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 Ardrossan air‑quality record includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and fine particulate matter (PM₂.5). All of these come from a single monitoring station, giving a total of four data rows for the city. Each pollutant was last reported on 2026‑02‑10 at 22:00 UTC, which falls within the “updated within three days” freshness window, so the information reflects very recent conditions.
Across the dataset the observed values show no variation: NO is consistently recorded at 0.003 ppm, NO₂ at 0.005 ppm, O₃ at 0.034 ppm and PM₂.5 at 2.1 µg/m³. For every pollutant the minimum, median, 10th percentile, 90th percentile and maximum are identical, indicating that only a single measurement snapshot is available rather than a range of readings over time. Because there is just one station contributing data, the coverage is limited to the immediate vicinity of that sensor; conditions elsewhere in Ardrossan may differ.
In summary, the city’s public air‑quality page currently offers four pollutants measured at one location, with all values freshly updated but lacking temporal depth or spatial breadth. Users should keep in mind that this snapshot represents a specific point in time and place, and broader patterns across Ardrossan cannot be inferred from the present dataset alone.
