Good air today for Jaén, Andalusia, Spain
This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Jaén today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 1.88 and a PM10 reference value of 13.8, based on eight valid observations collected via OpenAQ.
These figures indicate that the monitored concentrations are within the range associated with the Good category. 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
Jaén’s air‑quality dataset contains measurements for seven pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), sulphur dioxide (SO₂), particulate matter 10 µm or less (PM10) and particulate matter 2.5 µm or less (PM2.5). The data come from two monitoring stations, providing a total of twelve recent rows across all compounds.
The most up‑to‑date records were captured in early February 2026, with the latest timestamps ranging from 03:00 UTC for CO, NO₂, SO₂ and PM10/PM2.5 to 05:00 UTC for O₃. Only the NO reading is older, dated 21 February 2024, so most pollutants reflect conditions within the past week. Across the city the observed values show a fairly narrow spread for several gases: CO ranges from 220 µg/m³ to 368 µg/m³ with a median of 294 µg/m³; NO and NO₂ are both constant at 2 µg/m³ and 3 µg/m³ respectively; O₃ varies between 71 µg/m³ and 86 µg/m³ (median 78.5 µg/m³); SO₂ sits between 4 µg/m³ and 5 µg/m³ (median 4.5 µg/m³). Particulate matter shows the lowest concentrations, with PM10 recorded at a single value of 13.8 µg/m³ and PM2.5 at 1.88 µg/m³.
Because only two stations contribute data, coverage is limited to those specific sites – LAS FUENTEZUELAS for the gases and RONDA DEL VALLE for the particulates. The dataset therefore captures a snapshot of air quality at these locations rather than a city‑wide picture, and conditions can differ in other neighbourhoods or at times outside the recent measurement window.

Data notes
The data shown for Jaén are based on eight valid measurements and were updated within 3 days, with the latest update recorded at 2026‑02‑09T05:00:00+00:00. This snapshot reflects conditions measured by the network of sensors that met quality criteria at the time of collection. Keep in mind that air‑quality levels can differ across neighborhoods and change throughout the day, so values may not represent every location or moment within the city.
