What the data includes

The Vianen air‑quality record draws on five recent data rows collected from a single monitoring site, all of which were last updated on 2026‑02‑10 at 22:00 UTC. The dataset supplies measurements for five pollutants: PM1, PM2.5, relative humidity, temperature and the particle count labelled UM003. For each pollutant the most recent reading is also the only value recorded, so the minimum, median, maximum and percentile figures are identical.

PM1 registers at 20.221999963124595 µg/m³, while PM2.5 shows a concentration of 31.186166699727377 µg/m³. Relative humidity stands at 69.85166702270509 % and the ambient temperature is 11.602000125249228 °C. The UM003 sensor reports 3 261.7749999999996 particles per cubic centimetre. Because there is only one observation per pollutant, the data does not reveal any spread or trend over time; each metric reflects a single snapshot rather than a range of values.

All five measurements are fresh, having been recorded within the last seven days, which means the information represents conditions as they were on 2026‑02‑10. However, with only one monitoring location in Vianen, spatial coverage is limited and may not capture variations across different neighbourhoods or micro‑environments. The uniform timestamp also indicates that no historical series is currently available for comparison, so any assessment of how these values relate to typical conditions must consider the lack of broader temporal context.

Data notes

The data shown for Vianen is based on five valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC; it is therefore considered “Updated within 3 days.” While this snapshot reflects current conditions across the city, air quality can differ by specific neighbourhoods and change throughout the day, so local variations may occur.
