Mr. Duck’s Air Quality Score
Good air today for Sondika, Autonomous Community of the Basque Country, Spain
This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Sondika today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 6.0 and a PM10 reference value of 3.0, based on three valid observations.
Data is shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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 Sondika includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). These values come from a total of seven rows, but only two distinct monitoring stations contribute recent data: the SANGRONIZ site supplies the latest NO₂, PM₁₀ and PM₂.₅ readings, while the ES1595A station provides the most recent NO measurement.
The freshest observations were recorded on 2026‑02‑09 at 15:00 UTC for NO₂ (8.0 µg/m³) and at 10:00 UTC the same day for both PM₁₀ (3.0 µg/m³) and PM₂.₅ (6.0 µg/m³). The NO value is older, last updated on 2024‑01‑16 at 23:00 UTC (1.0 µg/m³). Across the recent data, the range for NO₂ spans from a minimum of 8.0 to a maximum of 12.0 µg/m³, with a median of 10.0 µg/m³; PM₁₀ varies between 3.0 and 20.0 µg/m³ (median 11.5 µg/m³); PM₂.₅ is tightly clustered from 6.0 to 8.0 µg/m³ (median 7.0 µg/m³). The 10th‑percentile values are close to the minima for each pollutant, indicating that low readings are not outliers.
Because only two stations contribute recent measurements, coverage is limited and uneven: three pollutants have up‑to‑date data from a single site, while NO relies on an older record from a different location. Consequently, the available snapshot reflects conditions at specific points rather than a comprehensive citywide picture, and actual air quality in other parts of Sondika may differ from these values.
