Air quality today
The air quality in Aranda de Duero is classified as Good today. The primary pollutant measured is PM2.5, with a reported concentration of 3.0 µg/m³, while the accompanying PM10 level stands at 5.0 µg/m³. Five valid measurements were recorded to determine these values.
Data are shown via OpenAQ and reflect the current assessment for this location. 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
The air‑quality record for Aranda de Duero draws on a single monitoring site that supplies seven rows of data, one for each measured pollutant. The dataset includes carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). For each pollutant the most recent entry is dated 2026‑02‑09 15:00 UTC, except for CO, whose latest reading is from 2024‑01‑02 10:00 UTC, and NO, last updated on 2024‑01‑30 00:00 UTC. This means that while the majority of the parameters have been refreshed within the past week, two pollutants rely on data that is more than two years old.
All seven pollutants show a single reported value with no observed variation: CO registers at 1000.0 µg/m³, NO at 4.0 µg/m³, NO₂ at 10.0 µg/m³, O₃ at 66.0 µg/m³, PM₁₀ at 5.0 µg/m³, PM₂.₅ at 3.0 µg/m³ and SO₂ at 2.0 µg/m³. Because the minimum, median and maximum are identical for each substance, the dataset does not reveal any range or spread in concentrations over time. The uniformity of these figures suggests that the current record captures only a snapshot rather than a dynamic picture of air quality fluctuations.
Overall, the coverage is limited to one monitoring location, and while most pollutants have recent timestamps, the older CO and NO entries highlight gaps in temporal completeness. Consequently, the available numbers provide a static view of conditions at a single point in the city, and actual concentrations may differ across neighborhoods or change throughout the day.
