Air quality today

The air quality in Lleida today is classified as Good. The primary pollutant measured is PM2.5, with a reference concentration of 9.0 µg/m³, while the accompanying PM10 level stands at 13.0 µg/m³ based on eight valid observations.

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

What the data includes

The air‑quality dataset for Lleida currently contains eight measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM2.5) and sulphur dioxide (SO₂). All values come from a single monitoring site, identified as LLEIDA (IRURITA – PIUS XII), so the dataset represents one location rather than a network of stations across the city.

Each pollutant shows a single recorded concentration that is identical for its minimum, median and maximum, indicating no observed variation within the reporting period. CO registers at 200 µg/m³, NO at 3 µg/m³, NO₂ at 11 µg/m³, NOX at 15 µg/m³, O₃ at 24 µg/m³, PM10 at 13 µg/m³, PM2.5 at 9 µg/m³ and SO₂ also at 3 µg/m³. Because the dataset contains only one row per pollutant, statistical spread such as inter‑quartile ranges cannot be derived; the reported values are effectively point measurements.

All eight readings were last updated on 2026-02-10 03:00 UTC, which falls within the “updated within 7 days” freshness category. This means the data are recent, but because they originate from a single site and represent only one moment in time, they do not capture spatial or temporal variability that may exist elsewhere in Lleida. Users should keep in mind that conditions can differ across neighborhoods and over the course of a day, even though the current dataset provides an up‑to‑date snapshot for the monitored location.

Data notes

The data shown for Lleida are based on eight valid measurements and were refreshed recently, with the latest update recorded on 2026‑02‑10 at 03:00 UTC (updated within three days). This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
