Air quality today

The air quality in Belfort today is classified as Moderate. The primary pollutant measured is PM2.5, with a reference concentration of 14.3 µg/m³, while the accompanying PM10 level stands at 16.7 µg/m³ based on five valid observations.

Data are shown via OpenAQ and reflect the current monitoring results for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Belfort’s air‑quality record draws on seven data rows collected at two monitoring sites. The dataset includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀) and particulate matter ≤ 2.5 µm (PM₂.₅). Freshness varies across the series: the most recent NO₂ reading was logged on 2026‑02‑10 at 15:00 UTC, O₃ shares the same timestamp, while PM₁₀ and PM₂.₅ were last updated on 2026‑02‑09 at 03:00 UTC. The NO measurement is considerably older, dated 2024‑03‑11 at 09:00 UTC, making it the only value that falls outside the “updated within three days” window.

Across the recent entries, concentrations show a narrow spread for most pollutants. NO₂ values range from 8.9 to 9.2 µg/m³ with a median of 9.05 µg/m³, indicating very little day‑to‑day variation at the centre site. O₃ is reported as a single value of 74.2 µg/m³, while PM₂.5 also appears as a solitary measurement of 14.3 µg/m³. In contrast, PM₁₀ displays a broader range, from 3.8 up to 16.7 µg/m³ and a median of 10.25 µg/m³, suggesting more fluctuation in coarse particle levels across the monitoring period.

The dataset’s composition highlights uneven coverage: three pollutants (NO₂, O₃, PM₁₀) have two recent rows each, whereas PM₂.5 is represented by only one row and NO by a single older entry. Consequently, while the latest snapshots give a clear picture of current conditions for most gases and fine particles, the limited number of stations and the age of the NO data mean that city‑wide air quality can still differ by location and time beyond what these rows capture.

Data notes

The data shown for Belfort reflects five valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 15:00 UTC; it is therefore considered “Updated within 3 days.” This snapshot provides a current view of ambient air quality, but conditions can differ across neighborhoods and change throughout the day, so values may vary locally and temporally.
