Air quality today
The air quality in Sant Esteve de la Sarga today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 1.0 and a PM10 reference value of 1.0, based on six valid observations.
Overall conditions meet the criteria for the Good category according to OpenAQ data. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
Sant Esteve de la Sarga’s OpenAQ feed contains eight measured pollutants: carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO2), total nitrogen oxides (NOX), ozone (O3), particulate matter 10 µm (PM10), particulate matter 2.5 µm (PM2.5) and sulfur dioxide (SO2). All data come from a single monitoring station, identified as MONTSEC (OAM), so the dataset represents one row per pollutant.
The most recent observations are from 2026‑02‑10 03:00 UTC for CO, NO, NO2, NOX, O3, PM10 and PM2.5, while SO2 is older, last recorded on 2026‑01‑15 16:00 UTC. This means that fresh data (within the past week) are available for seven of the eight pollutants, but sulfur dioxide information is over three weeks old. Across the board the reported values show no variation: CO registers a single reading of 400.0 µg/m³, each nitrogen‑related gas records 1.0 µg/m³, O3 is 79.0 µg/m³, both PM fractions are 1.0 µg/m³ and SO2 stands at 25.0 µg/m³. Consequently the minimum, median and maximum values are identical for every pollutant, indicating a lack of observed range in this limited dataset.
Because only one monitoring location contributes data, spatial coverage across Sant Esteve de la Sarga is minimal; conditions elsewhere in the city may differ from those captured at MONTSEC (OAM). The dataset also shows an uneven temporal profile: seven pollutants have very recent timestamps, whereas SO2 remains outdated. Users should keep in mind that the current snapshot reflects a single point in time and place, and broader monitoring would be needed to capture variability throughout the city.
