What the data includes

The dataset for Dijon 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). Data come from a total of seven monitoring rows, but the number of recent observations varies by pollutant. The most up‑to‑date values are for NO₂, O₃, PM10 and PM2.5, all refreshed within the last three to seven days; the latest timestamps are 2026‑02‑10 15:00 UTC for NO₂ and O₃, and 2026‑02‑09 03:00 UTC for both PM10 and PM2.5. In contrast, the NO data are older, with the newest reading dated 2024‑03‑11 09:00 UTC, indicating that recent information for this gas is limited.

Across the pollutants, concentration ranges differ markedly. NO₂ values span from a low of 1.9 µg/m³ to a high of 54.8 µg/m³, with a median around 21.3 µg/m³; O₃ shows a narrower band between 17.6 and 52.2 µg/m³, median 50.7 µg/m³. Particulate matter is generally low, with PM10 ranging from 8.0 to 27.5 µg/m³ (median 8.8) and PM2.5 from 5.6 to 19.4 µg/m³ (median 9.2). NO exhibits a broader spread, from 9.0 up to 80.5 µg/m³ and a median of 40.0 µg/m³.

Overall, the dataset provides recent coverage for four of the five pollutants but relies on older data for NO, and only seven rows contribute to the city’s picture. Consequently, while the available numbers give a snapshot of current conditions at specific sites, they do not capture the full spatial or temporal variability that may exist across Dijon.

Data notes

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