Air quality today

The air quality in Tudela today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 2.0 µg/m³ and a PM10 reference value of 5.0 µg/m³, based on sixteen valid observations collected via OpenAQ.

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

What the data includes

The Tudela air‑quality dataset currently contains measurements for seven pollutants – carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulphur dioxide (SO₂). The data come from three monitoring stations and a total of 24 individual rows, each representing a separate reading. Freshness varies across the suite: the most recent NO₂, O₃, PM10 and PM2.5 values were recorded on 2026‑02‑09 15:00 UTC (NO₂ = 11.0 µg/m³, O₃ = 40.0 µg/m³, PM10 = 5.0 µg/m³, PM2.5 = 2.0 µg/m³ at the TUDELA II site), while the latest NO reading dates back to 2024‑02‑22 00:00 UTC (1.0 µg/m³ at TUDELA). SO₂ was last updated on 2026‑02‑06 13:00 UTC (2.0 µg/m³ at TUDELA) and CO’s most recent entry is from 2023‑02‑15 10:00 UTC (100.0 µg/m³ at ES1661A).

Across the recent seven‑day window, NO₂ values range from a low of 3.0 to a high of 11.0 µg/m³, with a median of 9.0 µg/m³; O₃ spans 1.0–80.0 µg/m³ (median 42.0), while PM10 varies between 1.0 and 23.0 µg/m³ (median 5.0). The particulate matter measurements are tightly clustered, whereas ozone shows a much broader spread. In contrast, the older NO data cover only 1.0–3.0 µg/m³ (median 1.0) and SO₂ is limited to a single value of 2.0 µg/m³, reflecting sparse recent sampling for these gases.

Overall, the dataset offers a fairly up‑to‑date picture for NO₂, O₃, PM10 and PM2.5 but relies on older entries for NO, SO₂ and CO. Because the observations come from just three stations, spatial variation within Tudela is not fully captured; conditions can differ across neighborhoods and times that are not represented in the current rows.

Data notes

The data shown for Tudela are based on 16 valid measurements and were refreshed recently, Updated within 3 days (last update: 2026‑02‑09T15:00:00+00:00). This snapshot reflects conditions at the time of collection; air quality can vary across different neighbourhoods and moments throughout the day, so values may not represent every location or instant in the city.
