What the data includes

The Baarn air‑quality record draws on five recent observations from a single monitoring site, all captured at the same moment on 2026‑02‑10 22:00 UTC and flagged as “updated within 7 days.” The dataset includes measurements for five pollutants: PM1, PM2.5, relative humidity, temperature and UM003 (particle count). Because every pollutant entry shares the identical timestamp, the data represent a snapshot rather than an ongoing series, so any assessment of variability must be based on the single reported value for each metric.

For this snapshot, PM1 registers 14.1525 µg/m³, while PM2.5 is measured at 26.6328 µg/m³; both figures are presented as the minimum, median and maximum because no other readings are available from the same day. Relative humidity stands at 69.5398 % and temperature at 11.3062 °C, again each reported as a solitary point value. The UM003 particle concentration is recorded as 791.7080 particles/cm³, with no spread indicated across time or location.

The uniformity of timestamps means the dataset does not capture temporal changes or spatial differences within Baarn; any fluctuations that might occur later in the day or at other sites are absent. Consequently, while the snapshot offers a clear picture of conditions at one specific moment, it cannot illustrate trends, diurnal cycles or neighborhood‑level variation. Users should keep in mind that air quality can shift throughout the day and across different parts of the city, so this single‑timepoint record provides only a limited view of Baarn’s overall atmospheric state.

Data notes

The data shown for Baarn reflects five valid measurements and was updated within 3 days, with the latest reading recorded on 2026‑02‑10 at 22:00 UTC. This snapshot provides a current view of air quality across the city, but conditions can differ by specific neighbourhoods and change throughout the day. Consequently, values may not represent every location or moment in Baarn.
