Air quality today

The air quality in Zaragoza today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 7.76 and a PM10 reference value of 29.34, based on 41 valid observations collected via OpenAQ.

These figures indicate that the monitored concentrations are within the range associated with the Good category for this location. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Zaragoza’s OpenAQ feed currently includes data for seven pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). The dataset draws from eight monitoring stations, providing a modest spatial coverage across the city. For most pollutants the latest readings are very recent, having been recorded on 2026‑02‑09 at 15:00 UTC; only nitrogen oxide is based on an older entry from 2024‑03‑10, so its snapshot may not reflect current conditions.

The observed concentrations span a wide range. CO values vary from 100 µg/m³ up to 280 µg/m³, with a median of 170 µg/m³ and the most recent measurement at 190 µg/m³ in the CENTRO station. Ozone shows a minimum of 17.29 µg/m³, a maximum of 72.57 µg/m³ and a median near 60 µg/m³; the latest reading is 57.63 µg/m³ also from CENTRO. NO₂ ranges between 7.86 and 39.65 µg/m³ (median ≈ 14 µg/m³), with the newest value of 29.98 µg/m³ recorded at ROGER DE FLOR. Particulate matter follows a similar pattern: PM₁₀ values sit between 4.65 and 29.34 µg/m³ (median ≈ 15 µg/m³) with the latest measurement of 13.89 µg/m³ at ROGER DE FLOR, while PM₂.₅ is reported from only three stations, ranging from 1.0 to 7.76 µg/m³ (median ≈ 6.9 µg/m³) and the most recent value of 7.6 µg/m³ at EL PICARRAL. SO₂ is the least variable, spanning 1.17‑4.61 µg/m³ (median ≈ 3.2 µg/m³) with a current reading of 3.01 µg/m³ from CENTRO.

Overall, the dataset offers fresh information for six of the seven pollutants, but coverage is uneven: NO and PM₂.₅ are recorded at fewer stations, and the older NO data limits its usefulness for real‑time assessment. Consequently, while the available figures give a snapshot of air quality across Zaragoza, conditions can differ by neighbourhood and time, especially where monitoring is sparse or outdated.
