Air quality today

The air quality in Vila‑seca today falls into the Good category according to OpenAQ data. The primary pollutant identified is PM2.5, with a measured concentration of 5.0 µg/m³. In addition, PM10 levels are recorded at 10.0 µg/m³ based on 18 valid measurements.

These values indicate that the monitored particulate matter concentrations are within the reference limits set for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Vila‑seca air‑quality feed draws from three monitoring sites that together contribute 23 individual data rows. All eight pollutants tracked by the OpenAQ network – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃), sulphur dioxide (SO₂), and the three particulate fractions PM₁, PM₂·₅ and PM₁₀ – are represented in this city’s dataset. Every pollutant record was last refreshed on 2026‑02‑10 at 03:00 UTC, which falls within the “updated within seven days” freshness bucket, so the information is currently current.

The numeric spread varies markedly across substances. For gases, NO₂ peaks at 10 µg/m³ while its median sits at 3.5 µg/m³ and the lower‑decile is 2 µg/m³, indicating most recent readings cluster toward the low end of the observed range. O₃ shows a broader interval from 31 to 104 µg/m³, with a median of 82.5 µg/m³ and a 90th percentile near 98 µg/m³, suggesting higher variability in ozone levels across the sites. SO₂ is consistently low, ranging only between 1 and 5 µg/m³, with both its minimum and median equal to 1 µg/m³.

Particulate matter also displays differing patterns. PM₁₀ reaches a maximum of 10 µg/m³ but its typical value (median) is 7 µg/m³; the 10th percentile sits at about 6.2 µg/m³, so most recent measurements are clustered in the lower half of the observed spread. PM₂·₅ shows a tighter band from 1 to 5 µg/m³ with a median of 2 µg/m³, while PM₁ is reported as a single value of 5 µg/m³ across all rows. NO and NOX each appear as constant readings – 1 µg/m³ for NO and 10 µg/m³ for NOX – reflecting either limited variability or sparse sampling for these gases.

Overall, the dataset provides a complete snapshot of eight key pollutants from three stations, with all values refreshed on the same recent timestamp. The coverage is uneven: some compounds (NO₂, O₃, PM₁₀) show a noticeable range and median spread, whereas others (NO, NOX, SO₂, PM₁, PM₂·₅) are reported at single or very narrow values, indicating less variability in the current measurements.

Data notes

The dataset for Vila‑seca includes 18 valid measurements and is refreshed Updated within 3 days, with the latest values recorded on 2026‑02‑10T03:00:00+00:00. These figures represent a snapshot of conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
