What the data includes

The dataset for Saint‑Jean‑de‑la‑Ruelle contains measurements for four pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter ≤ 10 µm (PM₁₀) and particulate matter ≤ 2.5 µm (PM₂.₅). All values are reported in micrograms per cubic metre (µg/m³). The city’s monitoring network is represented by a single measurement station, which contributes four rows of data—one for each pollutant.

The timestamps show that the NO reading is older, last recorded on 2024‑03‑11 09:00 UTC, while the NO₂, PM₁₀ and PM₂.5 values are more recent, each updated on 2026‑02‑10 15:00 UTC. This means three of the four pollutants have data that is fresh within the past few days, whereas the NO measurement is over a year old.

Across the available records the observed concentrations are identical to their respective medians, indicating no variation in the limited sample set. NO registers at 14.7 µg/m³, NO₂ at 7.9 µg/m³, PM₁₀ at 7.6 µg/m³ and PM₂.5 at 4.5 µg/m³; each pollutant’s minimum, median and maximum values are the same. Because only one station supplies data, spatial coverage across Saint‑Jean‑de‑la‑Ruelle is limited, and conditions can differ in other parts of the city or at times not captured by these timestamps.

Data notes

The data shown are based on three valid measurements and were updated within 3 days, with the latest reading recorded at 2026‑02‑10 15:00 UTC. 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.
