Air quality today
The air quality today in Montbéliard is classified as Good. The primary pollutant identified for the current assessment is PM2.5 (fine particles).
Measurements show a PM2.5 reference value of 0.6 and a PM10 reference value of 1.2, based on three valid observations recorded via OpenAQ. 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 Montbéliard air‑quality record draws from a single monitoring site that supplies five separate pollutant measurements. The dataset therefore contains one row per pollutant, giving a total of five rows of data for the city. All five common urban pollutants are represented: 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).
The timestamps show a mixed picture of data freshness. The most recent entry is for NO₂, PM10 and PM2.5, each last updated on 2026‑02‑10 at 15:00 UTC, indicating that these three pollutants have been refreshed within the past few days. Ozone’s latest value dates back to 2025‑08‑28 10:00 UTC, while the NO measurement is older still, recorded on 2024‑03‑11 09:00 UTC. Thus, half of the pollutants have very recent values, but two remain over a year old.
Across the five measurements the observed concentrations are identical to their median and extreme values because each pollutant has only one reported figure. NO registers at 49.6 µg/m³, NO₂ at 6.7 µg/m³, O₃ at 38.0 µg/m³, PM10 at 1.2 µg/m³ and PM2.5 at 0.6 µg/m³. Because there is no variation within each pollutant’s series, the dataset cannot describe a range or spread for any of them.
Overall, the data set provides complete coverage of the five key pollutants but relies on a single monitoring location, and the recency of the measurements varies considerably. Users should keep in mind that conditions can differ across Montbéliard and may change between the dates of the latest updates.

Data notes
The data shown for Montbéliard are based on three valid measurements and were refreshed recently, with the latest update recorded on 2026‑02‑10 at 15:00 UTC (updated within 3 days). These values provide a snapshot of current conditions but air quality can differ across neighborhoods and change throughout the day, so local variations may not be fully captured in this summary.
