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 dataset for Roussillon contains four pollutant measurements collected from a single monitoring station, covering nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3) and particulate matter 10 µm or less (PM10). All values are expressed in micrograms per cubic metre. The most recent record for NO dates back to 2024‑03‑11 09:00 UTC, while the other three pollutants have been updated more recently: NO2 and O3 were last reported on 2026‑02‑10 15:00 UTC and PM10 on 2026‑02‑09 03:00 UTC. This means that three of the four measurements are fresh within the past three to seven days, whereas the NO reading is over a year old.
Across the four pollutants the observed concentrations are identical to their single recorded values, giving a clear picture of the current snapshot but no indication of variability. The median, minimum and maximum for each pollutant are all the same: NO 6.0 µg/m³, NO2 11.3 µg/m³, O3 53.4 µg/m³ and PM10 19.8 µg/m³. Because only one station contributes data, there is no spread or percentile range to describe; the 10th and 90th percentiles match the single value for each pollutant.
The coverage therefore consists of a solitary monitoring point, providing up‑to‑date information for three pollutants while the NO figure remains dated. As a result, the dataset offers a concise but limited view of air quality in Roussillon; conditions can differ across neighbourhoods and times that are not captured by this single‑station snapshot.
