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 Steenokkerzeel air‑quality dataset currently contains three measured pollutants – nitrogen dioxide (NO2), particulate matter up to 10 µm (PM10) and fine particulate matter up to 2.5 µm (PM2.5). All data come from a single monitoring location identified as “40SZ05 – STEENOKKERZ”, so the station count is two rows for NO2 and one row each for PM10 and PM2.5, giving a total of four recorded rows.
The most recent values were all uploaded on 2026‑02‑10 at 17:00 UTC, which means every pollutant in this set has been refreshed within the last three days. For NO2 the observed range spans from a low of 9.5 µg/m³ to a high of 16.5 µg/m³, with a median of 13.0 µg/m³ and the central 80 % of readings falling between roughly 10.2 and 15.8 µg/m³. In contrast, PM10 shows a single constant reading of 3.8 µg/m³, and PM2.5 also reports a single value of 2.15875 µg/m³; both have identical minimum, median and maximum values because only one measurement is available for each.
Because the dataset relies on just one sensor location, the spatial coverage across Steenokkerzeel is limited to that point, and the variability information differs markedly between pollutants – NO2 provides a modest spread of values while PM10 and PM2.5 offer no observed variation at all. Nevertheless, the timestamps indicate that the data are up‑to‑date, so the figures reflect the city’s air quality as measured at that specific site on 2026‑02‑10 17:00 UTC.
