What the data includes

The dataset for Romans‑sur‑Isère contains a single monitoring station that reports five common air‑quality variables: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀) and particulate matter ≤ 2.5 µm (PM₂.₅). All measurements are expressed in micrograms per cubic metre (µg/m³).

The most recent values for NO and NO₂ date from 2024‑01‑05 10:00 UTC, while O₃, PM₁₀ and PM₂.5 were last updated on 2026‑02‑10 15:00 UTC, showing that half of the pollutants have data refreshed within the past three days whereas the other half are over two years old. For each pollutant the recorded range is a single point: NO = 7.6 µg/m³ (min = max = median), NO₂ = 28.7 µg/m³, O₃ = 43.0 µg/m³, PM₁₀ = 9.6 µg/m³ and PM₂.5 = 7.4 µg/m³. Because each series contains only one observation, there is no spread to describe beyond the identical minimum, median and maximum values.

With just one row of data, coverage across the city is limited; conditions can differ in other neighbourhoods or at different times of day that are not captured here. The dataset also includes three rows classified as “old” (more than three days old) and two rows marked as “unknown”, indicating that a portion of the historical record lacks recent updates. Consequently, while the available numbers give a snapshot of current concentrations for the five pollutants at the single monitoring point, they do not reflect spatial or temporal variability throughout Romans‑sur‑Isère.

Data notes

The current dataset for Romans‑sur‑Isère includes three valid measurements and is updated within 3 days, with the latest values recorded at 2026‑02‑10T15:00:00+00:00. These figures represent a snapshot of ambient conditions across the city; air quality can differ by specific neighbourhoods, micro‑environments and time of day, so local variations may not be captured in this summary.
