Air quality today

The air quality in Chambéry today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 2.0 µg/m³ and a PM10 reference value of 3.5 µg/m³, based on six valid observations recorded via OpenAQ.

These values 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.

What the data includes

The dataset for Chambéry includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM₁₀) and particulate matter 2.5 µm or smaller (PM₂.₅). Data come from twelve individual rows collected at three monitoring stations, giving a modest spatial coverage across the city.

The most recent measurements are fairly fresh for most pollutants: NO was last recorded on 2024-03-11 09:00 UTC, while NO₂, PM₁₀, O₃ and PM₂.₅ all have updates from 2026-02-10 15:00 UTC, meaning the newest values are at most a few days old. However, the older timestamp for NO indicates that not every pollutant is updated with the same frequency, so recent conditions may be better represented by the latter four species.

Across the available rows, concentrations show a wide spread for some gases and a narrow range for others. NO varies from 4.1 µg/m³ up to 39.4 µg/m³, with a median of 27.9 µg/m³, indicating that peak values can be roughly nine times the minimum observed level. NO₂ is more tightly clustered between 5.2 and 20.2 µg/m³, median 15.2 µg/m³, while ozone ranges from 30.8 to 56.6 µg/m³ with a median of 43.7 µg/m³, reflecting moderate variability. Particulate matter shows the least variation: PM₁₀ spans 3.5‑9.2 µg/m³ (median 8.7 µg/m³) and PM₂.₅ is constant at 2.0 µg/m³ across all rows, suggesting limited detection of finer particles in this dataset.

Overall, the data provide recent snapshots for most pollutants but rely on a relatively small number of stations, so conditions can differ by neighbourhood and time of day. Users should keep in mind that the coverage is uneven—especially for NO, where older records dominate—and that the observed ranges represent only the moments captured by the sensors.

Data notes

The data shown for Chambéry are based on six valid measurements and were refreshed recently, with the latest update recorded at 2026‑02‑10T15:00:00+00:00 (updated within 3 days). This snapshot reflects conditions at the time of collection; air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
