Air quality today

The overall air quality today in San Bartolomé de Tirajana is classified as Good. The main pollutant identified is PM2.5 (fine particles). Twelve valid measurements were used to calculate the current assessment, and the data are shown via OpenAQ, which compiles information from local monitoring stations. The assessment follows the criteria set for the region and reflects current atmospheric conditions.

The PM2.5 reference value derived from these measurements is 4.975 µg/m³, and the PM10 reference value is 11.0 µg/m³. These figures represent the average concentrations reported for the day. Both pollutants are measured in micrograms per cubic meter, a standard unit for ambient air monitoring.

What the data includes

The OpenAQ feed for San Bartolomé de Tirajana contains 24 recent observations drawn from four monitoring sites. Measured constituents include carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter of 10 µm (PM₁₀), 2.5 µm (PM₂.₅) and 1 µm (PM₁) size fractions, and sulfur dioxide (SO₂). The dataset also lists relative humidity, temperature and a sensor code (UM003), but no values for those three variables are present in the current rows.

The newest timestamps are from early February 2026, with most pollutants refreshed on 2026‑02‑09 15:00 UTC or 2026‑02‑10 20:00 UTC. CO, NO₂, O₃, SO₂ and PM₁₀ were all last updated on 2026‑02‑09 15:00 UTC, while PM₂.₅ and PM₁ show the most recent update on 2026‑02‑10 20:00 UTC. NO is an outlier, with its only record dated 2024‑02‑27 00:00 UTC, indicating a gap in recent coverage for that gas. Across the four stations, PM₁₀ values span from roughly 8 µg/m³ to 30 µg/m³, with a median of 12 µg/m³; PM₂.₅ ranges from 2 µg/m³ to 34 µg/m³, median about 5.5 µg/m³. Ozone peaks at 89 µg/m³, while sulfur dioxide remains constant at 4 µg/m³ in all recent readings. CO is reported at a single value of 400 µg/m³ from the Castillo del Romeral site.

Coverage is uneven: some pollutants such as CO, PM₁ and PM₂.₅ are represented by a single station, whereas others like PM₁₀ and NO₂ have data from all four sites. Because several variables lack recent or any measurements, the picture of air quality can differ across neighborhoods and times, and the available figures reflect only the locations and moments captured in the current dataset.
