Air quality today

The air quality in Soria today is classified as Good. The main pollutant identified is PM2.5, fine particulate matter measured by the monitoring network. Recent data show a PM2.5 reference value of 1.8 µg/m³ and a PM10 reference value of 3.0 µg/m³, based on five valid measurements collected via OpenAQ.

Overall conditions meet the Good category criteria according to the latest assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Soria contains a single monitoring station that reports seven common air‑quality 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). All measurements are expressed in micrograms per cubic metre (µg/m³).

The most recent values for the five pollutants that were updated within the last week were recorded on 2026‑02‑09 at 15:00 UTC, showing CO 500.0 µg/m³, NO₂ 21.0 µg/m³, O₃ 67.0 µg/m³, PM₁₀ 3.0 µg/m³, PM₂.₅ 1.8 µg/m³ and SO₂ 5.0 µg/m³. In contrast, the CO reading dates back to 2023‑12‑28 at 12:00 UTC and the NO reading to 2024‑01‑29 at 23:00 UTC, indicating that those two pollutants have not been refreshed for several months.

Because there is only one row of data, the range for each pollutant collapses to a single value – the minimum, median and maximum are identical (for example, CO is consistently reported as 500.0 µg/m³). This lack of variability means the dataset cannot illustrate any temporal spread or fluctuations for Soria’s air quality. Moreover, while half of the pollutants have recent timestamps, the older CO and NO entries highlight uneven freshness across the measured suite.

Overall, the coverage is limited to a single monitoring point, with most pollutants showing up‑to‑date measurements but two key gases remaining outdated. Users should keep in mind that conditions can differ across neighborhoods and times, and the current data set does not capture such spatial or temporal diversity.

Data notes

The dataset for Soria includes five valid measurements and is updated within three days, with the most recent data recorded on 2026‑02‑09 at 15:00 UTC. These figures represent a snapshot of current conditions; air quality can differ across neighborhoods and change throughout the day, so local variations may not be fully captured in this summary.
