What the data includes

The dataset for Segovia includes measurements of six common air‑quality gases and particles: carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and sulphur dioxide (SO₂). All values come from a single monitoring location, giving six rows of data in total.

The most recent observations are from 2026‑02‑09 15:00 UTC for NO₂, O₃, PM₁₀ and SO₂, showing that half of the pollutants have been updated within the last week. The NO reading is older, dated 2024‑01‑29 23:00 UTC, while the CO measurement is the oldest, recorded on 2020‑12‑30 10:00 UTC and flagged as “old data”. Because the timestamps differ, the overall freshness of the dataset is mixed: recent updates exist for four pollutants but two remain several years out of date.

Each pollutant shows a single reported value with no variation across the recorded period – the minimum, median and maximum are identical (CO 200 µg/m³, NO 2 µg/m³, NO₂ 27 µg/m³, O₃ 50 µg/m³, PM₁₀ 13 µg/m³, SO₂ 3 µg/m³). This lack of spread indicates that the data set captures only one snapshot per pollutant rather than a range of measurements. Consequently, while the recent timestamps give a glimpse of current conditions for four pollutants, the limited number of stations and the static values mean the picture is incomplete and may not reflect variations across different parts of Segovia or over time.
