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 Las Rozas de Madrid draws on seven data rows collected at a single monitoring site, LAS ROZAS. Four pollutants are represented: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter ≤ 10 µm (PM10). The most recent measurements for NO₂, O₃ and PM10 were all uploaded on 2026‑02‑09 at 15:00 UTC, so the latest values are fresh within the past week. In contrast, the only NO reading dates back to 2024‑02‑28 at 23:00 UTC and is flagged as old data, indicating a gap of two years for that pollutant.
Across the three newer pollutants the observed concentrations are tightly clustered. NO₂ shows a single value of 8.0 µg/m³, with both its minimum and maximum equal to the median, reflecting no variation in the recent row set. O₃ ranges from 62.0 to 67.0 µg/m³, with a median of 64.5 µg/m³; the inter‑percentile spread (10th–90th) is narrow at roughly 4 µg/m³, suggesting limited fluctuation during the sampled period. PM10 values sit between 4.0 and 5.0 µg/m³, median 4.5 µg/m³, again with a small spread of about 1 µg/m³.
The dataset therefore provides a concise snapshot: one well‑maintained station supplies recent, consistent readings for three key pollutants, while NO coverage is sparse and dated. Because the information comes from only one location, conditions elsewhere in Las Rozas de Madrid may differ, especially at times or places not captured by this limited set of rows.
