Air quality today

The air quality in Sabadell today is classified as Good. The primary pollutant identified is PM10, with a measured reference value of 7.0 micrograms per cubic metre based on two valid observations reported through OpenAQ.

These measurements indicate that the current particulate matter levels are within the range associated with the Good category. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Sabadell air‑quality dataset contains measurements for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃) and particulate matter 10 µm or smaller (PM10). The data come from nine rows recorded at two monitoring sites, so each pollutant is not necessarily represented by the same number of observations.

The most recent values are fairly mixed. NO was last updated on 2024-02-21 00:00 UTC, while NO₂ and PM10 have fresh entries from 2026-02-09 15:00 UTC, both within the past week. O₃ and NOX are older, with their latest timestamps on 2023-04-05 02:00 UTC, indicating that for these gases the available data are more than a year out of date.

Across the pollutants the observed concentrations span modest ranges. NO varies from 3 µg/m³ to 6 µg/m³ with a median of 4.5 µg/m³; NO₂ shows a broader spread, ranging between 9 µg/m³ and 24 µg/m³ and a median of 16.5 µg/m³. O₃ values are the most variable, from 3 µg/m³ up to 56 µg/m³ with a median near 29.5 µg/m³. PM10 is relatively low‑level, ranging 7–12 µg/m³ and centering around 9.5 µg/m³. NOX is constant in this set at 13 µg/m³.

Because the dataset includes only two stations, spatial coverage within Sabadell is limited, and the age of some measurements (especially O₃ and NOX) means that current conditions may differ from what is recorded here. Users should keep in mind that air quality can change across neighborhoods and over time, and the available data represent a snapshot rather than a complete picture of the city’s atmosphere.
