What the data includes

The dataset for Wateringen in South Holland contains five measurement rows drawn from a single monitoring station. All five pollutants measured at this location—PM1, PM2.5, relative humidity, temperature and the particle count UM003—are reported with the same timestamp of 2026-02-10 22:00 UTC, meaning the newest data are less than seven days old.

Because each pollutant appears only once in the record, there is no observed spread between minimum, median and maximum values. PM1 registers at 15.38 µg/m³, while PM2.5 shows a concentration of 29.46 µg/m³. Relative humidity is recorded at 65.24 %, temperature at 13.07 °C and the particle count UM003 at 851.69 particles per cm³. The identical “min‑med‑max” figures indicate that the current snapshot does not capture variability over time or across multiple sites within the city.

With only one station contributing data, the coverage is limited to a single point in Wateringen, so conditions elsewhere in the municipality may differ from what these numbers represent. Nevertheless, the information is recent and provides a concrete baseline for each of the five pollutants at the time of measurement.
