Air quality today

The air quality in Ciudad Real today is classified as Good. The primary pollutant identified is PM2.5, fine particulate matter that is being monitored alongside PM10. Measurements from five valid sampling points show a PM2.5 reference value of 3.0 and a PM10 reference value of 2.0, indicating concentrations within the limits associated with this category.

Data are displayed via OpenAQ and reflect the current assessment for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Ciudad Real contains a single monitoring station that reports six pollutants: nitrogen monoxide (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 are fairly fresh for five of the six pollutants, with updates recorded on 2026‑02‑09 between 12:00 and 15:00 UTC. Only NO is older, last updated on 2024‑02‑13 00:00 UTC, which means its reading is more than two years out of date while the others reflect conditions from just a few days ago. The station provides a single data point for each pollutant, so there is no range of values across multiple locations or times; the minimum, median and maximum are identical for every metric (NO 3.0, NO2 2.0, O3 70.0, PM10 2.0, PM2.5 3.0, SO2 2.0 µg/m³).

Because the dataset consists of one row per pollutant, there is no variability to describe and the coverage is limited to this lone site. The timestamps show that five pollutants are up‑to‑date within the last seven days, while NO remains an outlier with older data. Consequently, the current snapshot gives a very narrow view of air quality in Ciudad Real; conditions can differ across neighborhoods or over time, but those differences are not captured by the available measurements.
