thirty days, meaning that for some locations the picture may not reflect current conditions. Because coverage differs by pollutant and station, actual air quality in Angers can change across neighborhoods and over time, and the available data capture only a snapshot of those variations.

Data notes
The dataset for Angers includes four valid measurements and is refreshed regularly, having been updated within the past three days (last update 2026‑02‑10T05:00:00+00:00). These values represent a snapshot of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
