What the data includes

The dataset for Vila do Conde contains eight recorded rows drawn from two monitoring sites and provides values for eight measured parameters: nitrogen dioxide (NO₂), ozone (O₃), particulate matter 1 (PM₁), particulate matter 10 (PM₁₀), particulate matter 2.5 (PM₂.5), relative humidity, temperature and particle count (UM003). The most recent observations were uploaded on 2026‑02‑10 at 21:00 UTC for NO₂, O₃ and PM₁₀, while the remaining five parameters were last updated on 2025‑12‑30 at 10:00 UTC. This means that half of the variables reflect data that is more than a month old, whereas the other half are refreshed within the past week.

Across the eight rows the recorded values show very little variation because each pollutant has only a single reported figure. NO₂ registers 3.6 µg/m³, O₃ 44.0 µg/m³ and PM₁₀ 25.0 µg/m³ at the Mindelo‑Vila do Conde site. At the Modivas site the older entries list PM₁ at 29.64 µg/m³, PM₂.5 at 43.84 µg/m³, relative humidity at 51.40 % , temperature at 20.49 °C and UM003 at 2 455.5 particles/cm³. Because each pollutant is represented by a single measurement, the median, minimum and maximum values are identical for every parameter.

The mix of fresh and dated timestamps highlights an uneven coverage: three pollutants have up‑to‑date readings while the rest rely on older data, so current air‑quality conditions in Vila do Conde may differ from what is shown here. Users should keep in mind that measurements come from only two locations, limiting spatial detail across the city.
