What the data includes
The dataset for Zwolle contains a single monitoring station that reports five pollutants: PM1, PM2.5, relative humidity, temperature and UM003 (particle count). All measurements come from the same row, so the station count is one. Each pollutant has exactly one recorded value, which also serves as its minimum, median and maximum because no additional rows are available. The most recent update for every parameter was on 2026-02-10 at 22:00 UTC, meaning the data are fresh within the last seven days but there are no older or future records to show any variation over time.
PM1 is reported as 17.078000005086263 µg/m³ and PM2.5 as 28.766333325703943 µg/m³, both with identical low‑high spreads because only one observation exists. Relative humidity stands at 63.09333330790202 % and temperature at 12.114500045776367 °C, again each presented as a single point estimate. The UM003 particle concentration is 931.8055002848308 particles/cm³, with no range to compare against.
Because the dataset consists of a solitary row, there is no statistical spread or trend information for any pollutant; the values represent a snapshot rather than a distribution. This limited coverage means that conditions in different neighbourhoods of Zwolle may differ from what the single station records at the time of measurement. Users should keep in mind that while the timestamps are recent, the lack of multiple observations restricts insight into daily or seasonal fluctuations for any of the listed pollutants.
