Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The air‑quality record for Marignane draws on eight measurement rows collected from two monitoring sites. All six key pollutants tracked by OpenAQ are represented – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulfur dioxide (SO₂). Freshness varies considerably: the most recent updates are from 2026‑02‑10 15:00 UTC for NO₂, PM₁₀ and PM₂.₅, while CO and SO₂ still reflect data last recorded on 2017‑07‑18 20:00 UTC. The NO reading is dated 2024‑03‑11 07:00 UTC, making it the only older but not ancient entry among the newer set.
Across the recent three‑day window, NO₂ values range from a low of 15.5 µg/m³ to a high of 21.5 µg/m³, with a median of 18.5 µg/m³ and the central 80 % of observations falling between roughly 16.1 and 20.9 µg/m³. PM₁₀ shows a broader spread: minimum 6.7 µg/m³, maximum 19.5 µg/m³, median 13.1 µg/m³ and the 10th‑90th percentile band from about 8.0 to 18.2 µg/m³. In contrast, PM₂.₅ is remarkably stable at a single reported value of 4.1 µg/m³, while NO sits at a constant 48.5 µg/m³. The legacy CO reading remains fixed at 200.0 µg/m³ and SO₂ registers zero across its lone entry.
Overall the dataset leans heavily toward recent measurements for three pollutants but relies on very old data for two others, indicating uneven temporal coverage. With only two stations feeding eight rows, spatial representation is limited; conditions can differ across neighborhoods and times not captured by these snapshots.

Data notes
The data shown reflects three valid measurements and is updated within 3 days, with the latest reading recorded on 2026‑02‑10 at 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 captured in this brief overview.
