Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Mairena del Aljarafe contains a single monitoring station, so each pollutant is represented by one row of data. Five pollutants are recorded: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and sulfur dioxide (SO₂). The most recent observation overall dates from 2026‑02‑09 03:00 UTC, which applies to NO₂, O₃, PM₁₀ and SO₂; the NO value is older, last updated on 2024‑02‑21 00:00 UTC. All four of those newer readings are flagged as “Updated within 7 days,” indicating they are relatively fresh.
Across the pollutants the measured values show very little variation because each metric has a single reported figure. NO is consistently 1.0 µg/m³, NO₂ registers at 0.0 µg/m³, O₃ stands out at 81.0 µg/m³, PM₁₀ is recorded as 0.0 µg/m³ and SO₂ appears at 2.0 µg/m³. Because there is only one data point per pollutant, the minimum, median and maximum are identical for each, so no spread can be assessed from this snapshot.
The coverage is uneven in terms of timeliness: while four pollutants have measurements from early February 2026, the NO reading is more than two years old. This mix of recent and outdated timestamps means that the current picture may not capture short‑term fluctuations, especially for NO. Users should keep in mind that conditions can differ across neighborhoods and over time, and the single‑station snapshot provides only a limited view of air quality in Mairena del Aljarafe.
