Air quality today

The air quality in Patones 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 ten valid observations reported through OpenAQ.

Overall conditions meet the criteria for the Good category according to the provided assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Patones’ air‑quality record is built from two monitoring stations that together report seven key pollutants: carbon monoxide (CO), nitrogen oxides (NO and NO₂), ozone (O₃), particulate matter of both size fractions (PM₁₀ and PM₂.₅) and sulphur dioxide (SO₂). The most recent data for CO, NO₂, O₃, PM₁₀, PM₂.₅ and SO₂ were all uploaded on 2026‑02‑09 at 15:00 UTC, while the lone NO reading dates back to 2024‑02‑28 at 23:00 UTC, classifying it as older information.

Across the recent set, CO peaks at 600 µg/m³ with a narrow spread – the minimum recorded value is 500 µg/m³ and the median matches the maximum at 600 µg/m³. NO₂ shows a tighter range from 5 to 8 µg/m³, centred around a median of 7 µg/m³; O₃ varies between 58 and 69 µg/m³ with a median of 62 µg/m³. Particulate matter is consistently low: PM₁₀ ranges from 1 to 14 µg/m³ (median 1) and PM₂.₅ from 1 to 10 µg/m³ (median 1). SO₂ is recorded between 2 and 3 µg/m³, median 3 µg/m³. These figures illustrate that, for most pollutants, the recent observations cluster tightly around their medians, while CO stands out with a higher and less variable concentration.

The dataset’s freshness is uneven. Five of the seven pollutants have updates within the past week, indicating current conditions are well represented for those species. In contrast, NO data is over two years old, meaning any assessment that relies on nitrogen monoxide must acknowledge this gap. With only two stations contributing, spatial coverage is limited; variations in air quality across different parts of Patones may not be captured fully, especially for pollutants with older or sparse records.
