What the data includes

The Gouda air‑quality dataset draws from a single monitoring location – Gouda Goverwelle – giving a total of five recorded rows across the city’s OpenAQ feed. All five pollutants are represented: fine particles measured as PM1 at 12.19 µg/m³, PM2.5 at 24.04 µg/m³, relative humidity at 63.40 %, temperature at 13.54 °C, and particle number concentration (UM003) at 784.70 particles/cm³. Each of these values comes from the same timestamp, 2026‑02‑10 22:00 UTC, which is flagged as “updated within 7 days,” indicating that the data are recent but not real‑time.

Because every pollutant entry shares identical minimum, median and maximum figures, there is no observable variability in this snapshot; each metric reports a single point rather than a range. This uniformity reflects the limited spatial coverage – only one sensor contributes to all five parameters – so the numbers describe conditions at that specific site rather than city‑wide averages. The freshness of the data is consistent across pollutants, with the most recent measurement recorded on 2026‑02‑10, meaning users can rely on a common reference time but should be aware that conditions elsewhere in Gouda may differ.

In practical terms, the dataset offers a concise view of current air quality and related environmental factors at Gouda Goverwelle. The single‑station approach provides up‑to‑date readings for each pollutant, yet the lack of multiple locations or historical spread limits insight into broader temporal trends or spatial variations within the city. Users should consider these constraints when interpreting the figures, recognizing that they capture a momentary snapshot rather than a comprehensive picture of Gouda’s overall air quality.
