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 ’s‑Hertogenbosch contains a single monitoring location – Empel – which supplies one row of measurements for each of the five tracked variables: PM1, PM2.5, relative humidity, temperature and particle count (UM003). All values were recorded at the same moment, 2026‑02‑10 22:00 UTC, so the data are fresh within the last seven days for every pollutant.

PM1 is reported as 4.72 µg/m³, while PM2.5 measures 9.27 µg/m³; both figures are identical across their minimum, median and maximum because only one observation exists. Relative humidity stands at 65.16 % and temperature at 13.04 °C, again with no variation in the dataset. The particle concentration (UM003) is 470.02 particles/cm³, also a single‑point value.

Because there is just one station row, the range for each pollutant collapses to that single reading – the minimum, median and 90th percentile are all the same. This means the current snapshot cannot reveal any spatial or temporal spread within the city; conditions may differ in other neighbourhoods or at other times. Nonetheless, the data are up‑to‑date, with the latest timestamp less than a week old for every parameter, providing a reliable recent picture of air quality at Empel.
