What the data includes

The current station data listed for this city is focused on particulate matter (PM). Only one monitoring row is present for St Ouen, and it reports a single pollutant: PM2.5 measured in micrograms per cubic metre. The most recent reading was recorded at 2026-02-10 23:04 UTC, which falls within the “updated within 3 days” window, indicating relatively fresh data for this location.

All available values are identical across statistical summaries – the minimum, median, maximum, 10th percentile and 90th percentile all equal 5.7 µg/m³, with the reading taken at St Ouen’s Village. Because there is just one station and a single pollutant, the dataset offers limited spatial coverage and no comparative information across different parts of the city or other pollutants. Consequently, while the latest measurement is recent, it represents only a snapshot from one point in time and place; conditions elsewhere in St Ouen may differ.
