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 air‑quality record for Arrasate / Mondragón includes four measured gases and particles – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂) and particulate matter up to 10 µm (PM₁₀). The dataset is built from two monitoring stations, providing a total of seven recent observations. Three of those rows have been refreshed within the last week, while the remaining four are older than seven days; the most recent update for CO, NO₂ and PM₁₀ was on 2026‑02‑09 15:00 UTC, and the lone NO reading dates back to 2024‑01‑16 23:00 UTC.
Across the recent entries, CO values range from 280 µg/m³ to 300 µg/m³, with a median of 290 µg/m³; the spread is narrow, as indicated by the 10th and 90th percentiles (282 µg/m³ and 298 µg/m³). NO₂ shows a broader interval, from 15 µg/m³ up to 24 µg/m³, median 19.5 µg/m³, and percentile limits at 15.9 µg/m³ and 23.1 µg/m³. PM₁₀ varies between 14 µg/m³ and 31 µg/m³, with a typical value of 22.5 µg/m³ and percentiles at 15.7 µg/m³ and 29.3 µg/m³. NO is represented by a single recent‑ish measurement of 1 µg/m³.
The coverage is uneven: CO, NO₂ and PM₁₀ have multiple fresh records, whereas NO relies on one older entry, limiting the ability to compare it directly with the other pollutants. Because only three rows are updated within the past week, the snapshot reflects conditions at a limited number of locations and times; air‑quality levels can differ across neighborhoods and over longer periods.
